Modelling postures of human movements

The goal of this paper is to present a novel modelling of postures of human activities such us walk, run... Effectively, human action is, in general, characterized by a sequence of specific body postures. So, from an incoming sequence video, we determine the postures (key-frames) which will represent the movement. We construct the prototypes corresponding to these key-frames by thinning these postures, and then we use this skeleton as a starting point for building the model. Some results are presented to validate our models.
