This project explores the use of abstract, physics-based models of
human locomation in tracking. Abstract models, like the one shown
above, are used in robotics and biomechanics to capture key aspects of
the dynamics of human locomotion. Some of them exhibit
humanoid-like walking as passive limit cycles of their motion,
exhibiting their stability and applicability to human motion
modelling. This project aims to use these abstractions to build
motion models which can then be used to constrain human pose tracking.
