The Immersion '94 project led by Michael Naimark at Interval Research
Corporation used stereo imagery and image-based modeling and rendering
techniques to capture and render a virtual hike down the trails of
Banff National Forest. The project team consisted of Michael Naimark,
John Woodfill, Paul Debevec,
and Leo Villareal. See also the Dimensionalization Studies page maintained by Michael Naimark.

| The top two photos are a stereo pair (reversed for cross-eyed stereo
viewing) taken in 1993 by Michael Naimark in Canada's Banff National
forest. In the center is a depth map computed using a stereo
correspondence algorithm designed by John Woodfill and Ramin Zabih;
intensity indicates depth, with brighter pixeles being closer. Pixels
the algorithm did not reliably match are indicated in blue. Below are
two virtual views generated by casting each pixel out into space based
on its depth, and reprojecting it into a virtual camera. On the left
is the result of virtually moving one meter forward, on the right is
the result of virtually moving one meter backward. Note the dark
de-occluded areas produced by these virtual camera moves; these areas
were not seen in the original stereo pair. In the animations below,
such regions were filled in from neighboring stereo pairs. Michael Naimark presented the Immersion '94 project at SIGGRAPH 95 at the panel session "Museums without Walls: New Media for New Museums". Click below for a QuickTime of the video animations from the project: |
