In this paper, we propose the Active Net model and its application to region extraction. Active Net is a simulated two dimensional elastic network model which minimizes the energy functional and therefore shows both active and dynamic behavior. Its energy functional consists of the internal strain energy of the net and the image energy which attracts the net to features in a target region. The net deforms to wrap the region as the energy functional is minimized. We can apply Active Net to the extraction of a textured region. Some experimental results are also described.
