Title (EN) METHOD AND APPARATUS FOR PROCESSING VIDEO FRAME BY USING DIFFERENCE BETWEEN PIXEL VALUES
(FR) PROCÉDÉ ET APPAREIL DE TRAITEMENT DE TRAMES VIDÉO UTILISANT UNE DIFFÉRENCE ENTRE VALEURS DE PIXELS
Abstract: front page image
(EN)A method and apparatus for processing a video frame is provided. The method includes dividing the video frame into pixel blocks each including a reference pixel; calculating difference values between the reference pixel and pixels neighboring the reference pixel; converting the calculated difference values into values that belong to a bit depth range; and performing entropy coding by using the converted difference values as symbols.
(FR)L'invention concerne un procédé et un appareil de traitement d'une trame vidéo. Le procédé consiste à diviser la trame vidéo en des blocs de pixels contenant chacun un pixel de référence ; à calculer les valeurs de différence entre le pixel de référence et les pixels voisins du pixel de référence ; à convertir les valeurs de différence calculées en des valeurs qui appartiennent à une certaine gamme de profondeurs binaires ; et à effectuer un codage entropique en utilisant les valeurs des différences converties en tant que symboles.
