Visibility of DCT Quantization Error: Effects of Display ResolutionAs part of a program of research to understand the visibility of DCT quantization errors and thereby design optimal quantizers, we measured visibility of DCT quantization error as a function of display resolution in pixels/degree. Visibilities are consistent with a model incorporating effects of block size and spatial pooling.
