Abstract
A spatial prediction method of a block of pixels of an image, called current block, using a plurality of spatial prediction modes based on neighboring pixels of the current block is disclosed. The method comprises determining a prediction block of the current block according to each one of said spatial prediction modes and selecting one of said prediction blocks according to a predetermined criterion. According to the invention, before carrying out the preceding steps, it is detected, among said spatial prediction modes, whether some of them are redundant. If such redundant modes are detected, one of them is replaced by an additional mode, distinct from the other spatial prediction modes.
