FIELD: information technologies.

SUBSTANCE: images are produced in a multi-level codec of the first flow with the first dynamic range and the first colour space, and the second flow of the image with the second dynamic range. The first flow of the image is produced by performance of a local tonal display on the second flow of the image, using the functional form that displays a family of curves of the tonal image, parametrised by means of one parameter, besides, the first dynamic range is less than the second dynamic range, and the first flow of the image is in the base layer, and the second flow of the image is in the expansion layer. The multi-level codec includes a decoder and a coder. The first flow of the image is coded in the base layer using a coder to produce the coded first flow of the image. The coded first flow of the image is decoded using a decoder to produce a decoded first flow of the image. The decoded first flow of the image is converted from the first colour space into the second colour space of the second flow of the image to produce the colour first flow of the image. Parameters of the reverse tonal image are generated on the basis of the converted colour flow of the image and the second flow of the image, where parameters of the reverse tonal image approximate the second flow of the image when applied to the converted colour flow of the image.

EFFECT: increased efficiency of coding.

THE AREA OF TECHNICAL APPLICATION

[0002] This disclosure relates to video technology and, in particular, to coding, processing and/or compression of the video.

BACKGROUND OF THE INVENTION

[0003] Images displayed modern video displays such as CRT, LCD and plasma displays tend to have a certain color gamut and dynamic range within the scope of the narrow dynamic range (LDR).

[0004] the Term «dynamic range» for any image can refer to a range of characteristics of the image (for example, brightness, lightness) or against the strongest criteria, or intensity, given the characteristics of the image to the weakest criteria, or intensity, this characteristic. In some cases, the weakest criterion characteristics of the image can be noise. In some cases, the characteristic of the image may be luminosity, color, combination of luminosity and colour or luminosity function and/or color.

Dynamic range also may be cited as the ratio between the maximum bright and maximum dim, but not in black pixels in the image. This ratio can vary little from the contrast, which may be cited as the ratio between the brightest and black (for example, off) pixels. Human visual system can recognize up to ten orders of magnitude full dynamic range, and can contain both visible dynamic range, about 5-6 orders of magnitude. Video displays can have a dynamic range of 2-3 orders of magnitude.

[0005] colors may be cited as the space of all colors that can be captured or displayed a particular device. Video and computer screens can represent the colors inside the triangle whose vertices are chromaticity red, green and blue primary colors on any of the color chart acc. to CIE.

The residual signal may include the difference between the image with extended dynamic range and prediction based on images with a narrow dynamic range, or the difference between the visual dynamic range and prediction based on images with a narrow dynamic range.

[0030] In other aspects of technology involves a way of encoding and decoding codec. The method involves the generation of the compressed bit stream at the encoder codec, where the generation of the compressed bit stream includes: receiving encoder input stream of the image with a narrow dynamic range (LDR); encoding and decoding of the input stream LDR image to produce the first internal bitstream, LDR and decoded flow LDR image; and the transformation of the decoded stream LDR image in the visual space of the dynamic range (VDR) using the conversion unit inside the encoder.

[0031] These and other embodiments of the present invention may optionally include one or more of the following features.

Conversion may include the generation of a logarithmic luminosity of L D fixed-point and colour coordinates (u' D , v' (D ). The generation of the compressed bit stream at the encoder can also include artifact suppression of quantization in a transformed LDR via the to obtain the first bit stream LDR. Conversion decoded flow LDR image in the visual space of the dynamic range (VDR) using the conversion unit at the encoder may include: performing analysis of tone mapping (TM) on the first bit stream LDR to generate the parameters of tone mapping; perform reverse tone mapping (ITM) on the first bit stream LDR; and generating a residual signal that depends on the result of the reverse tone mapping input bit stream with visual dynamic range (VDR). The method may also include: processing of residual signal encoding treated residual signal; get the first residual bit stream; the reception unit first residual bit stream, the first internal bitstream, LDR and parameters of tone mapping; and getting the output of the encoder compressed bit stream. The method may include coding parameters of tone mapping in the block encoding tonal mapping. The method may include the generation of output bitstream VDR in the decoder codec that will decode the compressed bit stream. Generating decoder output bitstream VDR may include: reception decoder compressed bit stream; parse the compressed bit stream in the second bitstream LDR, bitstream tonal mapping and second internal residual bit stream; decoding of a second internal bitstream, LDR; and the transformation of the decoded second internal bitstream, LDR in the space visually dynamic range (VDR) in the decoder through the use of conversion unit inside the decoder.

Analysis of the reverse tone mapping may include calculations using the parameters of tone mapping. Any tonal mapping or reverse tone mapping is performed in the codec can enable the function of a parameterized global operator of tone mapping, function parameterized operator local tone mapping, function parameterized operator reverse global tonal mapping or function parameterized operator reverse the local tone mapping. Any parameterized operator local tone mapping or parameterized operator reverse the local tone mapping can enable the function with many curves of the second order.

