Morphing a face into a vector

I'm currently taking up Vector Analysis and is currently working on a research paper. Is there a way, using matlab, wherein I can input a face picture of someone and represent that face as a vector? I was planning on inputting numerous faces, representing each as a vector, take the average of those vectors and use it as a basis. I would then input a separate face, represent it as a vector and compare it with the basis to compute for the difference.

Basically, I want to create a program/code and database of faces, and when I input an individual's face, the program would output the percentage as to how similar that face is with the database.

Thanks, in advance.

Thank you. I'm new to matlab and this might be too much to ask, but may I know the basic code for said extraction? Basically, may I have your help in the whole procedure?

I have not done any work on feature extraction for images. If you search the forum you will find a lot of discussion of it.

Yes. If the face is stored in YourFaceArray then

 YourFaceVector = YourFaceArray(:);

You will probably find in practice that you instead want to do feature extraction, but you could certainly true with complete faces.
