Automatic Gait Recognition

Abstract

Gait is “a manner of walking “. Human gait is a feature of a person that is determined by his weight, limb length, and habitual posture. Gait can be used as a biometric measure to recognize known persons. An Automatic Gait recognition system is a computer application for automatically identifying or verifying a person from a digital image or a video frame from a video source. It is a process where, given still or video images of a scene, identify or verify one or more persons in the scene using a stored database of Silhouettes. It is non- contact, unobtrusive perceivable at a distance and hard to disguise. Automatic Gait recognition system could allow law enforcement agencies and airport security to recognize suspects based on the way they were, their characteristic gait. The gait of individuals checking in at an airport could then be compared with the database, perhaps even before they enter the airport concourse. Such data compared with CCTV footage might also be used to track suspect terrorists or criminals who may otherwise be disguising their features or be carrying forged document.
