有些图像处理任务的目标是根据颜色分离出不同类型的物体，但由于常用的彩色成像设备具有较宽且相互覆盖的光谱敏感区，加之待拍摄图像的染色是变化的，所以很难在3个分量图中将物体分离出来，这种现象称为颜色扩散。彩色补偿的作用就是通过不同的颜色通道提取不同的目标物。-Some image processing tasks, the target is separated according to color the different types of objects, but change the color imaging device has a wider and cover the spectrum sensitive areas, combined with images to be shot staining, it is difficult in the three component diagram in an object separated from the phenomenon known as color diffusion. Color compensation is through the different color channels to extract different objects.
