Hierarchical Contour Shape Analysis

Daniel Alejandro Valdés Amaro, Abhir Bhalerao


This paper introduces a novel shape representation which performs shape analysis in a hierarchical fashion using Gaussian and Laplacian pyramids. A background on hierarchical shape analysis is given along with a detailed explanation of the hierarchical method, and results are shown on natural contours. A comparisson is performed between the new method and a previously proposed approach using point distribution models with different shape sets. The document concludes with a discussion and proposes ideas on how the new approach may be extended.
