The invention relates to a method for encoding at least one image (ICj) cut into blocks. Said method includes, for a current block (Bu) having K pixels to be encoded, wherein K > 1, steps that involve: - predicting the current block using at least one predictive block (BPopt) having K pixels; then - determining a residual block having K pixels and representing the difference between the predictive block and the common block. According to the invention, the encoding method includes the steps that involve: - determining (C5), from a pixel block group (G,) containing a number Mi of blocks having K pixels and each representing a predetermined texture, wherein 1 < Mi < K, a set of Mi data 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 (C7) the Mi data from the determined data set. |