Generation at the encoder compressed bit stream may also include: lowering the discretization of the residual signal; and compression subjected to a decreasing sampling residual signal. Codec may be a codec without drift. VDR-image may include dynamic range the range of 5-6 orders of magnitude luminance of video.

[0035] These and other embodiments of the present invention may optionally include one or more of the following features. The first dynamic range of the video image can be a high dynamic range (HDR), the second dynamic range of the video image can be a narrow dynamic range (LDR), and the third dynamic range of the video image can be a visual dynamic range (VDR).

The method may include residual signal, where the residual signal can represent the difference between the image with extended dynamic range and prediction based on images with a narrow dynamic range, or the difference between the visual dynamic range and prediction based on images with a narrow dynamic range. The size of the residual signal can be zero, and then the image obtained from the residual signal is an invisible image. The size of the residual signal can be approximately zero, and then the image obtained from the residual signal is an invisible image or largely invisible image. The operator of tone mapping, the corresponding operator to reverse the local tone mapping, or the operator to reverse the global tonal mapping, can be monotonous, and the operator to reverse the local tone mapping, or operator reverse global tonal mapping, can be parameterized. The third dynamic range of the video image can be a visual dynamic range (VDR) video where dynamic range VDR-video image can be 5-6 orders of magnitude luminosity.

Parameterized operator reverse tone mapping may include the first non-linear plot high luminosity, the second nonlinear plot of low luminosity and line section between the first and second nonlinear areas.

[0038] Any of the methods and techniques described in this description may also be implemented in the system of one or more components in the machine or device, machine, computer software product, software, hardware, or any combination. For example, a computer software product may be coded on a machine-readable carrier and may include machine commands that lead to the execution of device data processing (for example, processor data) one or more operations for any of the methods described in this specification methods.

[0039] Technology with less visible residual images may constitute a technology with a higher efficiency of coding and compression. To illustrate how these techniques can be implemented, will be illustrated and described several illustrative embodiments of the invention.

HIGH DYNAMIC RANGE (HDR), NARROW DYNAMIC RANGE (LDR) AND VISUAL DYNAMIC RANGE (VDR)

[0040] Different methods are used to capture, display and view images and videos may have different dynamic ranges. For example, photographic negatives may have a relatively wide dynamic range compared with a dynamic range of photographic images. Similarly, television and computer monitors may have a relatively narrow dynamic range compared with photographic negatives. Image formation with the extended dynamic range can provide improved image quality and accuracy of information transfer.

[0041] Images with high dynamic range (HDR), for example, pictures «aimed subjects») strive to accommodate the entire dynamic range, available in the original subject. On the other hand, an image with a narrow dynamic range (LDR) (for example, image, «aimed at the output, or images, «aimed at demonstrating») have significantly less wide dynamic range and can be shown, for example, on 8-bit displays (for example, LDR displays).

[0042] There are a large number of applications, especially compression, for dissemination and demonstration, which are most suitable for dynamic range is between HDR and LDR. These applications can use the visual dynamic range (VDR). The VDR can cover luminosity and color that the human eye can perceive simultaneously. VDR-system may include imaging systems that operate in visible within the perception of the human visual system, and in some cases may cover the entire luminosity and the colors that the human eye can perceive simultaneously. The VDR can be a perfect target dynamic range for the distribution and consumption of moving images.

[0043] On .1 shows a chart with an example of the differences between dynamic ranges for high dynamic range (HDR) 103, narrow dynamic range (LDR) 101 and visual dynamic range (VDR) 102. Chart on .1 maps ranges of 100, including the full range apparent luminosity (for example, HDR), with a range of luminosity that is visible at a time, and the range of an 8-bit display with gamma-display (for example, LDR). Simultaneously visible dynamic range can be a dynamic range for VDR. Dynamic range for VDR may be less than dynamic range for HDR, but more than dynamic range for the LDR. In some cases, VDR may have a range of HDR less range associated with adaptation.

[0045] Requirements for dynamic range to capture formats, distribution and consumption can vary between HDR and VDR. Formation of HDR images can include capture and display image with full dynamic range and color spectrum that are visible to the human eye. Mainly, HDR can be a capture format. VDR, besides the fact that he is a potential format seizure may also be suitable for dissemination formats, and consumption. For example, VDR-format could allow compression and wide dissemination of images with high dynamic range as through a broadcast network (e.g., wireless, cable and satellite), packaged media (for example, DVD, Blu-Ray discs, other data carriers), and/or via download through the Internet. VDR-format also allows you to easily transfer images with high dynamic range and wide colour gamut in current and future displays and image formats.

[0046] Some options for compression related to VDR may include compatible compression. Compatible compression may include creating a compressed digital stream, which is manifested as valid for existing devices MPEG-2 or MPEG-4/AVC (H.264) (for example, is shown as the current format such as MPEG), and also carries information to obtain images with high dynamic range and wide colour gamut on devices that have the ability. Compression can include all that the human eye could perceive, and, in some versions, of the invention may be a last transition required in respect of a dynamic range of possible colors, to achieve these results.

