6 : Discussions and Conclusions
In this paper, we proposed a new shape decomposition method which extended
the morphological methods. It can conquer two problems for the current
morphological methods, scale invariant and noise. We have proposed a
graph Laplacian energy based hierarchy shape decomposition.We can extract
more stable graph structure by using our methods. Our next step is to use
these graph structures to do shape analysis. One possible way is to combine
the spectral graph invariants [17] for shape recognition. Recently, Trinh and
Kimia [13] has proposed a graph generative for shape through the analysis of
shock graphs. We can also extend our methods with graph generative model
for morphological decomposition.
