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.
