Abstract
In the field of human motion analysis, recovering 3D human postures from image sequence may encounter many difficult issues due to the little understanding of how visual mechanisms works. This topic has motivates increasing interests among image processing researchers. In this paper, a method of recovery of 3D human posture from single view is proposed. The recovery process is as follows: First, the image sequences of human motion are acquired by single camera. The body region is extracted from the image by background subtraction, and body silhouette is represented by FCC(Freeman Chain Code); then each part of the body is labeled, and the coordinates of joints connecting the body parts are retrieved. Thus the sequence of 2D human skeletons is recovered from the image sequence. At last, 3D human skeleton can be recovered by perspective projection model of the camera and knowledge about human structure. This paper gives the tracking results for three different kinds of human motion. The 3D human skeletons can be successfully retrieved in the whole course ofthe complex movement. This proves that the system have certain advantages and fascinating applications. It is a basic and important step toward the recognition of human motion.
