Three-dimensional face recognition

Three-dimensional face recognition (3D face recognition) is a modality of facial recognition methods in which the three-dimensional geometry of the human face is used. It is claimed that 3D face recognition methods can achieve higher accuracy than their 2D counterparts.

The main technological limitation of 3D face recognition methods is the acquisition of 3D images, which usually requires a range camera. This is also a reason why 3D face recognition methods have emerged significantly later (in the late 1980s) than 2D methods.

Currently, 3D face recognition is still an open research field, though several vendors already offer commercial solutions.