[0047] On .1 shows a chart of the stages 105 production and distribution on the example of the film. At the stage of 106 production data HDR image original subject is captured by a digital HDR-camera 120 or film camera, then exposed to digital scanning 130. Real capture real-time events can be combined with computer animation (CGI) 140 during the final stage of processing. Real capture and final stage of processing can occur in the field of HDR. After the end of the final stage of the processing the output signal can be fully represented as a stream of 160 VDR-image, which may flow 165 LDR image. At the stage of 108 distribution RSS 160 VDR-image, or RSS 165 LDR image may be distributed in digital cinemas 170, on digital media such as optical drives, 180, or through the network broadcasts 190 (for example, through broadcasting networks with wireless delivery or delivery via the Internet).

[0048] Any dynamic range outside the VDR can be invisible without additional processing (for example, tone mapping). The VDR can include dynamic range of the response of the retina of the human eye. VDR may provide a reasonable target dynamic range displays.

[0049] VDR may include full color. The VDR can be considered as the format of the wide colour gamut (WCG). In some embodiments of the invention, the WCG-format can be considered as a color gamut that is broader than standard digital television, which can largely be a standard recommendation 709 of the International telecommunications Union (ITU Rec. 709). In one example, VDR, VDR can be displayed extremely effective: almost to ¼JND (barely noticeable differences between the luminosity and colour, with 32 bits per pixel. The VDR can use 32 bits per pixel to accommodate 12 bit luminosity and 10-bit per color channel. The number of bits used for the luminosity must be greater than the number of bits used for each color channel, because the human eye may be more sensitive to the perception of the luminosity than the perception of color. 32 bits per pixel can be used in computers for processing and transmission of information (for example, 32 - and 64-bit machines). Regarding the effectiveness of the number of bits per pixel for VDR may be less than the number of bits used in digital cinema, where can be used 36 bits per pixel.

[0050] In some embodiments of the invention, the VDR data can be displayed via the colour coordinates XYZ acc. to CIE (for example, the coordinates in the color space (XYZ)that may be of elementary incentives in the three-component additive color model, which coincides with the model of color), in the region to quantization into digital values fairly homogeneous perception. The conversion process will begin with coordinates R'g'b' with gamma correction, where the coordinates R'g'b' may primarily be converted in the region of linear light, RGB, by recourse to/cancellation of the gamma correction. The resulting RGB coordinates can be transformed in color coordinates XYZ by a matrix transformation. Conversion applied to AYZ-coordinates may be parameterized by a generalization of the LogLuv encoding format. XYZ coordinates can be transformed into a representation of luminosity log(Y) with the coordinates (u',v') for the color. Data logarithmic luminosity can be uniform for the perception of high levels of adaptation, whereas gamma-encoded luminosity can be almost homogeneous for the perception of lower levels of adaptation. Accordingly, gamma encoding may be more effective for dark environment, as, for example, in theatres. However, for the luminance range in most applications logarithmic encoding can provide better results than gamma encoding. And although logarithmic encoding at low light levels may not be more effective than gamma encoding, this is compensated by the ability of the logarithmic encoding allow to increase or decrease the full brightness of the image without making banding (for example, distinct stages in a smooth gradient), which may occur when using a gamma-encoded images. In some embodiments of the invention, the ability of the logarithmic encoding allow to increase or decrease the full brightness of the image may be important to control the display in different viewing conditions.

For VDR logarithmic luminosity L D fixed point can be calculated from the physical luminosity Y in CD/m 2 using the S scale and offset In, expressed in equations 1 and 2:

[0051] In equation 2, linking zero numeric value of zero luminosity, the result may be similar to the result of the LogLuv encoding. Parameter S of scale can determine the relative resolution for the luminosity, which is expressed by equation 3:

[0052] In one of the embodiments of the invention, if S=256 - scaling factor to be used in the LogLuv, then permission is 0.27%, which is close to the traditional 1% JND. The number of bits of N for the logarithmic luminosity along with the S scale can determine the dynamic range DR:

[0053] If S=256, then the resulting dynamic range depends on the number of bits N luminosity, as illustrative of dynamic ranges in table 1.

DR@ S=256(-1/4 JND)

1,8 x 10 19

4,3 x 10 9

6,5 x 10 4

[0054] Scale factor S can allow you to configure the format for its compliance with various requirements. For example, may require dynamic range of 10 6 . When reducing's from 256 to 205, dynamic range for N=12 becomes equal to 1.03 x 10 6 with a resolution of 0,33%, or roughly 1/3JND.

[0055] Parameter offset can be used to determine the full range of luminosity in CD/m 2 . For example, if N=12, S=256 B=6, the minimum luminance Y min and maximum luminance Y max will be equal, respectively, 0,0157 and 1022,6.

L D =1 o Y min =0,0157

L D =2 N -1 O Y max =1022,6

[0056] Because Of 1.5/S can be a small value, approximation Y min

minimum the luminosity can be Y min ≅2-B .

