I need to read several images from a folder in MATLAB Directory, in order to do several operations on it, I have written the following code:

Directory = fullfile ('C:','Users','ssr729','Documents','MATLAB','image');
Images = dir(fullfile(Directory,'*.jpg'));
Names = {Images.name}';
for k=1: numel(Names)
       I = imread(Names{k});
         %operations
end

I am receiving this error and I do not know why:

Error using imread (line 372)
File "polymerc.jpg" does not exist.

Even though the image 'polymera.jpg' does exist in the specified path. Any help is really appreciated. Thanks

Thank you F.

Well, apparently the images live in the C:\Users\ssr729\Documents\image folder and not the C:\Users\ssr729\Documents\MATLAB\image folder. It will work if it looks in the right folder, and it won't work if it looks in the wrong folder - makes sense?

Your error states that

Error using imread (line 372) File "polymerc.jpg" does not exist.

Even though the image 'polymera.jpg' does exist in the specified path

Notice the difference between ploymerc and polymera The two files are different..

Thanks Binish for pointing this out, but in the folder I have the two images '*polymera*' and '*polymerc*' and still I have the mentioned error above.
