ABSTRACT
Pose definition The human body can assume various poses. Since it is impossible to collect the data or create template models for all possible poses, it is necessary to define a set of standard, typical poses. A convention for pose definition is yet to be established. One approach is to use joint angle changes as the measures to characterize human pose changes and gross motion. This means that poses can be defined by joint angles. Given a set of scan data, imagery, or photos, the corresponding pose can be determined or identified. Mittal et al (2003) studied human body pose estimation using silhouette shape analysis. Cohen and Li (2003) proposed an approach for inferring the body posture using a 3-D visual-hull constructed from a set of silhouettes.
