Abstract

This paper presents a different way of using DCT and LBP to com-pensate for illumination variations in face recognition with only one sample image per person. The sensitiveness to lighting variations of the LBP and DCT methods was investigated and from it emerged the proposed new method, consisting in discarding low-frequency DCT coefficients in the logarithm domain in a local way as a preprocessing step, and applying LBP method to represent the facial features. Experimental results on the Yale B database show that the proposal improves the performance of the original methods and their existing extensions.
