Project Status : Apr 11

Basic GPU implementation has been completed on a Dell P.O.S workstation, 500 MB RAM, 3GigaWatts., with a custom-modified nVidia 7900 GTX (PCI-X, 512MB RAM). Using the DigiClops camera capture drivers for the BumbleBee stereo camera.

Results

• Upper Left: DepthMap( red = closer )
• Upper Middle : Slice of 3D volum ( height x max disparity ). Note the darkened image plane
• Upper Right - slice mins
• Middle : Left, Right Camera Pairs ( relaxed )
• Lower (small) right, left ( cross-eyed pairs )

Results at present are approximately 12-13 FPS for 320x240, for a single 3-direction pass on the left-image. ( Ask me about how this compares to CPU! )

Major Issues

• sequential min-operations
• texture layout, contiguous access

Applications

Depth-Cued Background Subtraction

Depth-of-Field Effect
