There are several approaches. Usually you measure a bunch of stuff and compare that to the same measurements from other images in your database. Basically you need to look up CBIR (Content Based Image Retrieval). It can be very good but sometimes not. You have images that are taken with different magnifications, different parts of the scene, different exposures and times of day, etc. So you may say "find me images of beaches" and get tons of them. Maybe some of them will be that particular beach but there may be other beaches too. It's a challenging but rapidly improving field.

Any chance you'd be willing to share the original photos you posted of the beach scene? I'd like to post a response to your question on a MathWorks external blog, but I the previous images that were linked to this question illustrated a point I wanted to make better than these
