Abstract

Gait enjoys advantages over other biometrics in that it can be perceived from a distance and is difficult to disguise. Current approaches are mostly statistical and concentrate on walking only. By analysing leg motion we show how we can recognise people not only by the walking gait, but also by the running gait. This is achieved by either of two new modelling approaches which employ coupled oscillators and the biomechanics of human locomotion as the underlying concepts. These models give a plausible method for data reduction by providing estimates of the inclination of the thigh and of the leg, from the image data.
Both approaches derive a phase-weighted Fourier description gait signature by automated non-invasive means. One approach is completely automated whereas the other requires specification of a single parameter to distinguish between walking and running. Results show that both gaits are potential biometrics,with running being more potent. By its basis in evidence gathering, this new technique can tolerate noise and low resolution.
