Abstract
A method is provided for encoding at least one image cut into blocks. The method implements, for a current block to be encoded, the acts of: predicting the current block with the aid of at least one predictor block, determining a residual data block representative of the difference between the predictor block and the current block, selecting, according to a predetermined criterion, a pair of mathematical operations including a permutation operation and a transformation operation from among a plurality of permutation operations, and a plurality of transformation operations, applying the permutation operation of said selected pair to the data of the determined residual block, applying the transformation operation of said selected pair to the permuted data, and encoding the data from said applied transformation operation.
