Gait recognition
Definition
Gait is defined as the style or manner of walking. Studies in pyschophysics suggest that people can identify familiar individuals using just their gait. This has led to a number of automated vision-based algorithms that use gait as a biometrics. Such a system usually consists of a video camera capturing images of a person walking within its field of view. Appropriate features such as joint angles or silhouettes are extracted from this video and are then used to compare with the stored gait signatures of known individuals. As with any other biometric system, the system can operate in both the identification and the verification mode. Gait as a biometrics has several advantages compared to traditional biometrics such as fingerprint in that gait is nonintrusive, does not require cooperation from the individual, and can function at moderate distances from the subject.
Introduction
The study of human gait has gathered pace in recent years driven...