[0057] Color part of the VDR can use the coordinates (u',v')determined by the projective transformation (for example, transformations used in projective geometry) on the colour coordinates XYZ:

where the inverse transform can be expressed as

[0058] color performance of the fixed-point uses Mbit, where M > = 8, can be expressed as

[0059] Coefficient of 410 in equation 7 can be used to display range (u', v'), which can approximately be [0, 0,62], in [0, 255] and can in full use integer range of 8 bits. When 8-bit per component color resolution does not exceed one JND.

TONE MAPPING: THE DYNAMIC RANGE HDR AND VDR

[0064] «Tone mapping» may entail displaying one set of colors in a different color set, and can be used to reduce the dynamic range of the HDR and VDR-image. In some cases, tone mapping can reduce the dynamic range of luminosity, but leaves unchanged the color of each pixel. In these situations, tone mapping can modify L D , but leaves intact (u' D , v' (D ).

[0065] There are at least two types of tone mapping operators: operators of the global tone mapping operators and local tone mapping. Global tone mapping can refer to a transformation that includes the same transformation for all the pixels. Global tone mapping may include conversion of HDR or VDR-luminosity LDR-luminosity. Local tone mapping can contain a transformation that includes a conversion capable vary for different pixels. Local tone mapping can also include the conversion of the HDR - or VDR-luminosity LDR-luminosity. Global tone mapping, local tone mapping, or a combination can be used to display HDR - or VDR-luminosity in the VDR-luminosity.

[0066] for Example, in one of the variants of the implementation of the global tonal mapping all pixels HDR-type (or VDR-type) with a certain value of luminosity, for example, L1, may appear in the same luminosity, for example, L2. In another example, in one of the options for the implementation of local tone mapping luminosity for the specified pixel HDR-type (or VDR-type) can have a value of luminosity L1, however, displayed LDR-luminosity are not the same (for example, not all displayed LDR-luminosity can have a value of luminosity L2).

[0067] global Operators of tone mapping can be more simplified than operators of local tone mapping. In the global tone shown, for example, you can have one common feature for all pixels, which displays the HDR - or VDR-luminosity in the LDR-luminosity:

where TM[] - the function that implements one-to-one mapping. The operator of the global tonal mapping can have an «S»shape.

[0068] figure 3 shows a chart example of the global tonal mapping 300. Curve 320 global operator of tone mapping is marked on the graph of the dependence of log(Y HDR ) 310 from the log(V LDR ) 305. Curve 320 global operator of tone mapping in General has an «S»shape. Curve operator global tonal mapping can be mapped to a single form 315 (for example, straight, slant line; linear). Curve 320 operator global tonal mapping also has three sections: linear, or close to the line, plot 335 for the luminosity of the wholly within the dynamic range of LDR, and sections 325, 345 - for nonlinear transformations, respectively, at very high and very low . Tonal image shown in FIGURE 3, is an example and may oversimplify some used (for example, in the real world) operators of tone mapping, at least because some of the most frequently used of tone mapping operators may differ slightly from the strictly linear transformation near values of the luminosity in the middle range.

[0069] On the section 325 high luminance values deviate from a single tilt 315 decrease, while on a plot of 345 low luminance values deviate from a single tilt 315 towards increase. Deviations operator 320 tone of reflection from a single tilt 315 can contribute to the reduction of the full dynamic range. As a result of compression on nonlinear areas luminosity on the sections 325, 345, can resolve details in light and/or dark areas. For example, when the LDR image obtained from tonal mapping, quantized 8 bits, compression at the edges of the luminosity can resolve details in very bright and very dark areas.

[0070] figure 4 shows examples of images 400 is intended to illustrate the loss of detail for high-and low-luminosity at the tone mapping HDR in the LDR. Each line contains the number displayed LDR image 410 scaled version of this LDR image 420, HDR image 430, scaled for blurry LDR image 420, and the scale factor is used to scale the LDR image 410 into the scaled LDR image 420. The first line 450 is used to illustrate the loss of components at high luminosity, the second line 460 used to illustrate the loss of components at low luminosity. In the first line of 450 on the LDR image 452 shows a relatively bright part of the picture. When the scale of the image 452 reduced to 1/10, letting the image 454, bright sky contains fewer details. However, when HDR-version 430 scales to approximate matching scaled the LDR version 420, as shown reference position 456, details in the clouds remain visible. Thus, the first line of 450 shows that detail in the bright areas of the image can be lost when the tone is displayed.

[0071] And Vice versa, the second line 460 shows a loss of detail at low luminosity. LDR image 462 shows a relatively dull area of the image of a boat and a crowd of people on the shore. When LDR image 462 scaled 14 times the image of 464, on which there is much less visible parts, in a crowd of people. However, when the HDR-version scaled to approximate matching scaled the LDR version, the resulting image 466 detects much more details in the crowd. Thus, tone mapping can resolve details in the image areas with high and low-luminosity.

[0072] Using tonal mapping can mean not just adding extra bits to luminance or RGB. For example, adding more bits can show the detail in darker areas of the image, but not in brighter areas of the image. For example, as shown in figure 3, adding more bits can be equivalent to function of tone mapping, which is a single function plus the fixed zoom level. For example, the transition from 8-bit to 12-bit can represent a single function plus zoom ratio 16. However, simply adding more bits may not contain compression at high luminosity 325 or at low luminosity 345, which characterized would tonal mapping.

