A Brief Introduction of Face Recognition

Abstract

Image, or image sequence, have been significantly accessible due to fast pace of device development. Based on that, branches of appliance in recognition especially face recognition emerged, and have been contributing a lot to human security and privacy. This paper demonstrates a brief introduction of face recognition. To begin with, main steps are represented with an overall explanation. After that, in each specific step several outstanding algorithms are offered, followed by their performance in different platform. Finally, widespread face databases are demonstrated, along with detailed information and description of each.
