A question (somewhat linux related, but not all the way.)

[Alan Garrison]

Strangely enough I was thinking about trying this 
not too long ago.  My first thought was that if you 
took two images that were approx. the same size (but 
a little different), you could drop the color depth 
in both, pixelate them both to a certain extent, and 
see if the pixel colors matched.  This would probably 
only work if the two pics were nearly identical.  
There are probably better approaches to this problem.

Somebody has probably already tried this, but I don't 
know of any packages (particularly free ones) that 
can do what you want to do.

Ok,  I'm working on a project where I have a large number of images.  Some
of these are repeats of the same image, just scaled or compressed with jpg.
I would like to keep the highest quality of each image, and get rid of the
extras, but as it stands right now, the file names leave me no clue as to
which ones are duplicates.

So, here's the question.  Does anybody know of a software package to do
image comparisons looking for very similar images that might be different
pixel sizes but when scaled are the same image?  Or better yet, does anybody
know of a library that has the necessary functions to pull this off?
Perhaps the GIMP can do it?

If anybody has any ideas.  They are much appreciated.


Thanks,
Jeff
