A=imread(‘D:\ebook\lena。bmp’);
A1=rgb2gray(A);
B1=A1(1:128,1:128);
B2=A1(129:256,129:256);
B3=A1(129:256,1:128);
B4=A1(1:128,129:256);
B11=histeq(B1);
B22=histeq(B2);
B33=histeq(B3);%%直方圖均衡化
>> figure
subplot(2,4,1),imshow(A1);
subplot(2,4,2),imshow(B1);
subplot(2,4,3),imshow(B2);
subplot(2,4,4),imshow(B3);
subplot(2,4,5),imshow(B4);
subplot(2,4,6),imshow(B11);%%直方圖均衡化結果
subplot(2,4,7),imshow(B22);%%直方圖均衡化結果
subplot(2,4,8),imshow(B22);%%直方圖均衡化結果
