The main challenge experienced by the present face recognition techniques and smooth filters are the difficulty in managing illumination. The differences in face images that are created by illumination are normally bigger compared to the differences in inter-person that is utilized to differentiate identities. However, face recognition over illumination has more uses in a lot of applications that deal with subjects that are not cooperative where the highest potential of the face recognition as a non-intrusive biometric feature can be executed and utilized. A lot of work has been put into the research and development of illumination and face recognition in the present era and a lot of critical methods have been introduced. Nevertheless, there are some concerns with face recognition and illumination that require further considerations which include the deficiencies in comprehending the sub-spaces in illumination pictures, problems with intractability in face modelling and complicated mechanisms of face surface reflections.
