ADAPTIVE ENCODING AND DECODING

摘要

The invention relates to a method for transmitting part of an image, said method comprising, in an encoding phase: the analysis of an encoding context; the adaptation of a parameter of a group of prediction functions that can be used for the encoding; the formation of a first predicted descriptor by means of a selected prediction function; and the determination and transmission of a residue (e) between the predicted descriptor and a current descriptor. The inventive method also has a decoding phase comprising: the analysis of a decoding context; the adaptation of a parameter of a group of prediction functions that can be used for the encoding; the formation of a second predicted descriptor (P*)by means of a selected prediction function; and the combination of the second predicted descriptor and the received residue for providing a decoded version (V*) of the current descriptor.
