MATLAB之图像分块处理

file_path =  'D:/MATLAB/bin/IMAGES/GreenChannels/_512_pixel/';% 图像文件夹路径
img_path_list = dir(strcat(file_path,'*.tif'));%获取该文件夹中所有jpg格式的图像
img_num = length(img_path_list);%获取图像总数量
if img_num > 0 %有满足条件的图像
        for k = 1:img_num %逐一读取图像
            image_name = img_path_list(k).name;% 图像名
            Im=  imread(strcat(file_path,image_name));

            L = size(Im);
            height=64;
            width=64;
            max_row = floor(L(1)/height);
            max_col = floor(L(2)/width);
            seg = cell(max_row,max_col);
            %分块
            for row = 1:max_row
                for col = 1:max_col
                seg(row,col)= {Im((row-1)*height+1:row*height,(col-1)*width+1:col*width,:)};
                end
            end 

            for i=1:max_row*max_col
            imwrite(seg{i},strcat('D:/MATLAB/bin/IMAGES/GreenChannels/64_512_pixel/','m',int2str(i),'_',image_name));
