Title (EN) METHOD AND APPARATUS FOR COMPRESSION OF VIDEO IMAGES AND IMAGE RESIDUALS
(FR) PROCEDE ET DISPOSITIF PERMETTANT DE COMPRIMER DES IMAGES VIDEO ET DES RESIDUS D'IMAGES
Abstract:
(EN) 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.
(FR) L'invention concerne un procédé de traitement d'une ou plusieurs image(s) vidéo devant être comprimée(s), chaque image comportant des pixels. Ce procédé consiste à filtrer une ou plusieurs desdites images en vue d'augmenter sa/leur compressibilité. Ce filtrage est effectué de manière conditionnelle, la déviation entre l'image filtrée et l'image non filtrée devant rester dans certaines limites. Ladite image vidéo, ou lesdites images vidéo, devant être filtrée(s) comportent une ou plusieurs image(s) vidéo d'origine, une ou plusieurs image(s) résiduelle(s) dérivée(s) d'une ou de plusieurs de ces images vidéo d'origine, ces deux catégories correspondant aux différences existant entre lesdites images d'origine et les prédictions représentant lesdites images d'origine grâce à un modèle.
