Hi all,

I am trying to set up a database of images that can be used to compare
to a current image (So if the current image is equal, or almost equal
to the one being compared it'll give a match)

However to start this project off I want to just compare 2 images
using Matlab to see how the process works.

Does anyone know how I might compare say imaeg1.jpg and image2.jpg to
see how closely related to each other they are? So basically if I was
to compare image1.jpg and image1.jpg the relationship should be 100%,
but comparing 2 different images might give me quite a close
relationship.

I hope that makes some sense!!!

Thanks,

Niall.
