Patent

CA 2376684

The invention concerns a method for decompressing compressed animated images by a method comprising a block image processing and comprising a step for reconstructing digital data defining predefined forms, a step for modelling the movement of said forms using a forecast, interpolation and time compensation procedure, a step for composing the image from the reconstructed elements, of the Motion-JPEG, or MPEG type. The invention is characterised in that the step reconstructing the forms comprises a process of separating still forms from mobile forms, a process of recording digital data corresponding to the processed still forms by a filter indissociable from the processes used in the reconstituting step in a first specific memory and digital data corresponding to mobile forms in a second specific memory.

L'invention concerne un procédé de décompression d'images animées compressées par une méthode comportant un traitement des images par blocs et comprenant une étape de recomposition des données numérisées définissant des formes prédéfinies, une étape de modélisation du mouvement desdites formes utilisant un processus de prédiction, d'interpolation et de compensation temporelle, une étape de composition de l'image à partir des éléments reconstruits, du type Motion-JPEG, ou MPEG, caractérisé en ce que l'étape de recomposition des formes comporte un processus de séparation des formes fixes des formes mobiles, un processus d'enregistrement des données numériques correspondant aux formes fixes traitées par un filtre indissociable des processus mis en oeuvre dans l'étape de recomposition dans une première mémoire spécifique et des donnés numériques correspondant aux formes mobiles dans une deuxième mémoire spécifique.
