| 摘 要： | 空间数据的不确定性是当前GIS领域的研究难点之一。为了描述空间数据的模糊性，把模糊集理论引入GIS，以加强GIS对模糊现象建模的能力，因而产生了模糊数据。但现有GIS缺乏对模糊数据分析和处理的能力。该文把模糊集理论引入数学形态学，提出能处理模糊数据的模糊形态运算，并给出模糊形态运算的隶属函数，使传统的数学形态学能够处理模糊数据且容易在计算机上实现。

| Abstract: | Uncertainty of spatial data is one of the current research issues in GIS domain.In order to enhance the ability of modeling fuzzy phenomena,the fuzzy set theory is introduced into GIS,which produces fuzzy spatial data.However,the current GIS is short of the ability of processing and analyzing the fuzzy data.In this article,the fuzzy set theory is introduced into morphological operations,and fuzzy morphological operations as well as their membership functions that can process fuzzy data are proposed.The fuzzy operations not only enable the morphological operations to process fuzzy data,but also can be easy to be implemented in computer. |
