Appearance Improvement of Color Image by Adaptive Scale-Gain Retinex Model

摘要

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.
