Abstract

Vision-based human pose estimation is useful in pervasive computing. In this paper, we proposed an example-based approach to human pose estimation from monocular image sequences. We use human motion capture data to synthesize a pose example database with each pose's 3D information known. Firstly, we use shape context to describe the human silhouette detected from video frames, and get candidates from the pose database by silhouette matching; Secondly, we build probability and statistical model of motion, and carry out pose estimation from these candidates; Finally, Kernel Regression is used to smooth the motion. The proposed method could effectively analyze 3D pose from video and solve the orientation ambiguities problem, also it is invariant to view points. The effectiveness of this method is verified on videos of walking, running and jumping.