[0073] Along with the operators of the global tonal mapping, which displays extended into the narrow dynamic range is the same for all the pixels may be a multiplicity of operators of local tone mapping, where the display may vary from pixel to pixel. Operators of local tone mapping can be considered in terms of a family of curves of tone mapping, as shown in figure 5.

[0074] figure 5 shows an example of a parameterized family of operators tonal mapping. A family of curves 565, 575, 580, 585 tone mapping is marked on the graph of dependence of log(Y HDR ) 310 from the log(Y LDR ) 305 parameter µ. Curves 575, 580, 585 tone mapping operators have an «S»shape when µ PD 0 (for example, when setting µ does not create a single tilt for tone mapping operator). Figure 5 curves 575, 580, 585 tone mapping operator have the «S»shape when µ=0,5, µ=1,0, µ=1,5. Each member of the family of curves of tone mapping operators, i.e. one value of m can match operator global tonal mapping.

[0075] figure 5 also shows the similar concept of «increasing the contrast of the» 520 and decrease the contrast» 510 of photographic practice. In the pictures «the increase contrast and reduces the contrast can be used for manipulations with the exposition of one or more areas of the photographic image, where the reduction in contrast reduces the exposure of areas that need to be done more dull, and increases the contrast increases the exposure of areas that need to make more vivid.

[0078] In some embodiments of the invention, the VDR/HDR can be generated, at least initially, from reverse global tonal mapping. In the variants of the invention, where VDR/HDR can be generated from reverse global tonal mapping, can analyze the tonal mapping. In some embodiments of the invention, the reverse global tone mapping can be applied to and converted LDR for creation of the device prediction for VDR/HDR. In some variants of realization of the invention for VDR/HDR can be processed and decoded the residual signal (for example, correction signal). Information about VDR/HDR may include information for the layer extension.

[0079] In some embodiments of the invention, the LDR image may be part of the operator of tone mapping that applies to the VDR/HDR. In some of these options when trying to move from LDR to a VDR/HDR big change in the magnitude of dynamic range may require the use of local tone mapping. In some versions of the global tone mapping can include the image in full (for example, curve «S»), and the local tone mapping may include local changes, where local changes can be parameterized. In these variants of carrying out the invention can also be seen quantization and coding error correction.

THE REVERSE TONE MAPPING TO PREDICT

[0080] Because LDR can be obtained by HDR tone mapping and/or VDR, applying the reverse tone mapping to the LDR image can give an approximation of the target HDR - and/or VDR-image. In one example, if the function LDR-pixel luminosity

, expressed as

- luminosity of the image for LDR, and VDR, and TM[] - the General operator of tone mapping,

where TM -1 [] - generalized operator reverse tone mapping.

[0081] due to more coarse quantization in the LDR image and probability the fact that the reverse tone mapping is not known exactly should be included correction, called «residual signal»

. The residual signal

can be added to the TM -1 [] to increase the accuracy of resulting HDR - and/or VDR-image, which is expressed by the equation 11:

[0082] Some embodiments of the invention include ways to increase the accuracy of the operation of the reverse tone mapping. With increasing precision reverse tone conversion you can reduce the residual signal

[0083] In some embodiments of the invention, the original operator of tone mapping is global and famous, and then its inversion can be used directly applied to images LDR-luminosity. If the global operator of tone mapping is unknown, may be permitted assessment of this statement, the methods of statistical estimation by balancing the number of variables or unknown parameters describing the reverse tone mapping with the precision with which these variables, or unknown parameter can be defined.

EXAMPLE CODEC

[0084] figure 6 shows an example of a compatible codec 600. The codec includes 600 VDR/HDR-coder 620, LDR decoder 630 and VDR/HDR-decoder 640. VDR/HDR-coder 620 can receive RSS 605 VDR/HDR-image and corresponding RSS 610 LDR image and shape of the flow 605 VDR/HDR-image and corresponding thread 610 LDR image compliant bitstream 615. Bitstream 615 can contain two components. The first component can be decoded LDR decoders 630, giving the output stream 645 LDR image corresponding to the input stream 610 LDR image. The second component may include information that allows you to generate a stream of VDR-image (or HDR image) from a compatible bitstream 615. The second component is packaged in such a way that information about the VDR/HDR could be ignored standard LDR-decoder 630. Such architecture encoding can be called «multilevel codecs». In this case the coded LDR of the first component may form the base layer, and more information about VDR/HDR for the second component can represent a layer extension. Information from the first and second components can be decoded by the VDR/HDR-decoder 640, giving the output stream 650 VDR-image (or HDR image), the corresponding input stream 605 VDR/HDR. Compatible codec can refer to the codecs that are able to generate a compressed bit stream, compatible with existing standard LDR decoders. Some types of compatible codecs may include JPEG compatible codecs HDR-type for images and compatible MPEG codecs HDR-type for image sequences, such as video or digital cinematography. In codecs JPEG HDR-type and MPEG HDR-type LDR and residual signal are correlated. This effect can be seen by visual comparison LDR and two residual signal, where the original image in the residual signal can be visible in varying degrees. When LDR and residual signal are correlated, one and the same information can be encoded twice: one encoding - in LDR, and the second encoding - layer extension HDR (or VDR) (in different degrees). Dual encoding of the same information applies to JPEG HDR, and MPEG HDR.

