Abstract
A method for decoding a data stream representative of an image split into blocks. The method includes: for a current block, determining whether the size of the current block is less than or equal to a threshold, and if so, decoding information indicating a coding mode of the block among first and second coding modes, and reconstructing the current block according to the indicated coding mode, and otherwise reconstructing according to the first coding mode. According to the first coding mode, the current block is reconstructed using an inverse transform of a transformed prediction residue decoded for the current block, and according to the second coding mode the current block is reconstructed, for each pixel, by obtaining a prediction of the pixel from another previously decoded pixel belonging to the current block or to a previously decoded block, and reconstructing the pixel from the prediction and a decoded prediction residue.
