Abstract
A method is provided for encoding at least one image cut into blocks. The method includes, for a current block having K pixels to be encoded, wherein K>1, acts including: predicting the current block using at least one predictive block having K pixels; then determining a residual block having K pixels and representing the difference between the predictive block and the common block. A set of Mi data is determined from a pixel block group containing a number Mi of blocks having K pixels and each representing a predetermined texture, wherein 1<Mi<K, by calculating the pixel-by-pixel product of the residual block determined by each of the Mi blocks of K pixels representing a predetermined texture, and encoding the Mi data from the determined data set.
