Based on the recovered 3D shape, the "texture image" calibrated to a standard illumination is generated by spherical harmonics ratio image and finally the illumination independent 3D face is reconstructed completely. The proposed method combines the strength of statistical deformable model to describe the shape information and the compact representations of the illumination in spherical frequency space, and handles both the pose and illumination variation simultaneously.

基于此重建的3D形状，进而通过球面谐波商图像的方法估计输入图像的光照属性并提取输入图像的光照无关的纹理信息，从而将光照无关的3D人脸完全重构出来，生成输入人脸图像在标准姿态和光照条件下的虚拟视图，用于最终的分类识别，实现了对光照和姿态问题的同时处理。

Inspired by these results, in this paper, we first give the definition of a new mapping ? uniformly Lipschitz asymptotically nonexpansive mapping on a compact subset of a uniform convex Banach space, then construct three-step iterative sequences of uniformly Lipschitz asymptotically nonexpansive mapping in this subset . We proved the convergence of this three-step iterative sequences for uniformly Lipschitz asymptoticallynonexpansive mapping, Further more, we proved this three-step iterative sequences with an error member converge to fixed points.
