Abstract

"PROCESSO PARA CALCULAR UMA DISTANCIA PERCEPTUAL ENTRE UM SINAL DE DADOS E UMA PRIMEIRA REPRESENTAçãO DO SINAL DE DADOS, SISTEMA DE COMPRESSãO, E, PROCESSO DE COMPRESSãO DE DADOS". é provido um sistema para medir a distância perceptual (Fig. 1, blocos 14, 16 e 18) entre um sinal aproximado reconstruído (Fig. 1, 38) e o sinal original (Fig. 1,20). A distância perceptual é a probabilidade de que um humano possa distinguir o sinal original da aproximação reconstruída. O sistema é usado para alocar bits por quantização adaptiva (Fig. 1, blocos 14 e 28) de tal modo que o sinal reconstruído é perceptualmente similar ao original, quando julgado por um humano.
