A graph is called a triangulated planar graph if it admits a plane embedding in the plane such that all inner faces are triangle. In a rooted triangulated planar graph, a vertex and two edges incident to it are designated as an outer vertex and outer edges, respectively. Two plane embedding of rooted triangulated planar graphs are defined to be equivalent(More)
Given a number n of vertices, a lower bound d on the diameter, and a capacity function ∆(k) ≥ 2, k = 0, 1,. .. , ⌊n/2⌋, we consider the problem of enumerating all unrooted trees T with exactly n vertices and a diameter at least d such that the degree of each vertex with distance k from the center of T is at most ∆(k). We give an algorithm that generates all(More)
Person re-identification refers to recognizing a person in different locations over non-overlapping cameras. This is an important but very challenging problem in intelligent surveillance video analysis areas. In this paper, we proposed a simple yet efficient framework KISSPOP to design a person re-identification system. In this system, we creatively combine(More)
In a rooted graph, a vertex is designated as its root. An outerplanar graph is represented by a plane embedding such that all vertices appear along its outer boundary. Two different plane embeddings of a rooted outerplanar graphs are called symmetric copies. Given integers n ≥ 3 and g ≥ 3, we give an O(n)-space and O(1)-time delay algorithm that enumerates(More)
