Hierarchical Bag of Paths for Kernel Based Shape Classification
François-Xavier Dupé, Luc Brun
Graph kernels methods are based on an implicit embedding of graphs within a vector space of large dimension. This implicit embedding allows to apply to graphs methods which where u…

Hierarchy construction schemes within the Scale set framework
Jean Hugues Pruvot, Luc Brun
Segmentation algorithms based on an energy minimisation framework often depend on a scale parameter which balances a fit to data and a regularising term. Irregular pyramids are def…

Contains and Inside relationships within combinatorial Pyramids
Luc Brun, Walter G. Kropatsch
Irregular pyramids are made of a stack of successively reduced graphs embedded in the plane. Such pyramids are used within the segmentation framework to encode a hierarchy of parti…
