Presentation Transcript

  1. Drawing, Painting and Stylization; Interactive image editing Xiaoguang Han 2011-07-04

  2. Papers • Interactive Editing of Massive Imagery Made Simple: Turning Atlanta into Atlantis (TOG) • Geodesic Image and Video Editing (TOG) • Matting and Compositing of Transparent and Refractive Objects (TOG) • Nonlinear Revision Control for Images (demo) • ShadowDraw: Real-Time User Guidance for Freehand Drawing • A Programmable System for Artistic Volumetric Lighting • Coherent Noise for Non-Photorealistic Rendering

  3. Gigapixel images

  4. Goal • InteractiveEditing - Real time - Minimal memory • Interactive Editing - Seamless cloning/panorama stitching - Gradient-based image processing

  5. Panorama stitching

  6. Progressive Poisson Solver • A global progressive solver provides a near instant coarse approximation of the full solution • A local progressive solver provides a quick solution for the visible pixels

  7. Edinburgh panorama 16,950*2,956

  8. Framework • Initial solution • Progressive refinement • Local preview • Progressive full solution • Out-of-core solver

  9. Turning Atlanta into Atlantis

  10. Contribution • A coarse-to-fine progressive Poisson solver running at interactive frame rates • A method to locally refine solutions having time and space requirements • A full out-of-core solver that maintains strict control over system resources • A lightweight streaming framework that provides adaptive multi-resolution access to out-of-core imges

  11. [ICCV2007] A geodesic framework for fast interactive image and video matting

  12. Geodesic matting

  13. Geodesic matting

  14. Geodesic distance (binary region)

  15. Generalized geodesic distance

  16. Geodesic morphology

  17. Geodesic Symmetric Filtering operator

  18. Interactive segmentation of high resolution image

  19. More results

  20. Flattening

  21. Goal • Matting & Compositing - Cut and Paste • Transparent and Refractive objects - no 3D information

  22. Appearance model • Specular highlights • Refractive Deformation • Light Attenuation

  23. Attenuation-Refraction Matte(ARM)

  24. ARM extraction • M-extraction

  25. G-extraction

  26. Results

  27. Results

  28. Motivation • Nonlinear Revision Control for documents

  29. Current Linear Revision Control for images

  30. Nonlinear Revision Control

  31. Revision graph

  32. Motivation • Freehand Drawing - human intuition - rough & difficult • Context based image retrieval - computer intelligence - not people’s want & time-consuming

  33. Goal • Real-time user guidance - computer is a partner in drawing process

  34. Approach • Database Creation - 40 categories: t-shirt, bicycle, car, etc. - edge extraction - patch descriptors - min-hash

  35. Image Matching • Candidate matches • Image alignment • Image weighting

  36. Results

  37. User study

  38. Goal • Volumetric effect

  39. Thanks!
