Title
(EN) IMAGE PROCESSING SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE TRAITEMENT D'IMAGE
Abstract
(EN)
A high-definition image is preprocessed to generate a substantially losslessly-reconstructable set of image components that include a relatively low-resolution base image and a plurality of extra-data images that provide for progressively substantially losslessly reconstructing the high-definition image from the base image, wherein a single primary-color component of the extra-data images provides for relatively quickly reconstructing full-resolution intermediate images during the substantially lossless-reconstruction process.
(FR)
Selon l'invention, une image haute définition est prétraitée pour générer un ensemble pouvant être reconstruit sensiblement sans perte de composantes d'image qui comprennent une image de base de résolution relativement faible et une pluralité d'images de données en surplus qui permettent de reconstruire progressivement sensiblement sans perte l'image haute définition à partir de l'image de base, une composante de couleur primaire unique des images de données en surplus permettant de reconstruire relativement rapidement des images intermédiaires de pleine résolution pendant le processus de reconstruction sensiblement sans perte.
