Web based face recognition system

Question

I am thinking of building a web based face recognition system. I know there are a few like KeyLemon, and others offered by different manufacturers that allows the laptops users to login into Windows using their face. I am wondering if this functionality could be transfered to a web application.

Answer 1

You may use thing like flash to access to camera ... , and then use the same algorithm to recognize the face ..

Answer 2

suggest you use this as the basis

OpenCV (Open Source Computer Vision) is a library of programming functions for real time computer vision.

There was an excellent podcast on OpenCV on Hacker Medley which has various references that are useful. From that i understand that the library tends to move quite fast in development terms so needs close attention.

Answer 3

I've written a web application which does something similar. And I have to say - I'm quite disappointed at the level of technology we're currently at for such things. The system in question used a 10mpix Canon camera and a special flashlight stand. It had to have a perfectly white background, the head had to be tilted exactly the right way, couldn't be rotated by more than a few degrees, and had to have very precise distances to the edges of the picture. And even then it gave a lot of false positives and negatives.

So maybe they've come up with something better today, but I doubt that. This was all 2 years ago and the software was some commercial product by a company that specializes in that sort of thing.

So all in all I say - better don't. Biometrics are cool, but currently they are way too unstable to be deployed in anything more than niche situations.
