Limited person face recognition by Principal Component Analysis (PCA) and Histogram

Face recognition system is a computer application which automatically identifies person from digital image from source. Face recognition involves: Face detection, feature extraction and matching with database images. Face is detected from images by using Viola-Jones algorithm using MATLAB, and some features like eye, nose and mouth are also extracted. Then face is recognized by PCA method by using latent and in Histogram method by using median value by comparing it with stored database of the images.
