Abstract (en)
[origin: WO2010086544A1] The invention relates to a method for encoding at least one image, divided into macroblocks, one macroblock comprising a set of blocks de pixels. According to eh invention, such a method comprises the following steps for at least one current macroblock of a current image, at least two iterations of the following steps: allocation (31) of a priority level for encoding to at least one pixel of the current macroblock, selection (32) of a pixel with the highest priority level called the priority pixel, prediction (33) of a set of pixels including said priority pixel and an encoding step (35) for a remainder from prediction for a region made up of predicted pixels of said macroblock, called the predicted region, said encoding step being used as and when said predicted region meets a predetermined encoding criterion.
