1. EVENTS: INRIA Work Review Nov 18 th, 2002. Madrid.

2. Two Input Frames

3. Problems: Objects on Different Planes

4. Problem: Current Minimum Resolution is Triangle

5. Separate Objects on Different Planes

6. Approach Separate images into Background and Foreground objects Extension to Dynamic Scenes?

7. Scenario: Dynamic Scenes Fixed or static background Moving objects (i.e. players)

8. Scenario: Camera Motion What can be done with moving camera (rotations, zoom and focus changes)

9. Segmenting Player Initial foreground H H

10. Segmenting Player Initial foreground - -

11. Segmenting Player Initial Foreground Corresponding Background

12. Segmenting Player 1...k...N statistics

13. Background

14. Advantages Segmentation of foreground objects Arbitrary foreground resolution can be handled Background model generated

15. Open Problems Different planes on background are still not segmented Real time?

16. Extension to Multiple Views Background interpolation need to be done only once Only foreground objects need to be interpolated

17. Synchronization of Stereo-Data Player Tracker – Modified Mean Shift Track positions are used to recovered 3D trajectories of players Novel curve registration framework Automatic

18. Conclusions Automatic Segmentation of foreground Objects Background model generation Synchronization of Stereo Data
