与单结构元形态滤波相比，多结构元形态滤波能够保护或提取更多的图象几何特征．本文提出了二值图象的多结构元腐蚀、膨胀、开、闭四种多结构元形态滤波器，讨论了四种滤波器的基本性质和滤波性能，并将他们纳入完备网格空间一般形态变换的框架，最后讨论了多结构元形态滤波器的设计． Compared with single structure element morphological filtering, multi-structure element morphological filtering can protect or extract more image geometric features. In this paper, we propose four kinds of multi-structure element morphological filters of multi-structure element corrosion, expansion, open and close, discuss the basic properties and filtering performance of the four kinds of filters, and put them into the general form of complete mesh space Transform the framework, and finally discusses the design of multi-structure element morphological filter.
