Face detection and recognition using DWT on PCA and DIstance classifier

I am having a java project od face recognition from images developed using JSP and servlet. I want to modify this project with face detection from image and storing that face in project folder with profile details like name, age, occupation, email, phone no, and address etc. When user giving same image for detection system has to generate some message like face already exist in system. In detection phase face has to processed using DWT on PCA. After which when user giving an input image for recognition, System has extract face from that image using DWT and PCA and matching that face using distance classifier with the faces that we stored in early. Here I am giving the giving the work that I have done. Also want to improve PCA and DWT and also need to improve GUI. Here I am Having strict deadline of 6 days.
