matlab读取文件夹中所有的图片并写入图片到指定文件夹

Original_image_dir  =    'F:\faces\re\bad';%原始图片路径
right_image_dir = 'F:\faces\re\bad\bad\';%删选出了200*200图片保存路径

fpath = fullfile(Original_image_dir, '*.jpg');

im_dir  = dir(fpath);
im_num = length(im_dir);
NIQE = [];
j=0;
k  = 0;
for i = 1:im_num
    %% read clean image
    IMname = regexp(im_dir(i).name, '\.', 'split');
    IMname = IMname{1};
     im=imread(fullfile(Original_image_dir, im_dir(i).name));
     [msize,nsize]=size(im);       
         k= k+1;
         image_name3=strcat(right_image_dir,num2str(k),'.jpg');
            imwrite(im,image_name3,'jpg');      %写图片      

end
