matlab彩色图像颜色补偿直方图均衡化

Matlab中实现彩色图像颜色补偿直方图均衡化的方法如下：

1.读入彩色图像并将其转换为YCbCr颜色空间

img = imread('color_image.jpg');
img_ycbcr = rgb2ycbcr(img);

2.对亮度通道Y进行直方图均衡化

Y = img_ycbcr(:,:,1);
Y_eq = histeq(Y);

3.将处理后的亮度通道Y_eq与原图像的色度通道Cb和Cr合并成新的图像

img_ycbcr_eq = img_ycbcr;
img_ycbcr_eq(:,:,1) = Y_eq;
img_eq = ycbcr2rgb(img_ycbcr_eq);

4.显示原图像和处理后的图像

figure;
subplot(1,2,1);
imshow(img);
title('Original Image');
subplot(1,2,2);
imshow(img_eq);
title('Equalized Image');

总代码如下：

img = imread('color_image.jpg');
img_ycbcr = rgb2ycbcr(img);
Y = img_ycbcr(:,:,1);
Y_eq = histeq(Y);
img_ycbcr_eq = img_ycbcr;
img_ycbcr_eq(:,:,1) = Y_eq;
img_eq = ycbcr2rgb(img_ycbcr_eq);
figure;
subplot(1,2,1);
imshow(img);
title('Original Image');
subplot(1,2,2);
imshow(img_eq);
title('Equalized Image');
