Please help this is for our thesis, and its our first time to use matlab, this was required by our adviser, we search a lot but we can't understand that much, we are working in to detect the different facial expressions, we want to know what would be the code for feature extraction and feature detection.

You can start your review of prior literature here: http://iris.usc.edu/Vision-Notes/bibliography/contentspeople.html#Face%20Recognition,%20Detection,%20Tracking,%20Gesture%20Recognition,%20Fingerprints,%20Biometrics in section 21.3.6. I guess the first step would be to replicate the latest greatest paper. Then you need to identify shortcomings of that method, or several methods, and devise your own improved algorithms. As you know getting a Masters or Ph.D. is not merely running someone else's code, or showing that you have an improvement over some early papers (which have long since been improved upon). You need to show that your new algorithm is an advancement in the field.
