Face Recognition, Overview
Face recognition is the science which involves the understanding of how the faces are recognized by biological systems and how this can be emulated by computer systems. Biological systems employ different types of visual sensors (i.e., eyes), which have been designed by nature to suit a certain environment where the agent lives. Similarly, computer systems employ different visual devices to capture and process faces as best indicated by each particular application. These sensors can be video cameras (e.g., a camcorder), infrared cameras, or among others, 3D scans. The essay reviews some of the most advanced computational approaches for face recognition defined till date.
Many types of biometrics exist for identifying a person or verifying that a given individual is what he or she claims to be. Some of the biometrics result in quite reliable recognition and verification, but most are either...
