Chapter 5<br />
Tree Semilattices<br />
In this chapter, we propose a general framework for tree-based morphological image<br />
processing, which unifies the schemes presented in previous chapters, and enables the<br />
definition of new morphological operators that are based on tree representations. The<br />
heart of the proposed approach is a novel complete inf-semilattice of tree representa-<br />
tions of images. The proposed image processing scheme is shown is figure 5.1.<br />
This chapter is organized as follows. First, Section 5.1 introduces the complete<br />
inf-semilattice of tree representations. Then, in Section 5.2, morphological image<br />
processing using the complete inf-semilattice of tree representations is developed. In<br />
Section 5.3, we address the problem of whether the complete inf-semilattice of tree<br />
representations induces a complete inf-semilattice structure on the set of images as<br />
well. Finally, the chapter is summarized in Section 5.4.<br />
