Appearance Improvement of Color Image by Adaptive Scale-Gain Retinex Model
Hiroaki Kotera, Masafumi Fujita · Color and Imaging Conference · 2002
Human vision can see the very wide range of luminance scenes with keeping the color constancy. This paper is addressed to improve the image appearance based on Multi-Scale Retinex (MSR) model. Two linear MSR models are presented based on the adaptive Scale-Gain control for Center/Surround field. The proposed models worked well to compress the dynamic range and to dramatically improve the visibility in shadow areas.
