Using Artificial Vision Techniques for Individual Player Tracking in Sport Events
(M D P I AG, 2019-07-31)
[Abstract] We introduce a hybrid approach that can track an individual football player in a video sequence. This solution achieves a good balance between speed and accuracy, combining traditional object tracking techniques ...
Efficient Culling Techniques for Interactive Deformable NURBS Surfaces on GPU
(SciTePress, 2016-02)
[Abstrtact] InfoValue: NURBS (Non-uniform rational B-splines) surfaces are the standard freeform representation in Computer-Aided Design (CAD) applications. Rendering NURBS surfaces accurately while they are interactively ...
Communication avoiding and overlapping for numerical linear algebra
(IEEE Computer Society, 2013-02-25)
[Abstract] To efficiently scale dense linear algebra problems to future exascale systems, communication cost must be avoided or overlapped. Communication-avoiding 2.5D algorithms improve scalability by reducing inter-processor ...
Texture Mapping on NURBS Surface
(M D P I AG, 2018-09-17)
[Abstract] Texture mapping allows high resolution details over 3D surfaces. Nevertheless, texture mapping has a number of unresolved problems such as distortion, boundary between textures or filtering. On the other hand, ...
Synthesis of Multiresolution Scenes with Global Illumination on a GPU
(SciTePress, 2012-02)
[Abstract] The radiosity computation has the important feature of producing view independent results, but these results are mesh dependent and, in consequence, are attached to a specific level of detail in the input mesh. ...
In-Transit Molecular Dynamics Analysis with Apache Flink
(Association for Computing Machinery (ACM), 2018-11)
[Abstract] In this paper, an on-line parallel analytics framework is proposed to process and store in transit all the data being generated by a Molecular Dynamics (MD) simulation run using staging nodes in the same cluster ...
Free adaptive tessellation strategy of bézier surfaces
(SciTePress, 2014-01)
[Abstract] Rendering of Bézier surfaces is currently performed by tessellating the model on the GPU and rendering the highly detailed triangle mesh. Whereas non-adaptive strategies apply the same tessellation pattern to ...
Extending the Globus Information Service with the Common Information Model
(IEEE Computer Society, 2011-07-14)
[Abstract] The need of task-adapted and complete information for the management of resources is a well known issue in Grid computing. Globus Toolkit 4 (GT4) includes the Monitoring and Discovery System component (MDS4) to ...
Parallelization of ARACNe, an Algorithm for the Reconstruction of Gene Regulatory Networks
(M D P I AG, 2019-07-31)
[Abstract] Gene regulatory networks are graphical representations of molecular regulators that interact with each other and with other substances in the cell to govern the gene expression. There are different computational ...
Evaluation of Parallel Differential Evolution Implementations on MapReduce and Spark
(Springer, 2017-09)
[Abstract] Global optimization problems arise in many areas of science and engineering, computational and systems biology and bioinformatics among them. Many research efforts have focused on developing parallel metaheuristics ...
