PM-AM is a system for automatic acquisition of the human body model and tracking of its parameters using input from multiple synchronized video streams. The video frames are segmented and the 3D voxel reconstructions of the human body shape in each frame are computed from the foreground silhouettes. These reconstructions are then input to the model acquisition and tracking algorithms. 

Model acquisition uses a Bayesian network to estimate human body part sizes:

The tracker is an extended Kalman filter that estimates model parameters based on the measurements made on the labeled voxel data:
