摘要
在等值线图的基础上，引入α边界概念，通过各区域舍弃一些隶属度较小的元素使模糊边界压缩，甚至缩为一条等值曲线，研究了二维模糊分类图形的模糊边界及确定此类边界的方法。给出了在绘制交通状况时间—空间分布图形中的应用实例。
On the basis of contour maps, this paper studies the fuzzy boundaries in 2D fuzzy classification maps, presents a method to define the boundaries and puts forword the concept of α boundary. It means that the fuzzy boundaries can be compressed, even becomes a contour, so logn as each set abandons some elements with little membership. As a practical example, it is discussed to draw the time space fuzzy distribution map of traffic situations on freeways.
