摘要： 将Retinex算法应用于彩色图像增强中,在分析MSRCR算法构成的基础上,针对灰度假设(GW)带来的问题作出了改进.改进的算法基于图像自身的直方图,对参数进行自适应的选取.实验结果表明,改进后的算法使彩色图像在演色性(Rendering)方面有了较大的提高,更符合人眼视觉系统的感知特性.

关键词: 色彩恒定性, 彩色图像, 图像增强

Abstract: As an important brightness and color visual theory, Retinex theory has received more and more attention in recent years. We apply it to color image enhancement. Basing on the analysis of MSRCR algorithm, we make use of the histogram of image itself to improve the problem by the GW assumption and choose the parameters adaptively. The experimental results confirm the effectiveness of our algorithm in color image enhancement and the images processed get better rendering by human visual systems.

Key words: color constancy, image enhancement, color image
