Abstract. In this paper, we proposed a fast and accurate human pose
estimation framework that combines top-down and bottom-up methods.
The framework consists of an initialization stage and an iterative search-
ing stage. In the initialization stage, example based method is used to
find several initial poses which are used as searching seeds of the next
stage. In the iterative searching stage, a larger number of body parts can-
didates are generated by adding random disturbance to searching seeds.
Belief Propagation (BP) algorithm is applied to these candidates to find
the best n poses using the information of global graph model and part
image likelihood. Then these poses are further used as searching seeds
