Hi there, 

I have been working on getting this to work for the project for the last few
days.

There are 2 well established ways of doing it (or so it seems anyway). So I
have found them on MATLAB website and now trying to port the code and framework
in general to C++. So I thought I share how far I got.

I have went with Fisher's face framework first as it seemed more robust then
Eigenface (less dependent on light, pose etc. but not perfect still). However,
the problem that I have encountered is this:
    It needs QZ algorithm to solve generalised eigen value problem to work.
MATLAB has an implementation of it, but I couldn't find an implementation of it
for C++ or anything else other than maths software. It's complex and I don't
want to spend time on it just yet if I don't have to.

Because of this I have abandoned this approach for Eigenface, at least to have
one working no matter how good or bad it is. So I guess I'll get working on
that in next few days and see how far i'll get, hopefully will report with more
success next time :)
