“…The shadows produced in facial images due to variation in lighting directions may cause loss of important facial features which are helpful for recognition. A preprocessing method must enhance the intensity in the regions of inadequately illuminated and decrease the intensity in the densely illuminated regions while retaining the intensity in the fairly illuminated portions [37]. Few important preprocessing techniques are discussed below.…”

“…Moreover, LBP is sensitive to local illumination variations and is no longer able to correctly perceive the texture of facial muscle tissue and different sorts of local deformations. In [13] .et al suggests how to handle the illumination variation for face images.…”
