Pose estimation for human-robot interaction

Human-robot interaction using gesture recognition typically requires that the 3D pose of a human be tracked in real time, but this can be challenging, particularly when only a single, potentially moving, camera is available. We use a mixture of random walks model for human motion that allowed for fast Rao-Blackwellised tracking, and provide a useful mechanism to map from 2D to 3D pose when only a few joint measurements were made.

Pose estimation code is available here and here. As a useful byproduct, a simplified motion model proves quite effective at estimating missing marker positions for motion capture applications. Code is available here.
