The automatic color equalization (ACE) algorithm, part of the Retinex-derived family spatial algorithms (SCAs), is an image enhancement algorithm that mimics adjustment behavior human visual system (HVS). It commonly used on a unique channel for black & white images or independently three channels images. In this work, we introduce novel application ACE hyperspectral images, referred to as ...

The responses of 20 young adult emmetropes with normal color vision were measured on a battery of visual performance tasks. Using previously documented tests of known reliability, we evaluated orientation discrimination, contrast sensitivity, wavelength sensitivity, vernier acuity, direction-of-motion detection, velocity discrimination, and complex form identification. Performance varied marked...

The well-known simultaneous color contrast effect is traditionally explained in terms of visual color constancy mechanisms correcting for the confounding influence of ambient illumination on the retinal color signal. Recent research, however, suggests that the traditional gross quantitative laws of simultaneous color contrast, which are readily compatible with this functional explanation, shoul...
