二值图像处理运算是从数学形态学下的集合论方法发展起来的,尽管它的基本运算很简单,但是却可以产生复杂的效果。常用的二值图像处理操作有许多方法,如腐蚀、膨胀、细化、开运算和闭运算等等。本文对这些内容作些研究探讨, 希望对爱好图像处理的朋友有所帮助。(Binary image processing algorithms are developed set theory in mathematical morphology. Although its basic operation is simple, it can produce complex effects. Commonly used binary image processing operations there are many ways, such as corrosion, expansion, refinement, open operation and closed operation and so on. In this paper, some of these studies to explore, I hope to love image processing friends help.)
