6.3. STUDY OF EWT PROPERTIES 89 (a) (b) Figure 6.15: (a) Original Lena image. (b) Opened by reconstruction image using SE of 3x3. 6.3 Study of EWT properties What are the properties of extrema watershed tree and why use it? The EWT has two main properties, listed below: 1. This tree representation is self-dual. 2. The Extrema watershed tree provides implicit hierarchical segmentation due to the following reasons: • A tree is created in watershed-like process. • Small area extrema are leaves. • Bigger flat zones are close to the root. • Vertices connected in the tree usually have similar gray levels. 6.3.1 Implicit segmentation Recalling that the extrema-watershed tree is built in a process that is very similar to flooding, it is natural to investigate the potential of using the resulting tree for
