face recognition is the most important

challenging in the research area of computer vision.

Different type of illumination takes place from dim light

condition to dark light condition. Two types of condition

are there. a) Controlled condition b) uncontrolled condition.

In this paper we are presenting a detail survey on image

based face recognition under such uncontrolled condition.

Here we explore different technique proposed for

illumination problem and in addition with the classifier that

we have been successfully used for the face recognition in

general.-face　recognition　is　the　most　important
