  • CS Graduate Seminar | 3D Reconstruction from Densely Sampled Videos

    Oct 03 2016 12:00 PM - Oct 03 2016 01:00 PM By Professor Hendrik P. A. Lensch (Tübingen University, Germany)

    Videos consisting of thousands of high resolution frames are challenging for existing structure from motion (SfM) and simultaneous-localization and mapping (SLAM) techniques. We present new approaches for simultaneously computing extrinsic camera poses and 3D scene structure that is capable of handling such large volumes of image data. A further extension is the treatment of deformable camera rigs. The key insight behind this work is to effectively exploit coherence in densely sampled video input both for camera localization as well as for dense 3D surface reconstruction.

    Biography: Hendrik P. A. Lensch holds the chair for computer graphics at Tübingen University and is the head of the computer science department. He received his diploma in computers science from the University of Erlangen in 1999. He worked as a research associate at the computer graphics group at the Max-Planck-Institut für Informatik in Saarbrücken, Germany, and received his PhD from Saarland University in 2003. Hendrik Lensch spent two years (2004-2006) as a visiting assistant professor at Stanford University, USA, followed by a stay at the MPI Informatik as the head of an independent research group. From 2009 to 2011 he has been a full professor at the Institute for Media Informatics at Ulm University, Germany. In his career, he received the Eurographics Young Researcher Award 2005, was awarded an Emmy-Noether-Fellowship by the German Research Foundation (DFG) in 2007 and received an NVIDIA Professor Partnership Award in 2010. His research interests include 3D appearance acquisition, computational photography, global illumination and image-based rendering, as well as massively parallel programming.

  • CS Graduate Seminar | On solving large-scale MRFs on GPUs and on evaluating image-based modeling and rendering systems

    Sep 26 2016 12:00 PM - Sep 26 2016 01:00 PM Image-based modeling and rendering systems have made tremendous progress in recent years. Motivated by our own modeling and rendering pipeline, I will present two separate contributions:First, I will discuss the challenges in evaluating the end-to-end quality of image-based modeling and rendering system. I will then introduce our proposed methodology, discuss several quality metrics and show its relationship to existing benchmarks. One of the key advantages of this approach is that it does not require ground truth geometry. Finally, I will conclude the first part of my talk by introducing our new image-based modeling and rendering benchmark. In the second part of the talk, I will focus on solving large-scale MRFs, one of the key bottlenecks in the texturing stage of our reconstruction pipeline. I will first discuss strategies to parallelize the solution of large scale MRFs with a focus on massively-parallel approaches suitable for modern GPUs. I will then introduce our solver that supports arbitrary MRF topologies efficiently and can handle arbitrary, dense or sparse label sets as well as label cost functions. Together with two additional heuristics for further acceleration, our solver performs favorably even compared to modern specialized solvers in terms of speed and solution quality, especially when solving very large MRFs. This is joint work with Michael Waechter, Mate Beljan, Simon Fuhrmann, Nils Moehrle, Johannes Kopf, Daniel Thuerck, Sven Widmer, Max von Buelow, Patrick Seemann and Marc E. Pfetsch.
  • KAUST – Conference on Computational Imaging and Visualization (CIV)

    Feb 29 2016 09:00 AM - Mar 02 2016 05:00 PM The Visual Computing Center at King Abdullah University of Science and Technology is hosting an international conference on Computational Imaging and Visualization.
    This conference will explore the interface of Computational Imaging (i.e. the joint design of new imaging hardware and algorithms to capture and encode information), and Visualization (i.e. the generation of visual representations for scientific and other datasets). The focus of this conference will be on new methods and applications for computational imaging and scientific visualization in science, engineering, and medicine.
