On the Limits of Perceptually Optimized JPEG
2010
Fifth International Workshop on Video Processing and Quality Metrics for Consumer Electronics (VPQM-10)
The study presented in this paper aims at quantifying the empirical limits of JPEG optimization, when the compressed stream is standard compliant and only the quantization tables are optimized. Image-dependent quantization tables, which minimize the bitrate of the compressed image while maintaining transparent visual quality, are identified by means of a psychovisual experiment. The results demonstrate that significant room for improving JPEG compression efficiency is available.
