Fourier transform is a widely used image processing technology. Kernel discriminant analysis is an effective nonlinear feature extraction technique. Based on them, we propose a novel feature extraction approach for face recognition. First, we perform the Fourier transform on face images and express the Fourier frequency bands in the plural form. By computing the kernel-plural discriminant capability...
In this paper, a novel discriminant analysis approach using Angular Fourier transform is proposed for face recognition. As a generalization of Fourier transform, the Angular Fourier transform is an important frequency-domain analysis technique. The proposed approach combines it with discriminant analysis method. First, this approach selects appropriate value of angle parameter for discrete Angular...
