Running time:2.6 min
Environment:1 core @ 3.0 Ghz (Matlab)

Method Description:
Modified HS implementation from CVPR 2010 paper.
Parameters:
Same as in the CVPR 2010 paper except the use of an
asymmetric pyramid to deal with the large aspect
ratio of the KITTI data.

Detailed Results

This page provides detailed results for the method(s) selected. For each of the first 20 test images, the number of erroneous pixels at all thresholds is depicted in the table. Underneath, the left input image, the disparity / end-point error map and the estimated (and interpolated) disparity / optical flow map are shown. The error map scales linearly between 0 (black) and >=5 (white) pixels error. Red denotes all occluded pixels, falling outside the image boundaries. The false color map is scaled to the largest ground truth disparity / flow value.