INCREASED EFFICIENCY OF CODING IN THE VDR-HDR AND WCG-VIDEO

[0085] Described and shown in this description of embodiments of the invention can increase the effectiveness of coding for compatible encoding video with extended dynamic range, such as the VDR - or HDR-image, along with the encoding of the video with a narrow dynamic range, such as the compressed bit stream LDR. Prediction for HDR or VDR-image can improve by modifying the reverse tone mapping, which is used to predict HDR - or VDR-image of the corresponding LDR image.

[0086] Some embodiments of the present invention may use the HDR or VDR, which uses a logarithmic representation for the luminosity of the HDR or VDR-image. Technology logarithmic luminosity allows low complexity without reducing the coding efficiency.

[0087] Some embodiments of the present invention may provide for application technology to LDR operations before reverse tone to suppress the display of artifacts of quantization in a LDR.

[0088] Some embodiments of the invention may be used for the operation of the global tonal mapping with the goal of predicting HDR or VDR from LDR total parameterized wording. These options may be forcing such target properties of tone mapping, as monotony, and, at the same time, minimize the statistical uncertainty in assessing the tonal mapping. For example, by setting the parameterized form for tone mapping with a number of parameters (for example, with less than 255 parameters), the statistical reliability of these parameters can be made more sustainable, and the result can be generated on a small residual signal (or residual signal may not be generated).

[0089] Some embodiments of the present invention may use a parameterized opposite local tone mapping, which may include a image compression parameters.

[0090] Some embodiments of the invention can use to LDR and residual signal codecs without drift.

[0091] Some embodiments of the present invention may before compression expose the residual signal decreasing sampling.

[0092] Some embodiments of the present invention may contain a compatible encoder, which may include operations alignment of color and luminosity in the LDR and HDR, analysis of tone mapping, calculation of the residual signal and compression residual signal.

INFRASTRUCTURE CODEC

[0095] decoder block 752 parser accepts compliant bitstream 750 from the block 745 . Block 752 parser sends bitstream 754 LDR in block 782 LDR decoder bitstream 780 TM - block 756 decoding TM, and residual bitstream 758 - block 798 decoding and processing the residual signal in the decoder. Block 782 LDR-decoder generates LDR D 784, decoded stream LDR image, which is converted to a color space VDR/HDR in block 788 conversion. In the course of the transformation generated luminosity L D and (u' D , v' (D ) - dimensional representation LDR D , which is designated as LDR T 790. Block 791 «» suppresses some of the artifacts of quantization in a LDR T 790, generating LDR* 792, designed to send in the unit 793 reverse tone mapping (ITM). Block 756 decoding TM displays the parameters 724 MT in block 793 reverse tone mapping (ITM). The output signals of the block 793 ITM and block 798 decoding and processing of residual signal sent to the unit 794 adder, and from the block 794 adder is generated output VDR/HDR-signal 795. Following are some of the features of the codec 700.

AN EXAMPLE OF A CODEC 700

[0096] Below are some of the features of blocks encoder 744. For the proper decoding of the encoded bit stream some particular blocks decoder 748 can be mirror-like blocks encoder 744.

[0097] encoding Process may begin with the encoding of the input bit stream 704 LDR to generate the encoded bit stream LDR and the next quickly followed him decode this stream to generate LDR D 710. In some embodiments of the invention, the encoding may forcibly be «exact match». «Exact match» can mean that subsection encoder LDR (for example, unit 708 encoder and decoder) in full encoder 744 and subsection decoder LDR (for example, block 782 decoder LDR) in full decoder 748 are exactly the same. In the absence of exact correspondence to the flow of the decoded image LDR D 710 at the encoder and a similar thread LDR D 784 in the decoder may not be the same. The lack of precision of compliance can lead to visible glitches on the resulting final image. Codec exact match can be called a «codec without drift.» Other options for carrying out the invention, however, can use the codecs without requiring an exact match, such as MPEG-2 and MPEG-4 part 2. MPEG-4 part 10 (for example, H.264/AVC), for example, can enforce an exact match, and so can be used to block 708 encoder and decoder and/or block 782 decoder, and set the bit accuracy decoder. In some embodiments of the invention, the codecs H.264/AVC can be used for systems that generate base layer (for example, containing information about the LDR) and layer extension (for example, containing additional information to display VDR/HDR).

