Abstract. Hidden State Shape Models (HSSMs) were previously pro­
posed to represent and detect objects in images that exhibit not just
deformation of their shape but also variation in their structure. In this
paper, we introduce Dynamic Hidden­State Shape Models (DHSSMs)
to track and recognize the non­rigid motion of such objects, for exam­
ple, human hands. Our recursive Bayesian filtering method, called DP­
Tracking, combines an exhaustive local search for a match between
image features and model states with a dynamic programming approach
to find a global registration between the model and the object in the
image. Our contribution is a technique to exploit the hierarchical struc­
