Abstract :
In this paper, the optimal method of active-surface and level set segmentation is analyzed then a novel approach to joint space-time is presented, which simplifies the problem into an interactive estimation of motion parameters and segmentation surface. The model is formulated and then scattered using Fast Marching Method. Finally, these two-frame and multiple-frame methods are evaluated and compared by examples; the results show that the later method has higher authenticity.