[0098] The options for implementing unit 712 convert image stream LDR D 710 can be converted to the color space of VDR/HDR. In some embodiments of the invention, the VDR/HDR image can be displayed using color space L D and (u' D , v' (D ), as described with reference to FIGURE 2. For the case when the LDR image are R'g'b'images with gamma encoding conversion example of figure 2 can be used as part of the block 712 transformation FIG.7. One of the options for the implementation of the block 712 conversion, gamma correction may be canceled for the generation of a linear referencing RGB. Coordinates of RGB can be transformed by famous matrix generating color coordinates XYZ acc. to CIE. The colour coordinates XYZ acc. to CIE may be converted to a color space L D and (u' D , v' (D ). Display LDR D by L D and (u' D , v' (D ) may be represented as LDR T 714.

[0099] In some embodiments of the invention, the unit 718 may be of a design intended to suppress some quantization artifacts that may be present in the LDR T 714. Quantization artifacts may occur due to the 8-bit quantization LDR T 714 compared with 12-bit quantization L D for VDR and 14-bit quantization of HDR. Reduction function may be performed using, for example, bilateral filtering. In some embodiments of the invention, the unit 718 is optional because the quantization errors can also be corrected using the residual signal. In some codecs using block can increase the efficiency of coding. The output signal of the unit 720 , or when the unit missing, LDR T 714, is sent to the unit of analysis of tone mapping that uses an input signal and VDR/HDR-data 702 for the simulation of the reverse tone mapping between the data 702 LDR and VDR/HDR.

TONE MAPPING

[00101] For the analysis of global tonal mapping, you first choose the functional form of the display between LDR and VDR/HDR. This functional form can include any number of parameters.

[00102] On FIG.8 shows an example of the architecture of global tonal mapping 800. FIG.8 includes General form of analysis of global reverse tone mapping. Block 820 evaluation parameters accepts the input signal LDR* 810, input 805 VDR/HDR and functional form 815, generating vector of parameters

825, showing options for the specific callback function of tone mapping for the input signals. In one example, as the functional forms used polynomial in terms of the equation 12:

[00103] Vector of parameters

includes specific for a given set of input signals polynomial coefficients.

is L D for VDR/HDR, and

is L D for LDR. In some variants of carrying out the invention, when using the values of L D for LDR and VDR/HDR for all pixels in the image to determine the coefficients of the polynomial forms for a given set of input signals can be used valuation method of least squares or other method of valuation metrics error (for example, can run the calculation of estimates 820 settings for optimal approximation polynomial).

[00104] Parameterized form of tone mapping and its treatment may provide enhancements reconstruction, at least in respect of monotony and reduce noise. In most applications function of tone mapping suitable for use in case they are monotone, as if

increases (or decreases),

also should increase (or decrease). The function of tone mapping for their use in most applications should also be smooth. Otherwise tone mapping may introduce unwanted distortion in the residual signal.

[00105] figure 9 shows an example of architecture of local tone mapping. FIGURE 9 includes the block 920 determine at least one parameter for each pixel. Block 920 accepts the input signal 910 LDR*input signal VDR/HDR 905 and the functional form of the 915 to generate the image parameters

925, where

can display the position of the pixel in the image. In some embodiments of the invention, the analysis in case of local tone mapping may be similar to the global tonal mapping. For example, pre-determined functional form 915 and calculation of one or more of the parameters of this functional form. One of the differences of the local tone mapping from the global tonal mapping is that in the local tone mapping functional form can display a family of curves of tone mapping parameterized by, for example, through one common option. For example, a parameterized family, similar to the one shown in figure 5, you should see the family of curves of the second order, which is expressed by the equation 13, which can be used as a functional form for the local tone mapping:

[00106] For each pixel block 920 can determine the appropriate value µ and generate the image parameters

, which displays the value of µ for a pixel in the position

[00107] figure 10 shows an example of a parameterized reverse tone mapping 1000 of the second order. An example of a parameterized reverse tone mapping 1000 of the second order can be used for functional form. A family of curves of the second order 1015-1040 is plotted on the graph of the dependence

from 1010

1005. When µ=0, display an isolated one, and when µ increases, displaying become much more of an S-shaped. Thus, µ can display the degree of contrast increase or decrease the contrast to a single pixel.

[00108] In some embodiments, the implementation of the invention to achieve the best presentation of the complete reverse of tone mapping can use any of the common functions F[] G[], which is expressed by the equation 14:

[00109] Function F[] G[] can also be assessed from the LDR and VDR/HDR images by analysis of tone mapping several small spatial areas in a way that is similar to running for an entire image at the global tone mapping.

[00110] As described above, block 920 can perform finding µ depending on the position of the pixel

when generating the image parameters

925. Depending on the chosen functional form of picture parameters can be smooth and .

[00111] In some embodiments of the invention, the image parameters can be piecewise constant on a set of rectangular blocks. This model can be very effective, since the effects of local tone mapping is often limited to relatively small parts of the image. To compress the fields of motion can be used various methods of image compression parameters.

[00112] In some embodiments, the implementation of the invention after the determination of the parameters of tone mapping is performed (for example, block 728 ITM by FIG.7) reverse tone mapping. Some ways to reverse tone mapping can use global, or a parameterized local, reverse tone mapping to LDR*generating prediction for VDR/HDR-image. The prediction may be deducted (for example, block 730 on FIG.7) from the input signal VDR/HDR, generating residual signal 732 and accurate prediction.

