2. CAPAIAN PEMBELAJARAN Memahami Operasi Morfologi :
Extraction of Connected Component
Thinning

3. Extraction of Connected Components
Procedure:
Assume that a point p of Y ( a connected component in A) is known.
Following iterative expression yields all the elements of Y.
Xk = (Xk-1  B)  A k = 1,2,3…..
Where X0 =p and B is symmetric structure element
Terminates if Xk = Xk-1

4. Extraction of Connected Components
Find a starting point p in connected
components
Run
where X0=p  Known
when Xk=Xk-1 the algorithm has converged.
k=1,2,3,…

5. Extraction of Connected Components
k=1,2,3,…

-Define in terms of the hit-or-miss transform, denote by:

19. Thinning S B

20. Thinning B

21. Thinning -Define in terms of many structuring elements, denote by
Bi is a rotation version of Bi-1
-The entire process is repeated until no further changes occur
Usually use 8 direction structure elements.
