1.3-1
a=imread('xinglong.jpg');
a=rgb2gray(a);
e=log_edge(a,0.25)

1.3-2
a=imread('lena.bmp');
e=canny_edge(a,0.25);
注：该程序要求输入的图像的长、宽应相等。

1.3-3 为1.3-2的子程序

1.3-4
im=imread('lena.bmp');
image_out = susan(im,0.25);

1.3-5 为1.3-4的子程序

1.3-6 直接运行

1.3-7 直接运行

1.3-8直接运行

1.3-9
f=imread('qipan.jpg');
f=rgb2gray(f);
straightline(f)

1.3-10 直接运行(1.3 1
A = imread (' xinglong.jpg ');
A = rgb2gray (a);
E = log_edge (a, 0.25)
1.3 2
A = imread (' Lena.bmp ');
E = canny_edge (a, 0.25);
Note: the procedure requires the length and width of the input image to be equal.
1.3-3 is a subroutine of 1.3-2
1.3 4
Im = imread (' Lena. BMP ');
Image_out = Susan (im, 0.25);
1.3-5 is a subroutine for 1.3-4
The 1.3-6 runs directly
The 1.3-7 runs directly
The 1.3-8 runs directly
1.3-9
F = imread (' qipan.jpg ');
F = rgb2gray (f);
Straightline (f)
The 1.3-10 runs directly)
