Testing a photo for similarity to other photos

This is strictly an academic question...

Say that I have a library of (somewhat unique) photos. Perhaps photos of small personal objects (e.g. a blue cup, a book with a particular title, a screen on a computer showing a particular webpage, etc.).

How would I go about taking a sample picture and comparing it to the library, and then find the picture in the library that most closely resembles the source picture?

For example, if I take another picture of that blue mug, even though it is not identical to the first, photo, I'd ideally like to compare it to all the pictures, and decide that my library photo of the blue mug is the most similar.

Can anybody point me at some academic discussions or resources that would discuss how a computer system would go about doing this?

I imagine this is the same concept as the way google does "similar images" searching
