Abstract (en)

[origin: FR2907989A1] The method involves determining a prediction of a part of an image, and determining a residue that is difference between the prediction and the part of the image. Distortion associated to the prediction is determined, and rate and distortion associated to the residue are determined. Decision for coding or not-coding the residue is made based on value of the distortion associated to the prediction, and the rate and the distortion associated to the residue. An independent claim is also included for a device for compressing a part of an image.
