Abstract
The invention relates to a method of processing data, which may be pixels (P[i,j]) representing a sequence of pictures, previously encoded and decoded. The method comprises at least in series a first step (ED) of detecting edge pixels within a picture, followed by a subsequent step (TEST) in which a choice is made from the pixels not detected as edges in the previous step, as to whether these pixels are to be filtered or not. Then, the method comprises a filtering step (SAF) which consists in replacing at least a pixel to be filtered with a pixel belonging to a close neighborhood of said pixel, said close neighborhood comprising said pixel and pixels adjacent to said pixel.
