The system then performs a one-to-one match that compares a query face image against the template face image stored in the database whose identity is being claimed. If a match is made the identity of the person is verified. In other words, the verification test is conducted by dividing the subjects into two groups: • Clients, people trying to gain access using their own identity. e. an identity known to the system but not belonging to them. The percentage of imposters gaining access and clients rejected access are referred to as the False Acceptance Rate (FAR) and False Rejection Rate (FRR) for a given threshold, respectively.
1 Introduction Face recognition is one of the most popular applications in image processing and pattern recognition. It plays a very important role in many applications such as card identification, access control, mug shot searching, security monitoring and surveillance problems. There are several problems that make automatic face recognition a very challenging task. The input of a person’s face to a recognition system is usually acquired under different conditions from those of the corresponding image in the database.
