DCTune: A Technique for visual optimization of DCT quantization matrices for individual images  (1993)
Abstract Header
Image compression standards based on the Discrete Cosine Transform do not specify the quantization matrix. This matrix should be designed to provide maximum visual quality for minimum bitrate. I show how this goal can be achieved for individual images in the context of a DCT-based model of visual quality.
