Thickning Operator


This morphological operator is the union of the input image and the sup-generating operator with structuring elements A and B. The result is the original image with additional pixels in the places where the pattern specified by A and B is satisfied. This operation thicken the image in the places where the pattern given by the structuring elements A and B is satisfied.

In this example, the image is thickened by removing isolated 8-connected holes. The pattern used is:

    111        000                111
A = 101    B = 010  <=> Pattern = 101 
    111        000                111
So:

Sup-Gen(A,B) =

Original U Sup-Gen =
