Segmentation of Curvilinear Objects Using a~Watershed-Based Curve Adjacency Graph
Abstract. This paper presents a general framework to segment curvilinear objects in 2D images. A pre-processing step relies on mathematical morphology to obtain a connected line wh...

On the Existence and Determination of Satisfactory Partitions in a Graph
The Satisfactory Partition problem consists in deciding if a given graph has a partition of its vertex set into two nonempty sets V1, V2 such that for each vertex v, if v ∈ Vi th...

Enumerating Spanning and Connected Subsets in Graphs and Matroids
We show that enumerating all minimal spanning and connected subsets of a given matroid is quasi-polynomially equivalent to the well-known hypergraph transversal problem, and thus ...

One-to-many node-disjoint paths in (n, k)-star graphs
We present an algorithm which given a source node and a set of n - 1 target nodes in the (n, k)-star graph Sn,k, where all nodes are distinct, builds a collection of n - 1 node-di...
