Scientific paper

Facial recognitions of people can be used for the identification of individuals, or can serve as verification e.g. for access controls. The process requires that the facial data is captured and then compared with stored reference data. Different from traditional methods which use 2D images to recognize human faces, this article shows a known shape extraction methodology applied to the extraction of 3D human faces conjugated with a non conventional optical system able to work in ``invisible'' way. The proposed method is experimentally simple, and it has a low-cost set-up.
