MATLAB之圖像分塊處理

file_path =  'D:/MATLAB/bin/IMAGES/GreenChannels/_512_pixel/';% 圖像文件夾路徑
img_path_list = dir(strcat(file_path,'*.tif'));%獲取該文件夾中所有jpg格式的圖像
img_num = length(img_path_list);%獲取圖像總數量
if img_num > 0 %有滿足條件的圖像
        for k = 1:img_num %逐一讀取圖像
            image_name = img_path_list(k).name;% 圖像名
            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);
            %分塊
