A system for measuring the perceptual distance (Fig. 1, blocks 14, 16, and 18) between an approximate reconstructed signal (Fig. 1, 38) and the original signal (Fig. 1, 20) is provided. The perceptual distance is the likelihood that a human can distinguish the original signal from the reconstructed approximation. The system is used to allocate bits by adaptive quantization (Fig. 1, blocks 14 and 28) such that the signal reconstructed is perceptually similar to the original when judged by a human.
Système de mesure de la distance perceptuelle (Fig. 1, blocs 14, 16, 18) entre un signal reconstruit approximatif (Fig.1, 38) et le signal original (Fig. 1, 20). La distance perceptuelle correspond à la probabilité qu'un humain puisse distinguer le signal original de l'approximation reconstruite. Le système de l'invention est utilisé pour l'attribution de bits par quantification adaptative (fig. 1, blocs 14 et 28), de sorte que le signal reconstruit soit perceptuellement similaire à l'original lorsqu'il est évalué par un humain.
