Subspace-based face recognition in frequency domain
Asit Kumar Datta, Madhura Datta, Pradipta Kumar Banerjee · 2015
Unlike the design of the correlation filter mentioned in the previous chapter, this chapter provides a design method based on subspace-based reconstruction of faces. Class-specific subspace analysis is carried out for the formulation of correlation filters. Face reconstruction using class-specific subspace provides more information in the discriminating stage. Two types of phase-only filters are developed using the projected images and reconstructed images. Correlation between these two filters is used for the classification process.
