Goal
Develop an algorithm to reconstruct a 3D world scene from two static 2D images

Approach
• Acquire digital images
• Match up corresponding points in both images
• Estimate a depth mask
• Generate an image from a new view.

Movies
Low resolution movies are currently online at:http://www.cae.wisc.edu/~shultz/movie
High resolution copies are on CD and available by request

Conclusion
• Movies are convincing
• Masks are not perfect, but adequate to fool the eye
• Currently manually intensive, point matching process could be automated.
• Could be modified to incorporate multiple views.
