Thinning Operator


This morphological operator is the subtration betwen the input image and the sup-generating operator with structuring elements A and B. The result is the original image but with pixels which center contains the pattern specified by A and B marked as zero. This operation removes pixels which satisfies the pattern given by the structuring elements A and B.

In this example, the image is thinned by removing isolated 4-connected pixels. The pattern used is:

    000        010                .0.
A = 010    B = 101  <=> Pattern = 010 
    000        010                .0.
So:

Sup-Gen(A,B) =

Original ~ Sup-Gen =
