Motion analysis of human ambulatory patterns

Studying the visual motion of human ambulatory patterns is of great importance for both vision research and applications. The authors first present three new algorithms for the recovery of three-dimensional structures from the motion of certain types of joints of articulated objects assuming perspective projection. Then based on the assumption that a human body can be considered as an articulated object and each part of the articulated object is rigid, they apply these algorithms to motion analysis of human ambulatory patterns in a combined way. The proposed algorithms have been tested in terms of the uniqueness of real solution and the speed of convergence using the synthesized data
