Face Recognition Based on Eigen Features of Multi Scaled Face Components and Artificial Neural Network
Face recognition has been a very active research area in the past two decades. Many attempts have been made to understand the process how human beings recognize human faces. It is widely accepted that face recognition may depend on both componential information (such as eyes, mouth and nose) and non-componential/holistic information (the spatial relations between these features), though how these cues should be optimally integrated remains unclear. The basic idea is to construct facial feature vector by down sampling face components such as eyes, nose, mouth and whole face with different resolutions based on significance of face component, and then subspace Principal Component Analysis (PCA) or Linear Discriminant Analysis (LDA) method is employed for further dimensionality reduction and good representation of facial features.
