摘要
本文利用数学形态学（Mathematical Morphology）的有关理论与并行算子及栅格数据处理的方法，提出了一种全自动生成区域间等分界线的快速并行算法，并将此算法推广到n个区域的一般情况。较好地解决了一般方法难以解决的区域轮廓线类型自动划分、等分线起始点的自动寻找及由岛屿和海湾产生的自闭合回路线及支线的自动删除等问题。

According to Mathematical Morphology and its parallel operatores, and also raster processing methods, this paper developed a fast parallel method of producing equidistance line for delimitation of maritime boundary. Based on this method, the algorithms for generation of equidistance lines between a number of aeras also have been presented. Some sophisticated problems, such as delimitation of the types of maritime boundary, finding the begining points of equidistance lines, and deleting the self loop or half loop lines of skeletons, can be solved full-automatically by using the suggested methods. Finally, examples demostrated the principles and efficiency of the presented approach.
