Visibility of DCT quantization noise: Effects of display resolution  (1994)

The Discrete Cosine Transform is widely used in image compression. To better understand the visibility of DCT quantization errors and thereby design better perceptual quantizers, we measured visibility of DCT quantization noise as a function of display visual resolution in pixels/degree. Visibilities are consistent with a model incorporating effects of block size and spatial pooling.
