1. Seminar aus Computergraphik WS 2011Introductory Session (06.10.2011) Contact: Stefan Jeschke (jeschke@cg.tuwien.ac.at) Institute of Computer Graphics and Algorithms Vienna University of Technology

2. Mission statement • Learn basic scientific work flow (in CG) and improve scientific communication skills • Practice to review literature and get familiar with a particular scientific topic: reading and understanding (difficult) scientific articles • Summarizing and explaining (orally / written) • Comparing and discussing: experience critical scientific discussion • Practice to give a talk or to write a report Stefan Jeschke

3. Tasks • (Pre)requirements • Basic knowledge in CG (“CG1” lecture) • Attend 3 lectures: • „Forschung und wie sie funktioniert“ (Prof. Gröller), 9.11. at 5 PM in this room • „Wie halte ich einen Vortrag“ (Prof. Purgathofer),16.11. at 5 PM in this room • „Wie schreibt man eine wissenschaftliche Arbeit “ (Prof. Wimmer), 23.11. at 10:30 AM in this room Stefan Jeschke

4. Procedure • Analyze some recent papers (select with advisor) • Literature study relevant for paper understanding • Paper results evaluation: compare with existing results / code from the web / implement it (if reasonable amount of work) • Does the algorithm work as described? • How do parameters influence the result? • When does the algorithm fail? (models/images/etc) • How fast is the algorithm on current hardware? Stefan Jeschke

5. Procedure • There will be regular meetings (about 6) with the advisor • Small student groups (2-4) • You explain your progress to other participants • Idea: teach you scientific communication skills • Language: (typically) German or in English Stefan Jeschke

6. Procedure • Options for presenting your results: • Final talk: • 20 min + 5 min discussion • English language • Date: 26.01.2012 at 10 AM in this room • Best talks are invited to our Konversatorium • Written report • 8-12 pages • English language • Deadline: 27.01.2012 Stefan Jeschke

7. Topics • Martin Knecht: • “Real-time tracking and reconstruction” • Kinect fusion: try different tools/techniques Stefan Jeschke

8. Topics • Thomas Auzinger: • “Video Stabilization” • State-of-the-art methods in video stabilization and related improvements of video sources • Review of available source code and programs Stefan Jeschke

9. Topics • Paul Guerrero: • “Contour completion“ • Given image and edge map, complete ‘meaningful’ edges • Implement/try existing algorithm(s) Stefan Jeschke

10. Topics • Martin Ilcik: “Critical overview of interior design software” • Try out solutions for interior modeling and planning • Compare capabilities, look for advanced features, collect background info and judge about the data structures and algorithms Stefan Jeschke

11. Topics • Reinhold Preiner: • “Surface Reconstruction from Point Clouds” • Noise removal, etc. • Fast kNN search • “Computing perspective projections of a sphere” • Algorithms, implementations, applications • Numerical stability, accuracy, speed Stefan Jeschke

13. Topics • Claus Scheiblauer: • “Out-of-Core Processing of Point Clouds” • External sorting, kNN, streaming algorithms etc. Stefan Jeschke

14. Topics • Matthias Bernhard: • “Accomodation-vergence conflict in stereo rendering” • Discrepancy between eye accomodation and vergence • Remedies: multi-layer displays, disparity compression Stefan Jeschke

15. Topics • Ralf Habel: • “Computational Photography” • HDR, Lightfields, Motion Blur, Coded Aperture Stefan Jeschke

16. Topics • Stefan Jeschke: • “Dimensionality Reduction in CG” • Linear: PCA • Nonlinear: Isomaps, Local Linear Embedding Stefan Jeschke

17. Topics • Stefan Jeschke: • “Shape segmentation in 2D and 3D” • Understand 1-3 techniques • Evaluate existing tools Stefan Jeschke
