Title: Model-based analysis of dynamic scenes from range-color video
Lecturer: Prof. Reinhard Koch Christian, Albrechts University Kiel, Germany.
Date: Wednesday 4^th of June 2014
Time: 15.15-16.00
Place: Room M108, Campus Sundsvall

Abstract
Tracking of deformable objects from video is a challenge due to the large dimensionality of the problem, when the deformation modes are unknown. Examples are tracking of cloth, elastic materials, or thin surfaces under external forces in realtime for interactive purposes. In this talk, I will discuss our approach of handling such scenes by observing the deformation in 3D videos stream consisting of depth and color, like for example the Kinect sensor device.  The key is a very fast model-based analysis-by-synthesis approach that models the observed object and its deformations in realtime, and synthesises the expected observation into a virtual camera. Based on the observed difference between synthesized and real video, a stochastic global optimisation adapts model geometry, position, and deformation modes in a feedback loop, and allows for interactive manipulation of the scene. 

Reinhard Koch holds a PhD (Dr.-Ing., 1996) in Electrical Engineering from the University of Hannover, Germany. From 1996 - 99 he lead the 3D modeling team at the KU Leuven, Belgium, in the vision group of prof. Luc van Gool. Since 1999 he is professor and head of the Multimedia Information Processing group at the Department of Computer Science of the Christian-Albrechts-University of Kiel. The research interests are 3D modeling from video, images, and depth sensors, fast camera calibration and tracking algorithms, depth-based 3D-TV and the confluence of Computer Graphics and Computer Vision in the field of Mixed and Augmented Reality.

Associate Professor Klas Nordberg

Title: "Motion segmentation in video sequences".
Lecturer: Associate Professor Klas Nordberg, Linköping University (Sweden).
Date:June 10^th 2013.
Time: 16.00
Room:L408, Campus Sundsvall.

Abstract
Besides other visual cues, such as color or texture, segmentation of objects in a video sequence can be made based on motion.  A common assumption used in this case is that any object in the scene move in 3D space in accordance to a rigid transformation, and that distinct objects move in accordance with distinct rigid transformations.  Assuming that a set of image points have been tracked along the images of a video sequence, each such point follows that projected motion trajectory of a specific objects, and the segmentation task implies grouping points that belong to the same object, i.e., are moving in accordance with the same rigid transformation.  The talk presents some of the standard methods for dealing with this segmentation problem, together with a specific approach developed at Linköping University.

Biography Klas Nordberg
Klas Nordberg has obtained the Master of Science in Computer Science in 1988, PhD in Image Processing in 1995 and the Docent degree in Computer Vision in 2012. He has held a position as Research assistant at Linköping University 1995-1998, and he is employed as Senior Lecturer at the same university since 1998.

Professor Hans-Jürgen Zepernic

Title: "Quality of Mobile Multimedia Experience".

Abstract
The rapid evolution of wireless networks is driven by the growth of wireless packet data applications such as interactive mobile multimedia applications, wireless streaming services, and video-on-demand. The largely heterogeneous network structures, severe channel impairments, and complex traffic patterns make the wireless networks much more unpredictable compared to their wired counterparts. One of the major challenges with the roll-out of these services is therefore the design of wireless networks that fulfill the stringent quality of service requirements of mobile multimedia applications. In this presentation, perceptual image and video quality metrics for real-time quality assessment of mobile multimedia experience are discussed. This includes a classification of quality assessment methods, comparison of psychophysical versus engineering approaches, perceptual image and video quality assessment, and some example applications.
