The world is being 3D and the 3D imaging having more advantages over 2D, presently there are attendance system based on fingerprint recognition but that are having some advantages like the surface should be dust free and also the authors have the contact with the sensor so that finger should have to keep properly. There is also 2D face recognition based attendance system. To overcome the problems in 2D i.e. lighting variations, expression variations, variations 3D face recognition is used. They propose a system that takes the attendance of the student using conversion of 2D images into 3D and then face detection and recognition.
