matlab写的 处理图片白平衡的三种方法

第一种，选取图片中最亮的点作为white

第二种，手动选取任一点作为white

第三种，求RGB的平均作为white

其中包含了rgb xyz等空间转换代码，有CAT02， 和VK chromatic adaptation transforms

适合颜色科学相关专业-1. the brightest object in the imge is just white.

2. select a white object from the image

3. assume the average color data of the image is just a medium gray, get the white from this.

others: the color space transform, RGB to XYZ, the chromatic adaptation transform code: cat02, VK.

A 2nd level of color science.
