Shape-space from tree-union
Andrea Torsello, Edwin R. Hancock · 2003
In this paper we investigate how to construct a shape space for sets of shock trees. To do this we construct a super-tree to span the union of the set of shock trees. This super-tree is constructed so that it both minimizes the total tree edit distance and preserves edge consistency constraints. Each node of the super-tree corresponds to a dimension of the pattern space. Individual such trees are mapped to vectors in this pattern space.
