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.)

VC++处理图像模糊或柔化的效果示例源程序,类似Photoshop中的图像高斯模糊效果,每点击一次鼠标右键,程序为模糊一次,直到你满意为止。注意程序仅实现了模糊的功能,其它功能比如程序优化和效率方面的考虑还比较少,因此程序运行速度方面可能会欠缺一些(VC++ deal with image blur or soften the effect of sample source code, similar to Photoshop' s image Gaussian Blur effect, each click the right mouse button, the procedures for fuzzy time until you are satisfied. Note that the program is only vague functions, other functions such as process optimization and efficiency considerations is still relatively small, the speed of the program is running may lack some of the)
