Title (EN) ENHANCING VIDEO SEQUENCE SHARPNESS BY ADAPTIVE PEAKING
(FR) AMELIORATION DE L'AFFINAGE DES SEQUENCES VIDEO PAR COMPENSATION ADAPTATIVE
Abstract:
(EN) A method of selectively sharpening video data may include, for at least some pixels in the video data, generating a sharpening value for a pixel value in an image. The sharpening value may be amplified in a non-linear manner to produce an amplified value. The pixel value and the amplified value may then be combined.
(FR) L'invention concerne un procédé permettant l'affinage sélectif des données vidéo. Ce procédé peut consister à générer, pour au moins une partie des pixels des données vidéo, une valeur d'affinage correspondant à la valeur de pixel dans une image. Cette valeur d'affinage peut être amplifiée de manière non linéaire, de manière à donner une valeur amplifiée. La valeur de pixel et la valeur amplifiée peuvent alors être combinées.
