Abstract

The invention relates to a method, an apparatus, a computer program and computer memory means for post-processing decoded video image formed of consecutive still images. In this method, post-processing is repeated at a time for each pixel in a still image, the method comprising: (506) selecting the pixels on both diagonals in a square area formed to surround the pixel to be processed as reference pixels, (510) forming the absolute value of the difference between the pixel to be processed at a time and each reference pixel, and (512, 514) if the absolute value is lower than the quantization parameter of the macro block to which the pixel to be processed belongs, then (518) selecting the reference pixel to form the reference mean, and (534) forming the reference mean of the selected reference pixels, (528, 530) if at least one reference pixel is selected to form the reference mean, and (536) setting the mean formed of the pixel to be processed and the reference mean as the value for the pixel to be processed.
