Fetching images from other location

Hi,

I want to read in x number of images from a folder located in another folder using imread.

How do I do this?

I get error when I write;

base='/Users/..../folder/';
files = dir([base,'*.bmp']); 
PictSize=size(imread([base,files(1).name],'bmp'));

My error message is:

??? Index exceeds matrix dimensions.

Error in ==> CalcLosses at 16
PictSize=size(imread([base,files(1).name],'bmp'));

"files" probably came out empty.

Note: it would be better to use

files = dir( fullfile(base,'*.bmp') );

and then to check whether "files" came out empty.

IT did .. so what could be wrong? I checked the location to "base" and its ok. Images are there.

Still I get,

files =

0x1 struct array with fields: name date bytes isdir datenum

Thanks!

Just want to add that if I am in the folder and write files = dir then I get

files =

51x1 ...

so somethings wrong. I have added the path directly from my mac "info" window so it should be right.

You don't have any files in that location. It might be a relative path since you forgot the drive letter. Maybe try adding a drive letter to get a full directory path and see what happens.

I am working with MATLAB on my USB Passport .. it seems as if this was the problem because if I change the location of the files to the desktop (i.e. the computer) then it seems OK. But if I move the files to the USB again.. the error shows up again.

base = '/Volumes/MyPassport/images/'; vs. base='/Users/XXXXX/Desktop/images/';

Is there way for me to work on the files via my passport. Why is this not working?
