TLDR
This correspondence proposes an alternative approach, derived from concepts of fuzzy connectedness, to the hierarchical representation of waveforms based on peak dominance relations, and discusses the possibility of extending this approach to the description of curves and of images.Abstract:
Ehrich and Foith have proposed an approach to the hierarchical representation of waveforms based on peak dominance relations. This correspondence proposes an alternative approach, derived from concepts of fuzzy connectedness. It also discusses the possibility of extending this approach to the description of curves and of images.read more

Understanding Shape: Angles and Sides
TL;DR: Methods of detecting the angles and sides of a simple closed curve are developed that use approximations to the curve that have varying degrees of coarseness, and construct a hierarchy of angles and side that describes the curve at any desired level of detail.
