A Retinex and PCA based Face Recognition Method

In this paper, a new Retinex and PCA based face recognition method is proposed to improve the recognition accuracy from images with bad illumination. Retinex algorithm can effectively remove the shadow of light lead to bad image illumination, and the PCA can effectively extract the representative features of images, so allowing rapid and accurate identification become possible. Some experiments are taken on Yale and Yale B database to investigate the performance of the algorithm, and the results show that the proposed algorithm is simple, fast, and can achieve high recognition accuracy. Therefore, it is a feasible face recognition method in practical applications.
