A human eye can discern the details of a specific face with relative ease. Major strides have been made in face processing in the last ten years due to the fast growing need for security in various locations around the globe. These experiments are conducted using a photometric stereo system, designed and implemented for this research project. ![]() An investigation is presented, which evaluates the capabilities of photometric stereo for use in the area of face recognition by means of a number of experiments. This research project has identified photometric stereo as a low cost 3D capture system, which has been little researched in the area of face recognition. 3D face recognition systems, however, are often expensive relative to 2D alternatives, as precise capture equipment is required. To produce more reliable face recognition systems, a recent trend has been to use three-dimensional (3D) data, which as research has shown is more accurate and robust than traditional 2D techniques. Many two-dimensional (2D) face recognition systems have been implemented, which demonstrate the potential of using face recognition, although at present these systems are often unreliable. At present for face recognition to be a viable personal identification method an accurate low cost solution is required. ![]() Face recognition has received much interest in the last decade, as the need for reliable personal identification security has become ever more critical.
