Abstract

In recent years Sequential Monte Carlo (SMC) methodshave been applied to handle some of the problems inherentto model-based tracking. In this paper two issues regardingSMC are investigated in the context of estimating the3D pose of the human arm. Firstly, we investigate how toapply a sub-space to representing the pose of a human armmore efficiently, i.e., reducing the dimensionality. Secondly,we investigate how to apply a local method to estimated themaximum a posteriori (MAP). The former issue is based oncombining a screw axis representation with the position ofthe hand in the image. The latter issue is handled by applyinga method based on maximising a proximity function, toestimate the MAP. We find that both the sub-space and theproximity function are sound strategies and that they are animprovement over the current SMC-methods.
