1. A method for decoding a signal representing at least one image, comprising: implementing at least one iteration of the following steps, for at least one block to be decoded of said image: determining with a decoding device at least one selection parameter, from at least one characteristic associated with at least one reference pixel of a reference region of said image, said reference region comprising at least one previously encoded/decoded block and/or at least one pixel predicted at a preceding iteration, selecting with the decoding device at least one pixel to be predicted in said block to be decoded, from said at least one selection parameter; and For at least one selected pixel to be predicted, called an anchor pixel, predicting with the decoding device said anchor pixel from at least one reference pixel of said reference region, delivering a predicted pixel.
