Texture descriptor based on partially self-avoiding deterministic walker on networks
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012-11-01)
Texture image analysis is an important field of investigation that has attracted the attention from computer vision community in the last decades. In this paper, a novel approach for texture image analysis is proposed by ...
Bisimulations on data graphs
(AI Access Foundation, 2018)
Bisimulation provides structural conditions to characterize indistinguishability from an external observer between nodes on labeled graphs. It is a fundamental notion used in many areas, such as verification, graph-structured ...
Semiautomatic dental recognition using a graph-based segmentation algorithm and teeth shapes features
(2012-10-03)
Dental recognition is very important for forensic human identification, mainly regarding the mass disasters, which have frequently happened due to tsunamis, airplanes crashes, etc. Algorithms for automatic, precise, and ...

Semantic Acyclicity on Graph Databases
(2013)
It is known that unions of acyclic conjunctive queries (CQs)
can be evaluated in linear time, as opposed to arbitrary CQs,
for which the evaluation problem is NP-complete. It follows
from techniques in the area of ...
