Method Description:
We generate a matching cost volume leveraging both
data with ground truth and conventional wisdom. We
accomplish this by coalescing diverse evidence from
a bidirectional matching process via random forest
classifiers. We show that the resulting
matching volume estimation method achieves similar
accuracy to purely data-driven alternatives on
benchmarks and that it generalizes to unseen data
much better. For more details, please check our
paper.
Parameters:
\pi1=1.1 \pi2=27.0 \sgm_q1=3.0 \sgm_q2=2.0
\alpha=2.0 \tau=0.08 (There is a detailed setup of
the parameters in our paper)

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.
