Relevance of human vision to JPEG-DCT compression
Stanley A. Klein, D. Amnon Silverstein, Thom Carney · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1992
This paper asks how the vision community can contribute to the goal of achieving perceptually lossless image fidelity with maximum compression. In order to maintain a sharp focus the discussion is restricted to the JPEG-DCT image compression standard. The numerous problems that confront vision researchers entering the field of image compression are discussed. Special attention is paid to the connection between the contrast sensitivity function and the JPEG quantization matrix.
