Running time:6 s
Environment:4 cores @ 2.5 Ghz (C/C++)

Method Description:
To effectively handle slanted objects in the scene,
we improve PatchMatch Stereo (PMS) algorithm.
We
introduce census measure with Semi-Global
Matching –
which produces great result on real-world scene
from
the automobile – into the PMS algorithm in the
manner of a multi-scale fusion.
Parameters:
alpha = 0.3
P1=400
P2=1600

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.
