Abstract (en)
[origin: WO2020058595A1] The invention relates to a method for decoding a stream of encoded data representing at least one image that is split into blocks. For at least one block of the image, referred to as the current block, information indicating an encoding mode, out of a first and a second encoding mode, of the current block is decoded (E42) from the data stream, and the current block is decoded on the basis of this information. When the encoding mode of the current block corresponds to a second encoding mode, the current block is reconstructed on the basis of a prediction obtained, for each pixel, from another, previously decoded pixel belonging to the current block or to a previously decoded block of the image, and a decoded residual associated with said pixel. At least one processing method is applied to the reconstructed current block for at least one pixel of the current block, depending on the encoding mode of the current block and/or the encoding mode of the neighboring blocks.
