Abstract
A method of coding a digital image includes subdividing the image into image blocks formed by a plurality of pixels, and processing each image block of the image, by determining a skip-mode prediction block in respect of the current image block being processed, calculating a difference between the image block being processed and the skip-mode prediction block, and comparing the calculated difference to a predetermined threshold. The calculation of the difference between the current image block being processed and the skip-mode prediction block includes: calculating a plurality of pixel-by-pixel differences between a pixel of the current image block and a corresponding pixel of the skip-mode prediction image block; associating a respective quantized value with each pixel-by-pixel difference; and cumulating the quantized values.
