A method for color image enhancement using color advanced Retinex has been developed.The new image with larger brightness and contrast can be obtained from an image whose exposure was not enough by enhancing the original image multi-scale Retinex.Then the new images are handled by a Brovey transform while keeping the proportions of red,green,and blue components according to the original images.As a quality criterion of evaluation,the information entropy of the images handled by the proposed method is 1.019±...
1引言1963年E.Land基于视网膜、大脑皮层构造出亮度和颜色的人类感知模型,经过了40多年的发展,Retinex算法成为彩色图像增强领域中的重要算法[1,2],特别是Jobson D J,RahmanZ U,Woodell G A[3,4]等人的努力,Retinex算法的中心/包围形式变得非常实用,对于较暗的曝光不足的彩色图
