Brief Bio
Stephan Diehl is a full professor at University Trier, Germany. His main research areas are software engineering and information visualization, and in particular the intersection of both areas, nameley software visualization. A considerable part of his visualization research can be briefly characterized as applying (visual) data mining techniques to analyze software evolution and developing new ways to visualize the change of structured information over time. Stephan Diehl is author of the book "Software Visualization -- Visualizing the Structure, Behavior and Evolution of Software" (Springer). He is a member of ACM, IEEE, and GI, the steering committees of the IEEE working conference series on Mining Software Repositories MSR and on Software Visualization VISSOFT. Since 2007 he is a member of the scientific directorate of Schloss Dagstuhl -- Leibniz-Center for Informatics.
Abstract
Starting with a selective retrospective of the history of software visualization, I will identify various trends and paradigms of previous and current research. In particular, I will discuss examples of applying visualization techniques to analyze the past and present state of software as well as to predict its future development. I will argue that prediction is an important task, but that software visualization research has only scratched the surface of it. As a consequence, speculative visualization will be one of the major future challenges identified in this talk.

Abstract
Our society is creating, storing and using an ever increasing volumes of digital multimedia content. We have access to hundreds of billions of images and videos on the Internet, in the archives of professional content creators and owners, and in the personal libraries of home users. In this context, content-based identification of images' and videos and visual search capabilities are essential enablers for a range of applications that require fast, robust and efficient algorithms. The interoperability of the technologies and systems is also an important consideration.
During the lecture Miroslaw Bober will review the latest advances in content fingerprinting and visual search and how they impact related standardisation efforts within the MPEG group. In particular will present the MPEG Visual Signatures, which include the Image Signature and Video Signature content description tools. The Visual Signatures are designed specifically to enable fast and robust identification of near duplicate or derived (modified) visual content in large-scale databases. We will also look at the latest addition to the MPEG family of standards: Compact Descriptors for Visual Search (CDVS). Achieving a state-of-the-art identification and recognition performance, the applications are numerous and include rights management and monetization, distribution management, usage monitoring, and professional or personal database management.

Abstract
One of the grand challenges in our networked world are the large, weakly structured and unstructured data sets. This is most evident in Biomedicine (Medical Informatics + Bioinformatics): The trend towards personalized medicine results in increasingly large amounts of (-omics) data. In the life sciences domain, most data models are characterized by complexity, which makes manual analysis very time-consuming and often practically impossible. To deal with such data, solutions from the machine learning community are indispensable and it is marvelous what sophisticated algorithms can do within high-dimensional spaces. We want to enable a domain expert end-user to interactively deal with these algorithms and data, so to enable novel discoveries and previously unknown insights. Our quest is to make such approaches interactive, hence to enable a computationally non-expert to gain insight into the data, yet to find a starting point: “What is interesting?”. When mapping the results back from arbitrarily high-dimensional spaces R^n into R^2 there is always the danger of modeling artifacts, which may be interpreted wrongly. A synergistic combination of methodologies and approaches of two areas offer ideal conditions towards working on solutions for such problems: Human-Computer Interaction (HCI) and Knowledge Discovery/Data Mining (KDD), with the goal of supporting human intelligence with machine intelligence. Both fields have many unexplored, complementing intersections and the aim is to combine the strengths of automatic, computer-based methods, both in time and space, with the strengths of human perception and cognition, e.g. in discovering patterns, trends, similarities, anomalies etc. in data.

Abstract
With augmented reality becoming increasingly mobile, the need for ubiquitously available and flexibly configurable tracking services is becoming more and more urgent. At TU Munich we envision AR-ready environments that offer stationary tracking resources - to be fused on mobile devices with their own, built-in tracking facilities, depending on availability and application requirements. The talk will describe the underlying principles and capabilities of the Ubitrack system that is being developed in Munich.
