1 Video Registration: Key Challenges Richard Szeliski Microsoft Research

2 Key Challenges 1. Mosaics and panoramas 2. Object-based based segmentation (MPEG-4) 3. Engineering Support Data 4. 3-D D registration 5. Wide base-line stereo 6. Correlation 7. Video registration vs. visual tracking 8. Role of image features 9. Next most important problems 10.Most successful solutions and approaches July 13, 2001 Richard Szeliski 2

3 Mosaics and Panoramas Accomplishments: Fast direct methods Feature-based approaches for large motion True 3D alignment (spherical( mosaics) Focal length (f)( ) estimation (self( self-calibration) Moving objects (deghosting( deghosting) Exposure compensation July 13, 2001 Richard Szeliski 3

4 Mosaics and Panoramas July 13, 2001 Richard Szeliski 4

5 Mosaics and Panoramas Removing moving objects (deghosting( deghosting) July 13, 2001 Richard Szeliski 5

6 Mosaics and Panoramas Removing moving objects (deghosting( deghosting) July 13, 2001 Richard Szeliski 6

7 Mosaics and Panoramas Exposure compensation July 13, 2001 Richard Szeliski 7

8 Mosaics and Panoramas Exposure compensation and deghosting July 13, 2001 Richard Szeliski 8

9 Mosaics and Panoramas Challenges: dealing with parallax dealing with more complex motions large motions July 13, 2001 Richard Szeliski 9

10 Wide-baseline stereo Is wide base-line stereo solved now? Input image Sum Abs Diff Mean field Graph cuts July 13, 2001 Richard Szeliski 10

11 Wide-baseline stereo What about really wide baselines? July 13, 2001 Richard Szeliski 11

12 Wide-baseline stereo What about untextured regions? July 13, 2001 Richard Szeliski 12

13 Wide-baseline stereo What about untextured regions? July 13, 2001 Richard Szeliski 13

14 Wide-baseline stereo What about untextured regions? July 13, 2001 Richard Szeliski 14

15 Wide-baseline stereo What about untextured regions? July 13, 2001 Richard Szeliski 15

16 Wide-baseline stereo What is it being used for? view interpolation view extrapolation object removal / insertion video compression Desired solution depends on application July 13, 2001 Richard Szeliski 16

17 Role of image features Needed to establish original epipolar geometry [but see Hannah s direct methods] Once epipolar geometry is known, can use linear features or direct methods Useful for long-range motion: efficiency and robustness Features may vary in appearance [nice recent work by Schmid and Lowe] July 13, 2001 Richard Szeliski 17

18 Role of image features Not statistically optimal: 1. Weighting by feature certainty (doable) 2. Not using all of the pixels Patch-based alignment [Shum & Szeliski] Spline-based registration [Szeliski & Coughlan] July 13, 2001 Richard Szeliski 18

19 Role of image features Can your feature tracker track this? Sometime direct methods track the only data in the sequence July 13, 2001 Richard Szeliski 19

20 Next most important problems 1. Sub-pixel accurate registration 2. Transparency, reflections and specularities 3. Non-rigid motion July 13, 2001 Richard Szeliski 20

21 Sub-pixel accurate registration Problems at and near occlusions Incorrect color extraction, no partial occupancy in (mixed( mixed) ) border pixels July 13, 2001 Richard Szeliski 21

22 Layered Stereo Layers with alpha (opacity) July 13, 2001 Richard Szeliski 22

23 Results: Michael and Lee = + July 13, 2001 Richard Szeliski 23

24 Results: Anne and books = + July 13, 2001 Richard Szeliski 24

25 Non-rigid motion Multiple moving objects (segmentation) Articulated and soft motion Video textures (quasi-random or quasi- periodic) July 13, 2001 Richard Szeliski 25

26 VideoTextures video clip video texture

27 Video Textures How do we find good transitions?

28 Complete animation

29 Summary Video clips Video Textures discover Markov structure preserve dynamics disguise visual discontinuities separate regions user input create video-based animations Example of Video-Based Rendering

30 Next most important problems 1. Sub-pixel accurate registration 2. Transparency, reflections and specularities 3. Non-rigid motion July 13, 2001 Richard Szeliski 30
