实现多种retinex理论的相关算法，可直接运行-realize the algorithm of retinex，you can run them directly

Abstract. We present a novel 3D face recognition approach based on geometric invariants introduced by Elad and Kimmel. The key idea of the proposed algorithm is a representation of the facial surface, invari- ant to isometric deformations, such
