文件列表遍历和多通道图片裁剪

文件遍历和多通道图片裁剪

% 加载文件路径列表,文件个数为sz(1)
filelist  = textread('R:\Users\HaoGe\Desktop\fs\all_figures.txt','%s','delimiter','\n');
sz=size(filelist);    

%读取样本  
for i=1:sz(1)  
   name= char(filelist(i,1));  
   image=imread(name);
%    ms = size(image)
%    m = ms(1)
%    n = ms(2)

%    [m,n] = size(image)
%     [m,n,c] = size(image)
%    m = m/4;
%    n = n/4;
       m = 898;
       n=898;
   
   for j=1:4
       for k=1:4
           imwrite(image(1+m*(j-1):m*j,1+n*(k-1):n*k,:),[name,num2str(j),num2str(k),'.bmp']);
           
       end
   end
   %imshow(image);
end
