A member of the project group (Matej Kristan) coorganized the first challenge in short-term visual tracking VOT2013. The organization committee was international, spreading groups from Slovenia, UK, Austria, Czech Republic and Australia. The challenge was accompanied by a workshop organized at the top computer vision conference ICCV2013. The workshop was well as the challenge were well accepted by the community. Within the challenge, we have compared 27 diverse approaches to tracking of arbitrary, articulated and nonarticulated objects, using a new annotated dataset and new performance evaluation methodology. A paper with the challenge results, coauthored by more than 50 authors, was published and presented at the workshop as an invited talk.
B.01 Organiser of a scientific meeting
COBISS.SI-ID: 10409300We employed our knowledge from the areas of computer architectures and numerical methods in optimization of the oceanographic model North Atlantic Princeton Ocean Model (NAPOM), which has been actively used at the Marine Biology Station in Piran (MBP) and the Slovenian environment agency (ARSO). We analyzed the MBP computer capacities and the current NAPOM software package to identify sections of the program code that were not optimal for their computing hardware. We optimized and parallelized the code, speeding up execution times of the NAPOM simulation package by a factor of 4. We increased the efficiency of the hardware during the calculations and decreased the energy requirements for these calculations. We are performing similar analysis on a larger computing cluster (2000 cores) at the Turboinstitute, with the final goal to reduce the power consumption by 20%.
F.16 Improvements to an existing information system/databases
COBISS.SI-ID: 26332967We have developed a wireless multifunction body sensor for monitoring vital bio-signals. The sensor uses modern, moderately priced and user-friendly technology, with fault-tolerant and robust solutions. It would have an important role in mobile and non-intrusive health monitoring systems. It supports advanced algorithms for local analysis of data and connections to widely available personal terminals for visualization of measurements, and further transfer of critical data, either to medical experts or to a personal database. The sensor is characterized by the fusion of different sensing functions in a single multifunction sensor. To improve the reliability and robustness of the system, measured signals, e.g., ECG, light, voice, acceleration, etc., can be combined in order to prevent the rising of false alarms. We are developing, with medical experts, a diagnostic algorithm that will, based on the measured signals from sensors, issue eventual illness states with corresponding probability. We have demonstrated that such a system can achieve the reliability needed for commercial implementation in applications offering medical care and monitoring services. We have published several contributions from this field in leading conferences and journals.
F.21 Development of new health/diagnostic methods/procedures
COBISS.SI-ID: 26202663Cryotherapy has a beneficial impact on rehabilitation after injury or surgery. However, therapeutic protocols and devices are not standardized, and clinical outcome can therefore not be related accurately to the cryotherapeutic protocols. We implement a study for Wegener, Belgium, to obtain in-vivo data about temperatures of the inner knee parts and to assess the differences between two cryotherapeutic methods: conventional cooling with gel-pack, and computer controlled cryotherapy. The cooling was performed over 12 hours. Temperatures were measured electronically every second for 16 hours after surgery in twenty patients following ACL reconstruction at the University clinical Centre Ljubljana. We have shown that the computer controlled device outperforms the classical method of cooling with its significantly higher effectiveness and its ability to control the heat transfer. We registered an SI patent: "Method and device for non-invasive real-time control of inner temperature variables during cryo or thermo therapy", for which there is already an interest from international industry. The research results are going to be published in a leading journal from the field of knee surgery.
F.22 Improvement to existing health/diagnostic methods/procedures
COBISS.SI-ID: 23557159The book is intended for researchers and practitioners as a foundation of modern parallel computing with several important parallel applications, and for students as a basic or supplementary book for advanced courses on parallel computing. Fifteen chapters, on 519 pages, cover the most important issues of parallel computing, starting from basic principles and continuing with more complex theoretical problems and applications, and to future parallel approaches, including quantum computing. Each chapter is written in two levels - more general overview and more specific theory or practical example. So far, about 1000 samples have been sold, also for pedagogic purposes. According to the Springer statistics the chapters have been downloaded 6630 times, which means that it is one of the top 25% most downloaded eBooks in relevant Springer collection. We have noticed a significant interest for the book on the internet, with several citations beyond those visible in the SICRIS data base. We have edited also another book "Application and Multidisciplinary Aspects of Wireless Sensor Networks", published under the open access policy. According to the Springer statistics, the book was downloaded in the period 2010-2012 1868 times.
