数字图像处理的数学基础及相关运算：点运算

（1）线性点运算：

>> mission(a);

>> a=imread('guet.gif');

figure(1);imshow(a);

b1=a+45;

figure(2);imshow(b1);

>> b2=1.2*a;

>> figure(3);imshow(b2)

>> b3=0.65*a;

>> figure(4);imshow(b3);

>> b4=-double(a)+255;

>> figure(5);imshow(b4);

>> b4=-double(a);

>> figure(5);imshow(b4);

>> b4=-double(a)+100;
