摘要

本文提出了一种改进的基于亮度的自适应MSR。这种新方法解决了标准Retinex算法中存在的问题，如光环伪影和不正确的颜色。本文选择了一种形状跟随图像边缘的自适应高斯函数，从而减少了高对比度边缘的伪影。此外，只处理亮度通道而不处理所有色带，可以产生更加一致和可靠的色彩再现。

Modified Luminance Based Adaptive MSR

A modified luminance based adaptive MSR is proposed in this paper. This new method addresses the problems existing in standard Retinex algorithms, such as halo artifacts and incorrect colors. The paper chooses an adaptive Gaussian function whose shape follows edges of image, thus reducing the artifacts along high contrast edges. In addition, only the luminance channel instead of all color bands is processed, which can produce a more consistent and reliable color rendition.
