Abstract

Basic considerations are given about the effect of static and dynamic noise on the contrast sensitivity of the eye and a numerical evaluation is made of published data on this subject. The results of this analysis are used to extend the square-root integral method for the evaluation of subjective image quality in such a way that it also can be applied to describe the effect of noise. Using an adapted version of the square- root-integral, calculations are made for experiments with pictures with various amounts of white noise found in literature. From a comparison between measurements and calculations, it appears that the image quality calculated in this way shows a very good correlation with the measurents.
