An Analytical Survey on Face Recognition Systems
Among various biometric techniques, face recognition is the most popular and widely used technology. It is less
expensive, natural and more effective as compared to other techniques. The face recognition techniques can be divided into
various categories. Some techniques use whole face for detection while others use only some features of the face. In this
paper, we present an analytical survey on different face detection methods. A comparative study between different methods
has been provided. We have also analyzed the use of face recognition system as an identification tool. A comprehensive
survey with detailed explanationsof various methods within each category has been provided.
