Digital images have become omnipresent in modern life. The popularity and affordability of handheld imaging devices, especially smartphones, along with the rapid development of social media and social networking services such as Facebook, Flickr, and Instagram have made images a popular and integral part of everyday communication. With the development of visual media transmission systems, it is becoming increasingly important to improve visual applications in order to meet the quality expectations of end users. For this aim, it is important to evaluate the image quality directly from the user’s perspective, which is known as quality of experience.
I’m a PhD student at University of Ontario Institute of Technology (UOIT) in Canada, where I belong to the visualization for information analytics laboratory (vialab). In this past summer, I had the amazing opportunity to spend 3 months in the University of Konstanz working closely with the Data Analytics and the Computational Linguistic groups.
Last week (October 8-12, 2018) was a conference week for computer scientists in Stuttgart, as three main events took place co-located in space and time: the 1st International Conference on Quantification in Visual Computing (SFB-TRR 161), the 40th German Conference on Pattern Recognition (GCPR), and the 23rd International Symposium on Vision, Modelling, and Visualization (VMV).
The 4th International BDVA (Big Data Visual and Immersive Analytics) 2018 Symposium is a well-established scientific meeting that covers the area of Visual Analytics and Immersive Analytics of Big Data. The international symposium will be the first time held out of Australia at the University of Konstanz on October 17 – 19, 2018. BDVA 2018 offers researchers with the opportunity to be part of an exciting programme with internationally renowned keynote speakers, special sessions, and Workshops.
Mit Hilfe von VR-Ferngläsern ist das zur Zeit auf der Konstanzer Insel Mainau in der Ausstellung „Vom Bodensee nach Afrika – mit ICARUS auf Langstrecke“ möglich! An verschiedenen Stationen kann man hier die Entwicklungen in der Tierbeobachtung nachvollziehen und sich interaktiv über aktuelle Forschungsergebnisse informieren.
This years conference on visualization EuroVis 2018 took place from 4th June till 8th June. Besides the excellent works presented at the conference, there were lots of possibilities to discuss topics with people from diverse areas and to meet new people from various domains worth exchanging experiences.
At the end of January, Miriam Butt, Melanie Herschel, and Christin Schätzle (members of projects D02 and D03 of the SFB/Transregio 161) organized a workshop on Data Provenance and Annotation in Computational Linguistics in Prague, co-located with the Treebanks and Lingustic Theory (TLT16) conference.
At SIGGRAPH Asia 2017, we presented a technical paper titled “Weighted Linde-Buzo-Gray Stippling”. With this paper, we proposed a novel approach for sampling in computer graphics. Similar to cell division in biology, we iteratively split Voronoi cells until a target density distribution, for example based on an input image, is reached.
We presented an approach for uncertainty visualization of proteins at the 11th IEEE Pacific Visualization Symposium in Kōbe, Japan. In some application areas such as medical visualization or weather forecasting, uncertainty is nowadays often illustrated to enable a more informed visual analysis. However, molecular visualization rarely incorporates uncertainty, although it is present in the data.
Last year the EMMCVPR took place in Venice. During the conference we had the opportunity to presented our recent works on variational optical flow estimation in the context of large displacements and illumination changes. Meantime our results have been published!
