Abstract: “Face Recognition is rapidly growing field due to ease of its application in many vital security systems. In this paper, two non linear dimension reduction techniques namely LLE and ISOMAP are combined for implementing face recognition. Since face image database is believed to be non linear in nature due to varying pose, facial expressions and illuminations , superiority of non linear combination over linear combination is shown. Experimental results based on ORL database demonstrate effectiveness of above statement.”
