Title (EN) SYSTEM AND METHOD FOR GENERATING VIDEO FRAMES AND CORRECTING MOTION
(FR) SYSTEME ET PROCEDE PERMETTANT DE GENERER DES IMAGES VIDEO ET DE CORRIGER LE MOUVEMENT
Abstract:
(EN) System and method for generating video frames. The system includes a frame generator which generates one or more intermediate frames based upon one base frames. Each of the base frames are comprised of a plurality of macroblocks. In the frame generation process, the frame generator performs a number of steps such as: (i) determines whether frame generation is appropriate, (ii) examines the first and second base frames to check for the presence of textual characters, (iii) selects a frame generation method based upon information in the first and second frames, (iv) filters the generated frames. One aspect of the invention relates motion vector correction and vector smoothing using a median filter..
(FR) Système et procédé permettant de générer des images vidéo. Le système comprend un générateur d'images qui génère une ou plusieurs images intermédiaires à partir d'une image de base. Chaque image de base est constituée d'une pluralité de macroblocs. Dans le processus de génération d'images, le générateur d'images effectue plusieurs étapes telles que: (i) la détermination du caractère approprié de la génération d'image, (ii) l'examen des première et deuxième images de base pour vérifier la présence de caractères textuels, (iii) la sélection d'un procédé de génération d'images sur la base des informations présentes dans les première et deuxième images, (iv) le filtrage des images générées. La présente application porte spécifiquement sur la correction des vecteurs mouvement et le lissage de ces derniers au moyen d'un filtre médian.
