Toward a Theory of Statistical Tree-Shape Analysis
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By A. Feragen,P. Lo,M. de Bruijne,M. Nielsen,F. Lauze
Issue Date:August 2013
pp. 2008-2021
To develop statistical methods for shapes with a tree-structure, we construct a shape space framework for tree-shapes and study metrics on the shape space. This shape space has singularities which correspond to topological transitions in the represented tr...
Bicycle chain shape models
Found in: Computer Vision and Pattern Recognition Workshop
By S. Sommer, A. Tatu, Chen Chen, D.R. Jurgensen, M. de Bruijne, M. Loog, M. Nielsen, F. Lauze
Issue Date:June 2009
pp. 157-163
In this paper we introduce landmark-based pre-shapes which allow mixing of anatomical landmarks and pseudo-landmarks, constraining consecutive pseudo-landmarks to satisfy planar equidistance relations. This defines naturally a structure of Riemannian manif...
