(EN) BLOCK-BASED PICTURE FUSION FOR CONTEXTUAL SEGMENTATION AND PROCESSING
(FR) FUSION D'IMAGE BASÉE SUR DES BLOCS POUR LA SEGMENTATION ET LE TRAITEMENT CONTEXTUEL
Abstract
(EN)
An encoder includes circuitry configured to receive a video frame, partition the video frame into blocks, determine a first area within the video frame including a first grouping of a first subset of the blocks, determine a first average measure of information of the first area, and encode the video frame, the encoding including controlling a quantization parameter based on the first average measure of information of the first area. Related apparatus, systems, techniques and articles are also described.

La présente invention concerne un codeur comprenant un circuit configuré pour recevoir une trame vidéo, diviser la trame vidéo en blocs, déterminer une première zone à l'intérieur de la trame vidéo comprenant un premier groupement d'un premier sous-ensemble des blocs, déterminer une première mesure moyenne d'informations de la première zone, et coder la trame vidéo, le codage comprenant la commande d'un paramètre de quantification sur la base de la première mesure moyenne d'informations de la première zone. La présente invention concerne également un appareil, des systèmes, des techniques et des articles associés.
