ABSTRACT
This chapter reviews the statistical and the mathematical algorithms which so far have been used in facial recognition. It describes the use of facial recognition technology as the primary means by which to confirm the identity of a particular individual. There are many types of applications for this, which include physical access entry, logical access entry, the e-passport, and even to a certain extent single-sign-on solutions. The chapter examines applications of facial recognition that have also evolved as well, and include the following: the use of a facial makeup-detection system in facial recognition; thermal face recognition for human-robot interactions; and the use of facial recognition in forensics. It covers the specific concept of eigenfaces. Essentially, eigenfaces are merely a method of confirming the identity of a particular individual based upon the mathematical representations of the unique features of their face.
