对比了像素间高斯随机配对、伪随机数距离配对及不同固定距离配对对灰度化效果的影响，对Grundland 脱色法进行改进，同时自适应地得到更适合给定彩色图像的对比度增强系数增强灰度图像。实验表明：不同的像素配对方法适合不同主题特色的彩色图像，在改进的脱色法中采用自适应对比度增强系数，可使更多的图像种类获得更加突出的灰度化效果。

Comparing the pixels pairing effect on the gray between Gaussian random pairing,pseudo random pairing and different fixed distance pairing,then modifies the decolorization method of Grundland in the stage of pixels pairing.Mean-while it adaptively generates the contrast enhancement coefficient that is suitable for the color image.Experiments show that different pairing method is suitable for different kinds of color image,the modified decolorize method can handle more diversified kinds of image,what′s more,the proposed new approach to generate adaptive contrast enhancement coefficient results in a more prominent decolorized image.
