VALDES-AMARO, Daniel  e  BHALERAO, Abhir. Hierarchical Contour Shape Analysis. Comp. y Sist. [online]. 2015, vol.19, n.2, pp.233-242. ISSN 2007-9737.  https://doi.org/10.13053/CyS-19-2-1935.

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 comparison is performed between the new method and our proposed approach using Point Distribution Models with different shape sets. The paper concludes with a discussion and proposes ideas on how the new approach may be extended.

Palavras-chave : Shape analysis; shape representation; Gaussian pyramids; shape models; brain contours.
