Combination of improved modular 2DPCA and maximum scatter difference discriminate analysis for face recognition
Kong Aixiang · Computer Engineering and Applications Journal · 2014
A method of combination of improved modular 2DPCA and Maximum Scatter Difference discriminate analysis(MSD)is proposed. The improved modular 2DPCA is applied to the original face images for feature extraction. Then MSD is used to the sub-images of these obtained feature images in which way the final feature images are obtained. This method can not only exploit local features of original image and discriminate information but also totally avoid the problem of singular value decomposition of matrix. Experiments performed on ORL face database verify the effectiveness of the proposed method.
