Patent

CA 2452550

A method (900) of losslessly compressing and encoding signals representing image information is claimed. A lossy compressed data file (922) and a residual compressed data file (960) are generated. When the lossy compressed data file and the residual compressed file are combined, a lossless data file that is substantially identical to the original data file is created.

L'invention concerne un procédé de compression et codage des signaux sans perte représentant des données images. Un fichier de données compressées avec pertes et un fichier de données compressées résiduelles sont générés. Lorsque le fichier de données compressées avec pertes et le fichier de données compressées résiduelles sont combinés, un fichier de données sans perte, sensiblement identique au fichier de données original, est créé.
