WebJan 8, 2013 · It is normally performed on binary images. It needs two inputs, one is our original image, second one is called structuring element or kernel which decides the nature of operation. Two basic morphological operators are Erosion and Dilation. Then its variant forms like Opening, Closing, Gradient etc also comes into play. WebA strel object represents a flat morphological structuring element, which is an essential part of morphological dilation and erosion operations. A flat structuring element is a binary valued neighborhood, either 2-D or multidimensional, in which the true pixels are included in the morphological computation, and the false pixels are not. The ...
WebNov 8, 2013 · Although the presented algorithm is specific to circular structuring elements, it is even easier to apply the basic scheme to horizontal flat structuring elements. In that case, the contact point is examined by checking the highest point (say p 2 in { p 1 , p 2 , p 3 }) between two known contact points (say a , b ).
