Due to digitization and for security purpose a lot of research has been going on in the wide area of affect computing. One of the field under this affect computing is to recognize the human faces with maximum accuracy. There are still large numbers of difficulties to recognize the accurate facial expression. In this paper, the authors are going to represent their experimental results for facial recognition by using Principal Component Analysis (PCA) algorithm. So in the first section of this paper they discussed some algorithm for facial recognition, than compare their results of research with these algorithm.
