针对静磁力主动轮廓模型计算复杂度较高,收敛速度较慢的问题.将该模型对应的水平集方程做隐式数值化,采用加性算子分割方法(AOS)求解.实验发现,这种改进后的静磁场主动轮廓模型不仅保留了原有模型的优点,而且提高原有模型的收敛速度和稳定性.%In order to reduce the computation complexity, accelerate the convergence ot the magnetostatic active contour model, an implicit discretization is proposed for the level set equation of the model and it is solved using Additive Operator Splitting scheme (AOS). Experiments show that the proposed scheme not only keeps the advantages of original model, but also increases the convergent velocity and stability.
