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.
Diese Woche startete die MS Wissenschaft ihre Tour in Berlin-Mitte. Mit an Bord des Ausstellungsschiffes ist ein Touch-Tisch der Universität Stuttgart und Universität Konstanz, an dem man erfahren kann, wie der nachhaltige Fortschritt durch Visual Computing unsere zukünftige Arbeitswelt beeinflusst.
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!
Ich bin Tim, 15 Jahre alt und wohne in Heidenheim, gehe zur Schule allerdings aufs Internat in Schwäbisch Gmünd. Jeder Schüler in Baden-Württemberg muss in der 10. Klasse ein Praktikum absolvieren, welches als BOGY-Praktikum bekannt ist. So auch ich. Insgesamt kann ich sagen, dass die BOGY-Woche für mich eine wunderschöne Zeit war und ich einen richtig guten Einblick in den Berufsalltag von Informatikern bekommen habe.
During my research stay at InnoVis, University of Calgary, Canada I worked with Lindsay MacDonald Vermeulen, Jo Vermeulen, Charles Perin, Wesley Willett, Thomas Ertl, and Sheelagh Carpendale on a project, which recently was accepted to the IEEE Transactions on Visualization and Computer Graphics.
On Wednesday September 20th, Jakob Karolus and me ran a Physical Computing and Biosensing Hackathon within the context of the AffecTech training week in Lancaster. In this day-long event, 15 AffecTech Ph.D. students with backgrounds ranging from Clinical Psychology to Human-Computer Interaction worked in multidisciplinary groups to create systems that support people coping with emotional and affective conditions.
Mein BOGY war eine rundum sehr gelungene Woche, in der ich viel Neues erfahren und gelernt habe, aber auch Spaß daran haben konnte, mich mit anderen Studenten, Doktoranden und Professoren zu unterhalten. Es war eine Bestärkung in meinem Berufswunsch ein Studium im MINT-Bereich zu machen, auch wenn ich noch nicht sicher bin, in welche Richtung es genau gehen wird.
During December 2017, I have visited Prof. Dietmar Saupe’s group at the University of Konstanz, Germany. In my first week I had the chance to give a talk about Image quality assessment based on visual perception as part of the Lecture Series “Visual Computing” of the SFB-TRR 161. During the month I was mainly working on the image quality assessment of differently distorted images.
At the software visualization conference VISSOFT, we presented a tool for tracing memory access patterns of arbitrary applications at runtime and then doing post-mortem visual analysis. The purpose of this visualization is to help developers finding hints for optimization of their code regarding memory usage. This is important for many applications in the area of high-performance computing, especially because the gap between processor and memory speeds continues to grow. Thus, memory accesses pose a bottleneck for performance-critical applications.
