  1. Partial Intrinsinc reflection symmetry of 3d shapes EladWalach

  2. Reflection symmetry

  3. Partial

  4. intrinsic

  5. Concepts • PIRS • partial intrinsic reflectionalsymmetry • IRSA • Intrinsinc reflection symmetry axes

  6. overview

  7. In The beginning: prst

  8. PRST: Voting

  9. Lets get 3d • Lines are not that simple! • No shape boundary.. We only have the manifold • Cant easily calculate the reflection

  10. IRSA SCORE

  11. Lets vote

  12. Lets vote (II)

  13. Four Filters of the Apocalypse

  14. Similarity filter • Is only p,qdepndant • How similar is the point environment

  15. Distance filter

  16. Locality

  17. Axial sym • The final filter makes sure the symmetry is axial instead of point symmetry • Pool of all points who passed the filters so-far

  18. Four Filters of the Apocalypse

  19. Applications : Segmentation

  20. Results

  21. More Results

  22. Application: Part Repair

  23. Conclusion • Partial intrinsinc reflection symmetry of 3d shapes • Uses: • Segmentation • Part repair
