Abstract
A method and device for encoding and a method and device for decoding a signal including encoded data representing an image sub-divided into blocks, and information representing a correction block and a residual block. For a current block of the image, a first pixel is encoded from a prediction value obtained for the first pixel from at least one pixel of a previously rebuilt block. The prediction is corrected using at least one value of a pixel of the correction block. At least one current pixel of the current block is encoded from a prediction value obtained for the current pixel from at least one previously corrected pixel of the current block. The prediction is corrected by using at least one value of a pixel of the correction block, delivering a prediction block for the current block. The residual block is computed from the current block and the predictive block.
