先生,您可以参考下代码
clc;清晰的所有;关闭所有;
我= imread (“cameraman.tif”);
x =双(im);
c1 = 0.5;c2 = 0.8;c3 = 0.3;c4 = 0.6;
rx = x。* (1 + c1 *罪(π* x / 255) + c2 * (1-cos(2 *π* x / 255)));
gx = x。* (1 + c3 *罪(π* x / 255) + c4 * (1-cos(2 *π* x / 255)));
bx = 3 * x - rx - gx;
rgb = mat2gray(猫(3 rx gx bx));
图;imshow (rgb)
