  1. Weekly Lab Report 2010.07.14 ~ 2010.07.21

  2. Progress (Hanyu Hong) • Finishing OE Revision • Our contribution is the accuracy of motion path from single image. • more accurate than Other methods. • Fergus, Shan,not accuracy. • Object motion path in our work.

  3. Plan (hanyu hong) • Two view deblurring • Codes Programming • deblurring experiments

  4. Progress (Man Hee Lee) • Mobile avatar • Convert NURBS to mobile • Optimize the curve rendering • It’s possible to get the arbitrary 2D position that correspond to the feature of 3D model • Apply NURBS to active snake • In debugging

  5. Plan (Man Hee Lee) • Mobile avatar • Active snake • Finish debugging • Apply NURBS feature to 3d warping • Improve 2D UI

  6. Progress (Nicolas) • OOPGPU • Worked on the source code • Source repository structure: For personal work For sharing the current development version For general public (version downloads) For developers

  7. Progress (Nicolas) • OOPGPU (cont’d) • Source code repository: • Found out that the password transmission protocol in use wasn’t secured, now encrypted (MD5) • Implemented custom rights for users • Read only, r/w • Anonymous authentication for general subpart of the repo, password for developer part • User groups (currently: developper and reviewers)

  8. Progress (Nicolas) • OOPGPU (cont’d) • DSL tools: learned how to generate basic code for the library (video)

  9. Plan (Nicolas) • Improve the code generation language • Processing stages • GPU code generation (CUDA, OCL & GLSL) • Implement 3 technologies (CUDA, OCL & GLSL) • Prepare the tutorial

  10. Progress( Tae Jang Park) • HDR • Our camera do not support SDK • Try to experiment • Take a HDR in environment with various lighting. • Shutter speed : 1, 2, 4, 8, 16, 24, 32ms

  11. Progress( Tae Jang Park) • Lux : 4330

  12. Progress( Tae Jang Park) • Lux : 9900

  13. Progress( Tae Jang Park) • Lux : 34300

  14. Progress( Tae Jang Park) • HDR • Problem • Pattern recognition is very difficult. • Shutter speed above 16 is not detected.

  15. Plan( Tae Jang Park) • HDR • Search for control each camera of bumblebee. • Implementation Debevec algorithm.

  16. SURF Study GLSL and Android NDK(Native Development Kit) Study SURF implement using GPU Deblurring Check the processing time Modify the paper Progress (Jin Woo Yoo) 17

  17. Plan (Jin Woo Yoo) SURF Study OpenGL ES 2.0 and Android NDK Study GPU SURF Deblurring Modify the paper 18

  18. Structured lighting Three phase-shifting Test image (image size: 480*640) Progress (Jae Hyun WON)

  19. Structured lighting Three-step phase-shifting Phase image Problem: phase discontinuity Progress (Jae Hyun WON)

  20. Phase unwrapping Make quality map Progress (Jae Hyun WON) Remove background • Gradient of phase map

  21. Phase unwrapping Progress (Jae Hyun WON)

  22. Three-step phase shifting Make depth image Test camera image Plan (Jae Hyun Won)

  23. Progress (Won Beom Lee) • 3D Face Modeling • Implementation • generated a texture map. • calculated texture coordinates. • cylinder mapping • the result is not accurate • one to one mapping between feature points and 3D model vertex need to be improved. • haven’t applied to warping on profile feature points.

  24. Progress (Won Beom Lee)

  25. Plan (Won Beom Lee) • 3D Face Modeling • Implementation • be going to make a more accurate result. • color alignment between two source images.

  26. Progress (Ho Yeol Choi) • Study • GLSL Shader language • Android • Paper • Depth Discontinuities by Pixel-to-Pixel Stereo, International Journal of Computer Vision, 35(3): 269-293, December 1999, Stan Birchfield and Carlo Tomasi • Implementation • GLSL example

  27. Plan (Ho Yeol Choi) Implement simple stereo program 28
