This chapter presents a survey of the most recent vision-based human body modeling techniques. It includes sections covering the topics of 3D human body coding standards, motion tracking, recognition and applications. Short summaries of various techniques, including their advantages and disadvantages, are introduced. Although this work is focused on computer vision, some references from computer graphics are also given. Considering that it is impossible to find a method valid for all applications, this chapter intends to give an overview of the current techniques in order to help in the selection of the most suitable method for a certain problem.
