Biometrics have been used for human verification and identification for decades. Popular human biometrics are face, fingerprint, and iris. They are effectively used in real applications under a controlled environment. Many external factors are controlled, such as lighting condition, distance to a camera, not wearing hat and sunglasses, viewing angles, and requesting physical contact. However, with these constraints, existing approaches could not be used for a purpose of automatic surveillance monitoring, where human are captured through a surveillance camera from a far distance, under any seen angles, and without any physical contact. This becomes main challenges of this research project. Thus, this project develops a new system using an alternative biometric solution using human gait.

Currently, it could achieve a perfect accuracy of 100%, but under a controlled environment and a fixed walking condition. This is not feasible to be used in a real-world scenario. This project, therefore, focuses on solving challenges of gait recognition under changes of internal and external factors such as camera viewing angles, walking directions, and walking speeds. This will make the gait-based human identification more practical to be used in real-world scenarios.
