图像的增减

原标题：rgb of an image

获取罗姆妇女价值观:

RGB = imread( C:Documents and Settingsstudent2DesktopWater lilies.jpg );
R = RGB(:, :, 1);
G = RGB(:, :, 2);
B = RGB(:, :, 3);

谁能告诉我,为什么我们分别使用1、2和3台红色、绿色和蓝玉米。

问题回答

如果你看一下RBG的大小:size(RGB),你就会看到它高X。每个六氯代苯有3个数值,即红色、绿色和蓝色;六氯苯的实际颜色是这些主要颜色的混合物——Wikipedia 。

If you want to know the reason why R is 1, G is 2 and B is 3, rather than R being 3 and B being 1 or something, it is just convention. I assume because red light is a lower frequency of light, blue is higher and green is in between - Wikipedia.
