Title
(EN) BLOCK-BASED SPATIAL ACTIVITY MEASURES FOR PICTURES CROSS-REFERENCE TO RELATED APPLICATIONS
(FR) MESURES D’ACTIVITÉ SPATIALE À BASE DE BLOCS POUR UNE RÉFÉRENCE CROISÉE D’IMAGES À DES APPLICATIONS ASSOCIÉES
Abstract
(EN)
An encoder includes circuitry configured to receive a video frame, partition the video frame into a plurality of blocks, determine a respective spatial activity measure for each block in the plurality of blocks and using a transform matrix, encode the video frame using the spatial activity measure. Related apparatus, systems, techniques and articles are also described.
(FR)
Un codeur comprend des circuits configurés pour recevoir une trame vidéo, partitionner la trame vidéo en une pluralité de blocs, déterminer une mesure d’activité spatiale respective pour chaque bloc dans la pluralité des blocs et, à l’aide d’une matrice de transformée, coder la trame vidéo à l’aide de la mesure d’activité spatiale. La présente invention concerne en outre un appareil, des systèmes, des techniques et des articles associés.
