摘要
提出了基于矩匹配的色彩平衡算法,在顾及影像间位置关系的基础上将影像的均值和均方差映射到给定的数值,并且使不同区域的灰度均值和均方差近似相等,在尽量保持影像原有色调的条件下消除影像之间以及影像内部的色调和亮度差异。
This paper proposed a color balance algorithm based on moment matching,which maps mean value of the image and the mean square error to a given value on the basis of considering the position relationship between images.Moreover,it made gray scale mean and standard deviation of different regions approximately equal to the value,and eliminated the differences of hue and brightness between the images as well as images inside,as far as possible under the conditions of maintaining the original color of the image.
