Abstract

In real monitoring circumstances ， pedestrians ’ front-view gaits are more common than lateral-view ones. As the existing gait recognition methods are mainly focused on lateral-view gaits instead of front-view gaits ，a new front-view gait recognition method on the basis of automatic perspective conversion is proposed according
to the statistics of pedestrians ’ gait features. Through calculating pedestrians ’ gait energy images ， walking
trajectories and gait view angles ， this method extracts and recognizes gait features under the same view angle
after the transformation of view angles. Experimental results show that the proposed method works well under
real monitoring circumstances when the parameters of monocular camera are unknown ， and that it achieves a
recognition rate for front-view gait of 81% and an identified frame number of 21 per second.

Key words： gait recognition; biological recognition; gait energy image; view invariant; feature extraction
