Abstract

Understanding the contrast sensitivity function (CSF) of the Human Visual System (HVS) has been in the focus of human psychophysics for more than 3 decades. This effort, despite certain successes, is far from closure. In this paper we present a study on the spatio-temporal characteristics of the HVS. We propose a new method of integration of both spatial and temporal effects in the CSF curve that is to be used in color image quality evaluation. The obtained results are very encouraging and show that the new CSF allows some improvements of the classical quality evaluation scheme.
