... B, is the set of all points obtained by adding the points of B to the points in the underlying point
set of the black pixels. An erosion can be obtained by dilating the complement of the black ... transformation that combines two sets by using vector addition of set elements.
In particular, a dilation of the set of black pixels in a binary image by another set (usually c...
