Deimel, Raphael; Brock, Oliver (2016-03-31)

This dataset contains the CAD models for creating a RBO Hand 2. It consists of a set of molds that can be printed and used to create Pneuflex actuators, and a scaffold to attach actuators to in ord...

Simultaneous Acquisition of EEG and NIRS during Cognitive Tasks for an Open Access Dataset

Shin, Jaeyoung; von Lühmann, Alexander; Kim, Do-won; Mehnert, Jan; Hwang, Han-Jeong; Müller, Klaus-Robert (2017)

We provide an open access multimodal brain-imaging dataset of simultaneous electroencephalography (EEG) and near-infrared spectroscopy (NIRS) recordings. Twenty-six healthy subjects performed three...

Affective analysis of videos

Acar Celik, Esra (2017)

As the amount of available multimedia content becomes more and more abundant, the use of automatic multimedia analysis solutions in order to find relevant semantic search results or to identify ill...

Quality of experience of multiparty conferencing and telemeeting systems

Skowronek, Janto (2017)

Die vorliegende Dissertation behandelt die Qualitätswahrnehmung von Telemeetingsystemen, d.h. audiovisuellen Telekonferenzsystemen, bei denen mehr als zwei Gesprächspartner miteinander verbunden si...

Strukturvariabilität in der objektorientierten Modellierung und Simulation durch Generierung von Varianten

Gómez Esperón, Daniel (2017)

In Forschung und Entwicklung wird die Modellierung von technischen Systemen als Ergänzung oder als Ersatz für klassische Prototypen verwendet. Die Simulation ist die Ausführung eines solchen Softwa...

GPGPU workload characteristics and performance analysis

Lal, Sohan; Lucas, Jan; Andersch, Michael; Álvarez-Mesa, Mauricio; Elhossini, Ahmed; Juurlink, Ben (2014)

GPUs are much more power-efficient devices compared to CPUs, but due to several performance bottlenecks, the performance per watt of GPUs is often much lower than what could be achieved theoretical...

Nexus#: a distributed hardware task manager for task-based programming models

Dallou, Tamer; Engelhardt, Nina; Elhossini, Ahmed; Juurlink, Ben (2015)

In the era of multicore systems, it is expected that the number of cores that can be integrated on a single chip will be 3-digit. The key to utilize such a huge computational power is to extract th...

Low-complexity VBR controller for spatial-CGS and temporal scalable video coding

Sanz-Rodríguez, Sergio; Díaz-de-María, Fernando; Rezaei, Mehdi (2009)

This paper presents a rate control (RC) algorithm for the scalable extension of the H.264/AVC video coding standard. The proposed rate controller is designed for real-time video streaming with buff...

Improving the parallelization efficiency of HEVC decoding

Chi, Chi Ching; Álvarez-Mesa, Mauricio; Juurlink, Ben; George, Valeri; Schierl, Thomas (2012)

In this paper we present a new parallelization approach for HEVC decoding called Overlapped Wavefront (OWF). It is based on wavefront processing and improves its parallelization efficiency by allow...

Low-complexity motion-based saliency map estimation for perceptual video coding

Mejía-Ocaña, Ana Belén; de-Frutos-López, Manuel; Sanz-Rodríguez, Sergio; del-Ama-Esteban, Óscar; Peláez-Moreno, Carmen; Díaz-de-María, Fernando (2011)

In this paper, a low-complexity motion-based saliency map estimation method for perceptual video coding is proposed. The method employs a camera motion compensated vector map computed by means of a...
