OpenCV: More Morphology Transformations

In mathematical morphology, the closing of a set (binary image) A by a structuring element B is the erosion of the dilation of that set, where and denote the dilation and erosion, respectively. In image processing, closing is, together with opening, the basic workhorse of morphological noise removal. Opening removes small objects, while closing re… WebMorphological opening & closing (图像形态学开运算和闭运算) 都属于 spatial filtering （空间滤波）的操作。大体上来讲，开运算往往能够移除图像中较为孤立的点，并且加大图形之间的间隙；而闭运算恰恰相反，往往能够增加图形之间的联系（使得间隙缩小或消失）。 Web8 de jan. de 2013 · Here we discuss briefly 5 operations offered by OpenCV: Opening It is obtained by the erosion of an image followed by a dilation.
