Robust linear discriminant analysis
WebA simple statistical analysis has been used to select the discriminant coefficients of the discrete cosine transform for the face recognition. The proposed procedure is different from the traditional zigzag or zonal masking. It searches for coefficients which have more ability to discriminate different classes better than other coefficients. Webrobust way than conventional methods. This LLR measure can be further formulated as a non-linear discriminant classifier and solved by kernel-based techniques, such as the Kernel Fisher Discriminant (KFD) and Support Vector Machine (SVM). The results of experiments on two speaker verification tasks show
