Abstract
A method and device for compressing at least a portion of a video image such that a compressed video stream includes, or does not include, an encoding of a residual depending on whether it is advantageous to do so in terms of costs in rate and in distortion. The size of the video stream and resources needed for decompression are optimized through encoding only the most relevant data in the video stream. If the information added by the residual is insufficiently relevant or useful, the residual is not encoded. Factors associated with the residual are only encoded if use of the residual limits the distortion in a satisfactory manner and if the encoding of the associated factors does not generate too high a rate. Use of the method makes it possible to optimize resources needed for a decoder by optimizing the encoding of the residual.
