Introduction With the development of Information technology, biometric identification technology has attracted more attention. Biometric is the automated technique of measuring the physical characteristics and comparing that characteristic to a database.

Face Recognition

PCA Use PCA, to reduce dimensionality.. Training set of images; 1, 2,…… m.

Average image; = Covariance Matrix; C=A AT. where A= [

1, 2………..

m] = .

2D PCA

3D PCA

PCA & IPCA Architecture

Graph Representation for Multi-model

Uses

For security purposes; both resident and government. Law enforcement. Immigration, Identification of missing persons. Payment benefits and to reduce fraud.

Disadvantages Computing Complexity. It can only process the faces with same facial expression.
