Abstract: A novel illumination normalization method is proposed in this paper to deal with
illumination variations in face recognition. Firstly, Discrete cosine transform (DCT) is used on the
original images in logarithm domain. Direct current (DC) coefficient is reset and some low
frequency alternating current (AC) coefficients are set as zero to eliminate illumination variations
in large areas. Secondly, local normalization method is used on the inverse discrete cosine
transform images to minimize illumination variations in small areas. Experimental results show
that the proposed method can eliminate effect of illumination variations effectively and improve
performance of face recognition methods significantly. The proposed method be used to
eliminate the effect of illumination variations before face recognition. © 2012 IEEE.
