老外编的的程序，可以成功运行，推荐下载学习-mosaic.m Code Descr iption
The mosaic.m scr ipt operates as follows:
First, it converts the values of the images from unsigned int to double. This is done because most of the MATLAB operations use double as default type. Th

1.图像反转
MATLAB程序实现如下：
I=imread('xian.bmp');
J=double(I);
J=-J+(256-1); %图像反转线性变换
H=uint8(J);
subplot(1,2,1),imshow(I);
subplot(1,2,2),imshow(H);(1. image reversal
The MATLAB program is implemented as follows:
