how to use Joint Bayesian

Hi, I am curious how to use JointBayesian.m (I want to use the problem like this: run JointBayesian.m inputimage1.jpg inputimage2.jpg and then it returns same or not). I've read the paper Bayesian Face Revisited: A Joint Formulation, it seems that I should first extract lbp features or LE features which I don't know how to do it. By the way, I have the pairlist_lfw.mat and get 89% accuracy after I run the code, which is not the way I want to use. Can you give me some advice? Thank you.
