Image Comparison / Recognition

Does anyone know of an application, web or otherwise, where you can store basic black & white paterns as image files or in a database and compare them to a drawing for the nearest match?

For example lets say I made a simple drawing of a fish or a bird and saved it in a file or database, along with a few hundred other images. I'd like to have a page or application where you can draw with your mouse like in a Paint program (activeX, Java, whatever.. makes no difference to me) and it will compare your drawing to all of the known images and find the nearest match.

Anyone know of anything like this? I know this type of software exists because it's this type of pattern recognition that's used to match everything from finger prints to DNA, but those installations are much more advanced (and costly) than the simple 2-color image recognition I need.

Hi!

I don't know if you can find that kind of software commercially and ready to use.

However, there are lot of projects inside universities developed by AI groups.

If that task its important to your project, I suggest that you may contact a student that work with an AI group and give him your specifications.

The case of classification and recognition of binary pixels images is very simple*. The handle of huge database and fast response is a bigger problem.

*(the classification in this case may be done by an FFT of an appropiate function of the picture border)

Hope this may helps,
