Face Recognition for Attendance System

I am making a recognition based attendance system for a class room as my Final Year Project. Face detection is done using Voila Jones, I want to compare the faces detected in the first minute of lecture with the ones detected at the end of the lecture in a closed classroom. The faces at the start will be Training data, i want to do it without Neural Network. Already tried following techniques :

- Corelation

- Nose / Mouth Matching for face recognition

But the results of recognition are not satisfactory. Is there any other direction through which the Recognition / Matching Faces can be done.

Brett from the Mathworks has two Face detection/recognition apps in his File Exchange: http://www.mathworks.com/matlabcentral/fileexchange/index?term=authorid%3A911 Try one of his algorithms.
