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
