Abstract: In escapee hunting, face recognition is applied widely. However, face recognition rate is affected by complex lighting environment. So it is a key problem that how to diminish the effect of illumination for face recognition. A re-lighting algorithm is proposed in this paper. First, the inherent texture features of the input image is extracted by selfquotient image algorithm. Then the illumination of the image is normalized based on an illumination bootstrap set. Finally the re-lighting image is produced by the combining texture image and the normalized illumination image. Experiments on AR, CMU_PIE and CAS_Lighting Face Database demonstrate that the proposed algorithm can improve the recall rate of face recognition algorithm, and further help to chase escapee.
