摘要： 为了改进主动轮廓线模型求解过程中轮廓线初始位置的敏感性,通常要采用一些方法扩大图像力的作用域。但是,这些方法往往需要根据具体场合来设计,没有比较好的普适性,而且在扩大作用域的过程中不能很好地控制作用域的大小。文章提出一种作用域扩展函数,既能方便地应用于各种需要扩展图像力作用域的场合,还能够控制图像力的作用范围。

Abstract: To improve the active contour model's sensitivity to its initial position, some methods must be applied to widen the image force scope. However, these methods should be designed for the specific case, and the size of the scope can't be controlled in the widening. The article establishes a scope-widen function for a general application with the feature of control over the image force scope.
