matlab图像分为8块,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),&#
