Digital Picture Processing and Psychophysics: A Study of Brightness Perception,

Defense Technical Information Center · 1973 · 36 pictures

This is a 1973 technical report from the Defense Technical Information Center, written by Patrick Colas-Baudelaire of the University of Utah computer science department, on digital image processing and how human vision perceives brightness. Its pictures are plain grayscale test patterns of vertical bars with soft and sharp edges, showing how light and dark bands blur, shift in apparent width, and vary in contrast. A designer could take from them a study of gradient falloff, banding and luminance edges.
