A deformable and expansible tree for structure recovery
F. Angella, Olivier Lavialle, Pierre Baylou · 2002
This paper presents the use of a deformable and expansible tree as a skeleton extractor. Each node of the tree is a free particle evolving under the repulsive effects of other particles and of the contours. That evolution provides a variable topology and expansible ability properties to the tree. Nodes are simultaneously connected together so that the tree stays inside objects, revealing their hierarchical structure.
