Forschungsseminar SS 2011 Introductory session ( ) Institute of Computer Graphics and Algorithms Vienna University of Technology Contact: Stefan Jeschke )

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 scientific articles Summarizing and explaining (orally and/or written) Comparing and discussing Practice to give a talk or to write a report Experience critical scientific discussion

2 Tasks (Pre)requirements „Grundlagen Methodischen Arbeitens“ Basic knowledge in CG (“CG1” lecture) Attend 3 lectures: „Wie halte ich einen Vortrag“ (Prof. Purgathofer), Monday, at 14:00, in HS7 „Forschung und wie sie funktioniert“ (Prof. Gröller), Friday, at in EI2 „Wie schreibt man eine wissenschaftliche Arbeit “ (Prof. Breiteneder), Friday, at 14:15 in EI2 Stefan Jeschke

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

4 Procedure There will be regular meetings (about 6) with the advisor Small student groups (no more than 2-3) You explain your progress to other participants Idea: teach you scientific communication skills Language: (typically) German or in English Two options for presenting your results: Final talk (20 min + 5 min discussion) in English The best talks will be invited our Konversatorium OR written report in English (8-10 pages) Stefan Jeschke

5 Topics Ralf Habel: “Computational Photography” HDR, Lightfields, Motion Blur, Coded Aperture Paul Guerrero: “2D Shape descriptors – finding similarities in 2D shapes“ Compare Heat kernel signature and Fuzzy geodesics MATLAB implementation in an existing framework (40-50 code lines) Stefan Jeschke

6 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 Reinhold Preiner: “Real-time Rendering of Point Clouds” Massive point data rendering Splatting, texturing, shading,.. “Accurate Real-time Reflections” Stefan Jeschke

7 Topics Claus Scheiblauer: “Out-of-Core Processing of Point Clouds” External sorting, k-nearest neighbor search, streaming algorithms for rendering 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

8 Topics Oliver Mattausch: “Content-aware Image Resizing” How to preserve image content if the image is resized? Try out code from the web Murat Arikan: “Visibility in Point Clouds” “Seamless Texturing of from Photographs” Stefan Jeschke

9 Topics Matthias Bernhard: “Remedies for the accomodation-vergence conflict in stereo rendering” Results from discrepancy between lens accomodation and vergence of eyes during stereo rendering Remedies: multi-layer displays, disparity compression Stefan Jeschke: “(Semi) automatic shadow removal in images” Finding shadow regions (fully automatic/user interaction) Removing the shadow Stefan Jeschke
