VIDEO SIGNAL POST-PROCESSING METHOD

摘要

The present invention relates to a method of post-processing pixels contained in a sequence of digital images. Said method comprises a step (200) of detecting pixels belonging to natural contours (20) inside an image. It also comprises a step (210) of detecting an investigation zone (21) corresponding to a coding block. It comprises a filtering decision step (220) such that a current pixel is filtered if it has not been detected as being a natural contour pixel (20) and if it belongs to an investigation zone (21) containing at least one natural contour pixel (20). Finally, the method comprises a pixel filtering step (230), of the median filtering type, for the pixels to be filtered.
