I have already developed such kind off projects for engineering students.
I have made some 'Face & Eye recognition' codes to detect from live camera or stored images using C#.net.
For that i used EmguCV wrapper classes with c#.
So, i think i will easily fulfill your expectation.
I m a new user for this site.
This is my first project, which is i m beading on this site.
So, being first client, I would like to give you some offer.
I will submit complete code without any payment or terms and conditions.
If u like my code than its up to you what to pay.
Thx.
