IEEE Trans Pattern Analysis and Machine Intelligence,, (): 9-4 Gait-based Human Identification WAG Liang, HU Wei-Ming, TA Tie-iu (ational Laboratory of Pattern Recognition, Institute of Automation, Chinese Academy of Sciences, Beijing, 8) Abstract Human identification at a distance has recently gained more and more interests from computer vision researchers. Gait recognition aims essentially to address this problem by identifying people based on the way they walk. Gait is a particularly attractive modality from a surveillance perspective. In this paper, a simple but efficient motion-based gait recognition algorithm using spatial-temporal silhouette analysis is proposed. For each image sequence, an improved background subtraction algorithm and a simple correspondence procedure are first used to segment and track the moving silhouettes of a walking figure from the background. Then, eigenspace transformation based on the traditional Principal Component Analysis (PCA) is applied to time-varying distance signals derived from a sequence of silhouette images to reduce the dimensionality of the input feature space. Supervised pattern classification techniques are finally performed in the lower-dimensional eigenspace for recognition. This method implicitly captures the structural and transitional characteristics of gait, especially biometric shape cues. Extensive experimental results on outdoor image sequences demonstrate that the proposed algorithm has an encouraging recognition performance with relatively lower computational cost.
