The Basic Morphologic Trasformation and Structuring Element Decomposing of Digital Map Image

This paper is a part of the research result of mathematical morphology, digital image analysis and recognition of the map. The paper presented a new concept of map graph subset and the principle determining basic element of morphologic analysis of map image, and proved a minimun decomposing theorems of basic element of structuring element. The basic morphologic transformation is also introduced, and the mathematical morphlology transformation model with control conditions are also unified and expanded. Then, the mathematical basis for digital map image analysis and recognition is established.
