Research on Multi-camera Multi-target Tracking Method Based on Hierarchical Relational Model of Trajectory Tree

open access: yesJisuanji kexue yu tansuo, 2020
To improve the accuracy of camera target tracking, a multi-camera multi-target tracking method based on multi-hypothesis tracking (MHT) framework using hierarchical relation model of trajectory tree is proposed.

On P_4-tidy graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 1997
We study the P_4-tidy graphs, a new class defined by Rusu [30] in order to illustrate the notion of P_4-domination in perfect graphs. This class strictly contains the P_4-extendible graphs and the P_4-lite graphs defined by Jamison & Olariu in [19] and ...

The Clique-Width of Minimal Series-Parallel Digraphs

open access: yesAlgorithms
MSP DAGs (short for minimal series-parallel digraphs) can be defined from the single vertex graph by applying the parallel composition and series composition.

PRYNT: a tool for prioritization of disease candidates from proteomics data using a combination of shortest-path and random walk algorithms

open access: yesScientific Reports, 2021
The urinary proteome is a promising pool of biomarkers of kidney disease. However, the protein changes observed in urine only partially reflect the deregulated mechanisms within kidney tissue.

End Simplicial Vertices in Path Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2016
A graph is a path graph if there is a tree, called UV -model, whose vertices are the maximal cliques of the graph and for each vertex x of the graph the set of maximal cliques that contains it induces a path in the tree.

On r-Noncommuting Graph of Finite Rings

open access: yesAxioms, 2021
Let R be a finite ring and r∈R. The r-noncommuting graph of R, denoted by ΓRr, is a simple undirected graph whose vertex set is R and two vertices x and y are adjacent if and only if [x,y]≠r and [x,y]≠−r.

Tree-width, clique-minors, and eigenvalues

open access: yesDiscrete Mathematics, 2004
Let \(G\) be a simple graph of order \(n\). Let \(\rho(G)\) be the spectral radius of \(G\) and let \(\lambda(G)\) be the least eigenvalue of \(G\). The author proves the following results: If \(G\) is \(K_5\) minor-free graph, then \(\rho(G) \leq 1 + \sqrt{3n - 8}\), where equality holds if and only if \(G\) is isomorphic to \(K_3 \nabla (n-3)K_1 ...

Boundary cliques, clique trees and perfect sequences of maximal cliques of a chordal graph

open access: yes, 2006
We characterize clique trees of a chordal graph in their relation to simplicial vertices and perfect sequences of maximal cliques. We investigate boundary cliques defined by Shibata and clarify their relation to endpoints of clique trees. Next we define a symmetric binary relation between the set of clique trees and the set of perfect sequences of ...
