In this paper we propose a novel method for discriminative monocular human pose tracking using a mixture of Gaussian processes and a dynamic programming algorithm for selecting the optimal expert at each frame. The proposed tracking mechanism incorporates a dynamical model into the predictive distribution which is combined with the appearance model in a principled manner. This model is able to give a smoother predicted pose and resolves ambiguities in the image to pose mapping. We introduce a

We compare our method to other state of the art methods on 2D and 3D monocular pose estimation on ballet and sign language data sets.
