Shape Retrieval using Concavity Trees
y trees are well-known abstract structures. This paper proposes a new shape-based image retrieval method based on concavity trees. The proposed method has two main components. The...

Classification and Constructions of Complete Caps in Binary Spaces
We give new recursive constructions of complete caps in PG(n, 2). We approach the problem of constructing caps with low dependency via the doubling construction and comparison to ...
