(54) Title (EN): COMPRESSIVE SENSING WITH JOINT SIGNAL COMPRESSION AND QUALITY CONTROL
(54) Title (FR): ACQUISITION COMPRIMÉE À L'AIDE D'UNE COMPRESSION DE SIGNAL ET D'UN CONTRÔLE QUALITÉ COMBINÉS

(57) Abstract:
(EN): An encoder determines a compression ratio for compressive sensing and a quantization level used to quantize a media signal based on a target indicator. The encoder accesses compressive sensing measurements performed using the compression ratio and quantizes the compressive sensing measurements based on the quantization level. A decoder receives a compressed signal generated from the signal acquired by the signal acquisition device using the compression ratio and the quantization level. The decoder also receives information indicating the compression ratio or the quantization level. T he decoder decompresses the compressed signal based on the compression ratio and the quantization level.
(FR): Selon l'invention, un codeur détermine un taux de compression en vue d'une acquisition comprimée, et un niveau de quantification servant à quantifier un signal multimédia sur la base d'un indicateur cible. Le codeur accède à des mesures d'acquisition comprimée effectuées à l'aide du taux de compression et quantifie les mesures d'acquisition comprimée sur la base du niveau de quantification. Un décodeur reçoit un signal compressé généré à partir du signal acquis par le dispositif d'acquisition de signal à l'aide du taux de compression et du niveau de quantification. Le décodeur reçoit également des informations indiquant le taux de compression ou le niveau de quantification. Le décodeur décompresse le signal compressé sur la base du taux de compression et du niveau de quantification.
