Abstract

A model is developed for the stochastic noise in digital hardcopy in terms of the basic resolution element (pixel size) and the number of distinguishable gray levels printed within this element. This is expressed in Wiener (power) spectrum terms, and is used to establish a link with a perceptual scale based on previous work concerning the perception of noise for photographic (analog) images.
