I have a set of images in image folder located at C:\temp\image. The images are from yale faces, and I want to add extension .jpg to file name(like that subject01.glasses.jpg, subject01.happy.jpg). The original names are like that subject01.glasses, subject01.happy.
I got the error message "Cannot open file "." for reading. You might not have read permission. "
clc;clear all;close all;
f=dir('*');
fil={f.name};
for k=1:numel(fil)
file=fil{k};
new_file = sprintf('%sjpg',file);;
% % new_file=strrep(file,'.jpg','.png')
im=imread(file);
imwrite(im,new_file);
end
