Paper: Stereo Matching in the Presence of Sub-Pixel Calibration Errors

Conference: CVPR 2009

Codec: DivX (www.divx.com)

Supplemental to paper 796, we submit a short video that shows a typical
scene of a driver assistance scenario. The stereo sequence is slightly
decalibrated with an error of approximately 0.5 pixel. The following
sequence of disparity images shows the matching results using different
matching costs. It can be easily seen that the nearly horizontal structure
of the building in the end of the scene causes severe matching errors if
matching costs are used that do not compensate the calibration error. In
contrast, the suggested XSobelCensus and HBilSubBT cost perform pretty well.
