Hyunjin Yoo: Image based reflectance analysis   Abstract: In this talk, the BRDF measurement system is presented. For many years, texture mapping or vertex colors have been widely used to represent an appearance of the object in many applications. However, most materials require physical reflectance properties to appear more realistic. We built systems that can measure Bidirectional Reflectance Distribution Function (BRDF) of opaque materials. Specially, the research on color characterization method of high dynamic range imaging (HDRI) system for BRDF acquisition system is introduced.   CV: Hyunjin Yoo received the M.S. degree in Information and Communications and the Ph.D. degree in Information and Mechatronics from the Gwangju Institute of Science and Technology (GIST), Gwangju, Korea, in 2005 and 2011, respectively. She is currently a PostDoc Researcher in Faculty of Informatics, Vienna University of Technology. She was an intern in Microsoft Research Asia at Beijing(Aug. 2007 ~ Feb. 2008). She worked as a senior researcher at Convergence laboratory, CTO, LG electronics from 2011-2012. Her main interests lie in HDRI, color device characterization, BRDF, computer vision/graphics, and computational photography.

Speaker: Dalia Kriksciuniene, Assoc.prof.dr. (ERCIM researcher at Masaryk University, Brno, Czech) Title: Anomaly detection methods and applications Abstract: Numerous statistical, econometrical and intelligent methods are researched in the scientific works and industrial applications for finding repeating patterns and approximated distribution rules of data series. The main problem experienced by the scientific research is lack of regularities and rather chaotic nature of real data. That hinders performance of the forecasting methods based on finding regularities in data distribution, limits their application to analytics of historical data repositories, and reveals high unreliability of the models to react to occurring external impacts for real-time data streams.  The current research aims to explore application of computational analysis methods for detecting behaviour anomalies. The methods and the principles of anomaly detection are analysed from the theoretical perspective and evaluated for their ability to serve for analysis, forecasting and designing optimal strategies for the enterprises operation in various application domains.  They include analysis of anomalies of the financial markets, caused by changes of investor activeness due to different calendar effects, impacts of various media announcements and news, fluctuations of market situations, including crises and bubbles. The anomaly detection is important in the areas of facility management based on sensor data system, detection of network intrusions and performance failures. The results of currently published research cover several methods for detecting behaviour anomalies including information efficiency evaluation methods (Shannon's entropy, Hurst exponent), event impacts explored by the methods of interrupted time series, and evaluation of binary clustering algorithms. The research results are evaluated by discussing the potential power of explored methods for detection behaviour anomalies in the expanding research area of Big Data.

Invent a Chip/AT ist ein Wettbewerb für technikbegeisterte Schüler, die in die Welt der Technik und Chipentwicklung eintauchen und eigene Chip-Ideen realisieren möchten. Basierend auf dem seit mehr als einem Jahrzehnt in Deutschland durchgeführten gleichnamigen Wettbewerb, ist die österreichische Initiative von OVE, TU Wien, JKU und weiteren Partnern ins Leben gerufen worden. Nach einem sehr erfolgreichen Start geht Invent a Chip in Österreich 2012 in seine nunmehr dritte Runde.
