1 Seminar aus Computergraphik WS 2011 Introductory Session ( ) Institute of Computer Graphics and Algorithms Vienna University of Technology Contact: Stefan Jeschke )

2 Stefan Jeschke 1 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

3 2 Tasks (Pre)requirements Basic knowledge in CG (“CG1” lecture) Attend 3 lectures: „Forschung und wie sie funktioniert“ (Prof. Gröller), at 5 PM in this room „Wie halte ich einen Vortrag“ (Prof. Purgathofer), at 5 PM in this room „Wie schreibt man eine wissenschaftliche Arbeit “ (Prof. Wimmer), at 10:30 AM in this room Stefan Jeschke

4 3 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 4 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 5 Procedure Options for presenting your results: Final talk: 20 min + 5 min discussion English language Date: at 10 AM in this room Best talks are invited to our Konversatorium Written report 8-12 pages English language Deadline: Stefan Jeschke

7 6 Topics Martin Knecht: “Real-time tracking and reconstruction” Kinect fusion: try different tools/techniques Stefan Jeschke

8 7 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 8 Topics Paul Guerrero: “Contour completion“ Given image and edge map, complete ‘meaningful’ edges Implement/try existing algorithm(s) Stefan Jeschke

10 9 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 10 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

12 11 Topics Murat Arikan: “Visibility in Point Clouds” “Seamless Texturing from Photographs” Stefan Jeschke

13 12 Topics Claus Scheiblauer: “Out-of-Core Processing of Point Clouds” External sorting, kNN, streaming algorithms etc. Stefan Jeschke

14 13 Topics Matthias Bernhard: “Accomodation-vergence conflict in stereo rendering” Discrepancy between eye accomodation and vergence Remedies: multi-layer displays, disparity compression Stefan Jeschke

15 14 Topics Ralf Habel: “Computational Photography” HDR, Lightfields, Motion Blur, Coded Aperture Stefan Jeschke

16 15 Topics Stefan Jeschke: “Dimensionality Reduction in CG” Linear: PCA Nonlinear: Isomaps, Local Linear Embedding Stefan Jeschke

17 16 Topics Stefan Jeschke: “Shape segmentation in 2D and 3D” Understand 1-3 techniques Evaluate existing tools Stefan Jeschke
