Causation principle refers to the relation between the cause or an event and the effect or a second event. The second event is the physical result of the first.      â¦ . Torrey Garcia.
Then the dilation of X by K is simply the set of all points x such that the intersection of Kx with X is non-empty. The mathematical definition of grayscale dilation is identical except for the way in which the set of coordinates associated with the input image is derived.rief Description. Dilation is one of the two basic operators in the area of mathematical morphology, the other being erosion. It is typically applied to binary images, but there are versions that work on grayscale images.
