@Aditya,
I had a look at the "paper" they have published recently and the module itself and not particularly convinced. For example, the system doesn't learn, which means it is limited to the original raining data. As I understand it, this modules uses eyes for face tracking and authentication. There is no guarantee what the eyes will be like in a photo, e.g. an eye is covered tilted rotated and occluded.
The module has high rejection rate for security reasons, and that is something is opposite to what we want here. In practical aspects it builds dxd matrix somewhere inside where d is number of pixels in an image. Take an average 7M pixels image and make that a square. What you get is something unfeasable. Or at the very least needs a lot to optimise. Where as working off a 320x220 image from webcam is a different story. It makes no mention on the limitations of the system, rotation in both x-y plane and z axis is not mentioned as well as the image intensity invariance. What is the limit on how big a face it can detect? In the demo they have on website it only detected image when tester moved closer.
Based on what I have just said and more I am very skeptical about this module. However, having said this I think there are some worth while ideas there like MACE filter and Local Binary Pattern. Perhaps interesting things can also be done with eye detection.
I don't think there is a single system that will do the trick, but instead a number of systems for face detection and recognition put together, working together to reinforce one another will be the best thing in the end.
I don't want to discourage you from trying this approach, so if you write the class based on what they have used, one for face detection and/or one for face recognition feel free to send it to me and I will try to integrate into the library.
By the way since the last post I managed to upload the library to libface (on sourceforge) and this is where it is going to be hosted permanently now. Feel free to download the library and compile it, but be warned the work is still very much in progress :)
