Illumination-Insensitive Face Recognition Using Symmetric Shape-from-Shading

  title={Illumination-Insensitive Face Recognition Using Symmetric Shape-from-Shading},
  author={Wenyi Zhao and Rama Chellappa},
Sensitivity to variations in illumination is a fundamental and challenging problem in face recognition. In this paper, we describe a new method based on symmetric shape-from-shading (SSFS) to develop a face recognition system that is robust to changes in illumination. The basic idea of this approach is to use the SSFS algorithm as a tool to obtain a prototype image which is illumination-normalized. It has been shown that the SSFS algorithm has a unique point-wise solution 25]. But it is still… CONTINUE READING
