例程1.2-1
in_image=imread('qingdao.jpg');
inv_m7 = invariable_moment(in_image);
注：输入图像应为RGB图像；若要是输入的是灰度图像，应去掉image=rgb2gray(in_image);

例程1.2-2
img=imread('qingdao.jpg');
img=rgb2gray(img);
[A_nm,zmlist,cidx,V_nm] = zernike(img);
注：输入图像应为灰度图像；(Routine 1.2 1
In_image = imread (' x.jpg ');
Inv_m7 = _table_moment (in_image);
Note: the input image should be an RGB image. If the image is a gray image, the image = rgb2gray (in_image) should be removed.
Routine 1.2 2
Img = imread (' x.jpg ');
Img = rgb2gray (img);
[A_nm, zmlist, cidx, V_nm] = zernike (img);
Note: the input image should be grayscale image;)
