Gait Recognition refers to automatic identification of an individual based on his/her style of walking; it's a new biometrics recognition technology. This paper describes a new approach to gait recognition based on kmean clustering algorithm. Body silhouette is extracted by a simple background subtraction, and the clustering is performed to partition image sequence into clusters, so the vectors of feature can be extracted. The recognition is achieved by dynamic time warping technique. We evaluate the proposed gait recognition method on the Gait Challenge database of the University of South Florida (USF), and the experimental results demonstrate that our approach has a good recognition performance.
