Geometric algebra for pose estimation and surface morphing in human motion estimation


by Rosenhahn, B and Klette, R
Abstract:
We exploit properties of geometric algebras (GAs) to model the 2D-3D pose estimation problem for free-form surfaces which are coupled with kinematic chains. We further describe local and global surface morphing approaches with GA and combine them with the 2D-3D pose estimation problem. As an application of the presented approach, human motion estimation is considered. The estimated joint angles are used to deform surface patches to gain more realistic human models and therefore more accurate pose estimation results. © Springer-Verlag 2004.
