1. Bringing Photographs to Life With View Morphing Bringing Photographs to Life With View Morphing Steve Seitz University of Wisconsin—Madison

2. Images Are Static Photographs Lack –Movement — scene is frozen in time –Depth — image is two-dimensional Can we animate the scene via the image?

3. Objective: Scene Interaction Via Photos Scene Viewing –Move virtual camera, view real scene Scene Interaction –Move objects — cut and paste –Change objects — paint, sculpt –Animate the scene — make things walk, talk

4. Adding Movement Original Image Expression Change

5. Adding Depth Original Image Perspective Change

6. Talk Outline Adding Motion and Depth View Morphing Applications Visualization, photo correction, special effects Interacting With the Scene Scene editing via photographs

9. 1. Prewarp align views

10. 1. Prewarp align views 2. Morph move camera

11. 1. Prewarp align views 2. Morph move camera 3. Postwarp point camera

12. Features of View Morphing Provides –A mobile virtual camera –Better image morphs Requires no prior knowledge –No 3D shape information –No camera information –No training on other images

13. Applications: Visualization User-controlled Virtual Camera –Telepresence — visit a remote scene –Web commerce — product viewing over Internet –Viewing historical sites –Animating paintings

14. Applications: Photo Correction Image Postprocessing –Alter image perspective in the lab Image Databases –Normalize images for better indexing –Simplify face recognition tasks

15. Corrected Photographs Original Photographs

16. Applications: Better Image Transitions –Avoid bending and shearing distortions –Shapes do not need to be aligned Image Morph View Morph

17. The Next Step: Interacting With the Scene Scene Editing Via Photographs –Move objects — cut and paste –Change objects — paint, warp Scene Painted Photo Photo Propagation

21. Conclusions Photographs Come Alive –Motion, depth added by View Morphing User-Scene Interaction Via Photos –Still images interactive movies –What kinds of scene changes are possible? –Which modes of interaction are natural?
