Abstract
In recent years, several techniques have been proposed which integrate face, a physical biometric, with gait, a behavioral biometric, with the aim of investigating if such a combination will improve upon the performance of methods which exclusively employ only one of these biometrics. An overview of some of the well-known approaches in this area, along with a discussion of the advantages offered and the challenges faced by such systems, is provided in this paper and the potential of this technology for further research and application is explored.
