Abstract (en)

[origin: WO9907154A1] A method of processing one or more video images to be compressed, each video image comprising pixels, and said method of processing comprising the step of: filtering one or more of said video images so as to improve compressibility, where said filtering is performed with the constraint such that the deviation between the filtered image and the non-filtered image lies within certain bounds, wherein said one or more video images to be filtered comprises one or more of original video images, residual images which are derived from one or more of said original images as the differences between said original images and predictions representing said original images using a model.
