    video_dir = 'snaps/'
    extension = 'jpg'
    out_dir = 'video/'

   resnames=dir(fullfile(video_dirs,['*.' extension]));

   for i=1:length(resnames)
        img=imread(fullfile(video_dirs,resnames(i).name));
        %
        % whatever you want to do with your image
        %
        imwrite(img, [out_dir resnames(i).name]);
    end
