Abstract
A method for decoding a coded data stream representing an image. The method includes for a current block: reading from the stream a block size threshold value; determining whether the current block size is less than or equal to the threshold value; if so, decoding information indicating a first or second coding mode and reconstructing the current block according to the indicated mode, and if not, reconstructing the current block according to the first mode. In the first mode the current block is reconstructed using an inverse transform of a transformed prediction residue decoded for the current block, and in the second mode the current block is not reconstructed using such an inverse transform, but by: scanning each pixel of the block, including: obtaining a prediction of the pixel from another previously decoded pixel, and reconstructing the pixel from the prediction and a decoded prediction residue.
