Abstract

There are many factors for face recognition. Two of those are orientation and brightness of illumination. In early studies of face recognition, with fixing these factors to good conditions the goal of research was focused on improving recognition rate itself. But they are very important factors to be solved for implementing face recognition system. In this paper, two methods were proposed to minimize the influence of illumination. One is the local difference filter to reduce the influence of variation of illumination. The other is weight function considering the horizontal difference of intensity. Applying two proposed methods, the resultant recognition rate revealed 86.5% for 275 test images.
