DCT is one of the novel normalization techniques for illumination variation. The technique is in-
corporated by truncated the low frequency DCT Coecients. In face image illumination, changes
slowly compared to re
ectance. As a result illuminations are mainly in Low frequency components.
Since we attempt to recognize face image by its re
ectance characteristic, illumination variations can
be reduced by removing low-frequency components.
