1. Capturing And Viewing Big, Wide, And Deep Imagery Michael F. Cohen Matt Uyttendaele Johannes Kopf MSR – Interactive Visual Media Universitaet Konstanz

2. BIG 3,600,000,000 Pixels Created from about 800 8 MegaPixel Images

3. BIG

4. Wide 150 degrees “Normal” perspective projections cause distortions.

5. Deep High Dynamic Range 100X variation in Radiance

6. Big, Wide, And Deep No longer a single “image” –So what is it? Requires a VIEWER to “explore” Issues –Capture –Viewing

18. Viewing Gigapixel Images (Wide) Want to pan and zoom Question: what “projection” = mapping from directions in the world to points on the image Most cameras use Perspective = flat film plane Panoramic cameras use Cylindrical Spherical or Fisheye are yet other mappings

19. Viewing Gigapixel Images (Wide) Perspective is good for narrow angle –Straight lines stay straight –Most like our perception –But distorts at wide angle Cylindrical, Spherical are good for wide angles –Allows you to see whole field of view –But makes straight lines curved and feels flat when panning Want best of both!
