[Imtoolkit-users] Comparing 2 images

[Milind G. <mil...@gm...>]

Hi,
     I don't have any experience with image processing so I needed some
help. I want to compare 2 images know if the image content is the same in
them. If its possible to define a threshold for the similarity something
simple like 80% of the pixels match that would be really helpful.
      Which functions in IM can I use to do this?

Thanks,
Milind
