Title (EN) SYSTEM AND METHOD FOR QUALITY-AWARE SELECTION OF PARAMETERS IN TRANSCODING OF DIGITAL IMAGES
(FR) SYSTÈME ET PROCÉDÉ DE SÉLECTION COMPATIBLE AVEC LA QUALITÉ DE PARAMÈTRES UTILISÉS DANS LE TRANSCODAGE D'IMAGES NUMÉRIQUES
Abstract: front page image
(EN)Several quality-aware transcoding systems and methods are described, in which the impact of both quality factor (QF) and scaling parameter choices on the quality of transcoded images are considered in combination. A basic transcoding system is enhanced by the addition of a quality prediction look-up table, and a method of generating such a table is also shown.
(FR)L'invention concerne des systèmes et des procédés de transcodage compatibles avec la qualité, selon lesquels l'impact des choix du facteur de qualité (QF) et des paramètres de mise à l'échelle sur la qualité des images transcodées sont associés. Selon l'invention, le système de transcodage de base est amélioré grâce à l'ajout d'une table de recherche de prédiction de la qualité, et un procédé permettant la production de ladite table est également mis en oeuvre.
