Dilation (morphology)
Dilation is one of the basic operations in mathematical morphology. Originally developed for binary images, it has been expanded first to grayscale images, and then to complete lattices. The dilation ...

Watershed (image processing)
In the study of image processing a watershed of a grayscale image is analogous to the notion of a catchment basin of a heightmap. In short, a drop of water following the gradient of an image flows alo...
