Abstract
A method for encoding at least one image split into blocks. The method includes, for a current block to be encoded from the image, at least one modification of two data points in the block via an operation of linear combinations operating on the two data points, at the end of which a modified block is obtained, application of a separable transform operation to the data points in the modified block, and encoding the data points obtained after application of the separable transform operation.
