Gait recognition is the process of identifying an individual by the manor in which they walk. This is a marker less unobtrusive biometric, which offers the possibility to identify people at a distance, without any interaction or co-operation from the subject, this is the property which makes it so attractive as a method of identification.

The interest in gait as a biometric is strongly motivated by the need for an automated recognition system for visual surveillance and monitoring applications. Recently, the use of gait for people identification in surveillance applications has attracted researchers from computer vision. The suitability of gait recognition for surveillance systems emerges from the fact that gait can be perceived from a distance as well as its non-invasive nature. Although gait recognition is still a new biometric, it overcomes most of the limitations that other biometrics suffer from such as face, fingerprints and iris recognition which can be obscured in most situations where serious crimes are involved.

We have developed a fast and accurate algorithm for gait recognition based on spatio-temporal statistical distribution of pixels present in silhouettes images. Code has been tested on CASIA Gait Database. Input frames are processed and extracted feature vectors are used to train a neural network.
