We propose an active contour model using an external force field that is based on magnetostatics and hypothesized magnetic interactions between the active contour and object boundaries. The major contribution of the method is that the interaction of its forces can greatly improve the active contour in capturing complex geometries and dealing with difficult initializations, weak edges and broken boundaries. The proposed method is shown to achieve significant improvements when compared against six well-known and state-of-the-art shape recovery methods, including the geodesic snake, the generalized version of GVF snake, the combined geodesic and GVF snake, and the charged particle model.
我们提出了一种基于静磁学的外力场主动轮廓模型，并假设了主动轮廓与物体边界之间的磁相互作用。该方法的主要贡献在于其力的相互作用能够在捕捉复杂几何形状以及处理困难的初始化、弱边缘和断裂边界时极大地改进主动轮廓。与六种著名的、当前最先进的形状恢复方法相比，包括测地线蛇形模型、广义GVF蛇形模型、组合测地线和GVF蛇形模型以及带电粒子模型，所提出的方法显示出显著的改进。
