Mathematical morphology is an important tool of analyzing geometry image. In recent years, morphology has constituted a new image processing method and theory, It has become an important research of computer digital image processing and applied to multi-discipline’s process of digital image analysis and processing. This article’s purposes are understanding the morphological classification, characteristics, application areas and research directions. The second, analyze the definition and functions of four kinds of morphology’s basic operations. These four kinds of operations are:(1)erosion, erosion is the most basic operations of mathematical morphology; (2) dilate, can be seen as the dual operation of erosion;(3) opening operation, which the first erosion than dilate is called open operation; (4) closing operation, which the first dilate than erosion is called close operation. Then, based on Visual C++6.0 use C++ language to develop an image processing system that can process these morphological four kinds of operations in the binary image. Finally,analyze and summarize the functional of these four kinds of operations.Keywords: Mathematical Morphology, Dilation, Erosion, Opening Operation, Closing Operation
