A Review of Gait Recognition Techniques and their Challenges

Biometrics in user recognition systems are becoming increasingly important. There are three categories to biometrics namely; physiological, behavioral and token based. Physiological and token based biometrics are widely used in systems that need the user acknowledgement and cooperation for verification, however behavioural biometrics can be used to identify users without their knowledge and cooperation. Gait is a behavioural biometric that distinguishes an individual by the way they walk. Airports, banks and boarder control system could benefit dramatically from such systems. In this paper we look at techniques in model based and holistic approaches used in gait recognition systems. As well as their challenges and open issues.
