Method of detecting and eliminating pulse noise when processing images and apparatus realising said method / 2449355
Method of detecting and eliminating pulse noise when processing images involves comparing values of the original digital image with different threshold values. A set of penalties is then created for values of the original digital images exceeding the threshold values. The resultant penalty values are formed by adding separate penalty values for each reading. Readings whose resultant penalty values exceed the calculated threshold level are considered abnormal. Further, two-dimensional arrays of penalties are formed for each threshold level. Two-dimensional nonstationarity regions are determined and localised by a two-dimensional programmed detector with subsequent zeroing of the penalty values. The detected pulse noise values are eliminated by replacing them values of a first-order approximating surface on the localised regions.

Method of rounding-off function codes / 2420799
Function codes are rounded-off to the nearest level and the obtained codes are stored. The optimality criterion code is calculated and stored. Starting with a certain initial number L of the function code, the direction of rounding-off this code is changed and the optimality criterion code is calculated. If the optimality criterion code falls, the changed value of the code is stored and a new value of the optimality criterion code is calculated and stored, otherwise the initial L-th function code and the initial optimality criterion code are stored, and calculation is moved on to the next number of the function code L+1, where it is checked whether the optimality criterion code falls in the same way as that when the L-th function code was changed. Further, the process is continued until the optimality criterion code does not fall in a sequence of n function codes, read from the code value in which the last fall in the optimality criterion code took place.
