Early and Late Fusion of Classifiers for the MediaEval 2018 Medico Task

AAU/ITEC researchers Mario Taschwer, Klaus Schöffmann, and Jürgen Primus collaborated with Oge Marques (FAU, USA) on a research challenge targeting automatic classification of endoscopic images of the human gastro-intestinal tract. The challenge was posed as the MediaEval 2018 Medico task and called not only for classification effectiveness, but also for run-time efficiency of proposed approaches. The joint AAU-FAU team therefore proposed a combination of CNN-based feature extraction with traditional machine learning algorithms and achieved respectable results in comparison to deep-learning based approaches submitted by other participants, which has been honored with a “distinctive mention” by Medico task organizers. The AAU-FAU approach has been presented remotely by Mario Taschwer at the MediaEval 2018 Workshop, Sophia Antipolis, France, on October 30, 2018.

Klaus Schöffmann, Bernd Münzer & Sabrina Kletz @ ACM International Conference on Multimedia in Seoul, South Korea

,

From October 22-26, 2018, Klaus Schöffmann and people from his group (Sabrina Kletz and Bernd Münzer) participated in the ACM International Conference on Multimedia in Seoul, South Korea. Klaus Schöffmann presented two well-attended tutorials – one on “Interactive Video Search“ together with colleagues from Prague University, JOANNEUM RESEARCH, and NIST – and another one on “Medical Multimedia” together with Bernd Münzer and colleagues from Simula Research (the slides for both tutorials can be found below). Moreover, Sabrina Kletz successfully presented her PhD work there in the Doctoral Consortium and received some feedback from the community.

Philipp Moll

Philipp Moll presented his paper on “Wireless Network Emulation for Research on Information Centric Networking” at the ACM WiNTECH Workshop 2018.

The WiNTECH workshop explicitly deals with methodological and technical issues that have to be faced for defining, running, controlling and benchmarking experiments on wireless solutions. The workshop, that this year reach the 12th edition, has a consolidated tradition for bringing together an important number of researchers and industry players working in different aspects of experimental wireless communications. This year the workshop was held in conjunction with the International Conference on Mobile Computing and Networking (MobiCom) in New Delhi, India. Read more

Philipp Moll’s Research Stay at UCLA

During the summer break, Philipp Moll was visiting his Mentor Jeff Burke at the University of California, Los Angeles (UCLA). The main focus of the stay was to progress the dissertation project, which is about Gaming over Named Data Networking. During the stay, Philipp Moll worked together with researchers from two different research groups from UCLA, Jeff Burke’s Center for Research in Engineering, Media and Performance (REMAP) and Lixia Zhangs Internet Research Lab (IRL). Together with Jeff Burke, the decision was made to use Minecraft to build a prototype for a distributed game architecture with NDN as network protocol. Finally, a network protocol for that architecture was designed, which is now the base for future publications.

Currently, the prototype of Minecraft over NDN is build at AAU. One part of the prototype, the synchronization of the game state among multiple game servers, is currently developed in the course of a master thesis under the supervision of Prof. Hermann Hellwagner and Philipp Moll.

Klaus Schöffmann on the PhD defense committee of Luca Rossetto and gives an invited talk about “Medical Video Analytics”.

On September 27, 2018 Klaus Schöffmann participated on the PhD defense committee of Luca Rossetto at the University of Basel. The title of Luca Rossetto’s PhD is “Multi-Modal Video Retrieval”. Additionally, he gave an invited talk on September 28, 2018 about “Medical Video Analytics at the University of Basel, Department of Mathematics and Computer Science.

ITEC researchers presenting at 25th IEEE International Conference on Image Processing (ICIP) in Athens, Greece on October 7-10, 2018

,

The 25th IEEE International Conference on Image Processing (ICIP; https://2018.ieeeicip.org/) will be held in Athens, Greece on October 7-10, 2018. ITEC researcher Anatoliy Zabrovskiy will present “A Practical Evaluation of Video Codecs for Large-Scale HTTP Adaptive Streaming Services” within the special session on “Video Coding at Scale”. The abstract is as follows: The number of bandwidth-hungry applications and services is constantly growing. HTTP adaptive streaming of audiovisual content accounts for the majority of today’s internet traffic. Although the internet bandwidth increases also constantly, audio-visual compression technology is inevitable and we are currently facing the challenge to be confronted with multiple video codecs. This paper provides a practical evaluation of state of the art video codecs (i. e., AV1, AVC/libx264, HEVC/libx265, VP9/Iibvpx-vp9) for large-scale HTTP adaptive streaming services. In anticipation of the results, AV1 shows promising performance compared to established video codecs. Additionally, AV1 is intended to be royalty free making it worthwhile to be considered for large scale HTTP adaptive streaming services. Read more