[00113] In some embodiments of the invention, the, you can avoid errors related with the function of reconstruction. In addition, in some embodiments of the invention, the residual signals can be very small (for example, usually zero, except for areas of very high or very low luminosity, where the influence of tone mapping may be the greatest), which may include reduced, or minimum, processing and/or encoding the residual signal. Since the residual signals can be zero or close to zero, the layer extension may contain a small amount of information, and therefore the quantity of official information for these embodiments of the invention may be small.

[00114] For color channels (u' D , v' (D ) LDR and VDR may be deducted, generating residual signal. The residual signal may be non-zero when the color VDR/HDR is outside the range LDR. Since most of the colors available in nature, is inside or near the LDR range, the residual signal (u' D , v' (D ) may be zero for the vast majority of pixels. In some cases, despite the fact that the channel logarithmic luminosity may require reverse tone mapping to generate a good estimate of the logarithmic luminosity HDR or VDR, the color channels (u' D , v' (D ) may not contain this requirement.

[00115] figure 11 shows an example of processing of residual signal. Processing of residual signal may be used, for example, to implement blocks 734 and 798 processing of residual signal. Processing of residual signal is indicated for the codec, which contains the encoder 1130 with input residual signal 1103, passing through several processes 1105, 1110, 1115 for output bitstream 1120 residual signal, and the decoder 1135, which contains the input bit stream 1120 residual signal passing through several processes 1140, 1145, 1150, generating decoded residual signal 1104. At the encoder 1130 input residual signal 1103 filtration 1105 lower frequency, decreasing sampling 1110 (for example, twice the horizontal and vertical directions) and coded 1115, generating residual bitstream 1120. In the decoder 1135 residual bitstream 1120 can be decoded 1140, be Overdrive sampling 1145, and the upper frequency deleted by filtering 1105 lower frequencies can be reconstructed 1150, generating decoded residual signal 1104. In some embodiments of the invention, the residual bit stream can represent the same residual bitstream 1120 for the encoder and decoder; however decoded residual signal 1104 may differ from the original input residual signal 1103, subject to the encoding as the encoding can represent a lossy. Accordingly, residual bitstream 742 at the encoder 744 on FIG.7 may be the same residual bit stream 758 decoder, and the residual signal in the decoder 748 may differ from the residual signal 732 at the encoder.

[00116] If desired, the decoder can be used the methods of reconstruction of high-frequency information in the residual signal as those used in JPEG HDR, as shown in figure 11. In some embodiments of the invention, the residual signal subjected to a decreasing sampling, can be encoded in 1115 the same, encoder, and that the encoder used for LDR708. The encoder may be a coder type H.264/AVC (Advanced Video Codec) (for example, MPEG-4Part 10, MPEG-4 AVC) or its equivalent. Some encoders for these embodiments of the invention may be called encoders «AVC VDR».

[00117] Returning to FIG.7 output signal processing may include three bit streams: one bitstream - for encoding 738 LDR, one bitstream - for information 740 tone mapping, and one bitstream - compressed residual signal 742. As shown in FIG.7, the bit streams can be formatted way, specific encoding LDR used to generate the compressed bit stream 750. H.264/AVC and to the same extent, other codecs may provide mechanisms for the transfer of this redundant information, which can be called «metadata».

[00118] When the same bitstream 750 appears in decoder, as shown in figure 7 and 11, the decoder can mirror the encoding process without any need for analysis of tone mapping, the analysis of the tone mapping already made by the encoder.

ILLUSTRATIVE IMAGE

[00119] Some visible results disclosed technology can be illustrated by an example with a residual image, received with use of the offered technologies (for example, in accordance with FIGURE 4-11 and associated description). In this example, tonally displayed image is shown in .12, and residual image, obtained with the use of the proposed technology (shown in .12). Technology with less visible residual images can display technology with higher coding efficiency and greater compression.

[00120] On .12 shows an example of tonally mapped HDR image 1205. Image 1205 displays a frame from the sequence of HDR images sunset 1207. The dynamic range of the image may be within range LDR-luminosity, except call 1207 setting sun and its reflections in the mirror 1208 in the water. Image 1205 has a dynamic range of 10 6.5 sunset 1207 and flips 1208 for image 1205 are tonally displayed.

[00121] On .12 is an example of a residual image 1220. Residual image 1220 can be rendered in accordance with such a codec, the codec 700. For example, a residual image 1220 can be generated in accordance with the disclosed technology (for example, in accordance with FIGURE 4-11 and associated description). In this example, we used the global tone mapping with the reverse function of tone mapping in the form of a polynomial of fourth order. In this residual image 1220 setting sun partly apparently, flips partly visible, but are much more dull, and the rest of the image is invisible or apparently in a very vague, significantly below the limits of quantization is used for coding LDR. When using disclosed technologies for encoding the residual image 1220 and .12 may require less information. Accordingly, the number of service data required for data on the residual image 1220 and .12 in the bit stream is small.
