New approaches started evolving employing knowledge-based processing though transforming a priori knowledge to low-level models and rules are far from being straightforward. In this paper we examine one of the most popular active contour models snakes and propose a snake model modifying terms and introducing a model-based one that eliminates basic problems through the usage of prior shape knowledge in the model. A probabilistic rule-driven utilization of the proposed model follows being able to handle or cope with objects of different shapes contour complexities and motions different environments indoor and outdoor cluttered sequences and cases where background is complex not smooth and when moving objects get partially occluded. The proposed method has been tested in a variety of sequences and the experimental results verily its efficiency. Keywords and phrases .
