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

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
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!
Viewing Gigapixel Images (Wide) Ours Cylindrical Perspective
Big, Wide, Deep Images • Thanks
