However, Zhao~\etal~\cite{zhao20063d} perform gait recognition in 3-D using multiple cameras. By moving to 3-D, many of the problems related to silhouette extraction and model fitting are removed. Additionally we can take advantage of the wealth of research relating to 3-D motion -capture~\cite{mocap-survey}.
