Running time:0.5 s
Environment:GPU @ 2.5 Ghz (Python)

Method Description:
First, stereo global matching for one-to-one
matching is applied to estimation initial
disparity and a contextual reasoning network is
used to refine the initial disparity. Finally, the
refined disparity is passed to GRU iterations for
final refinement.
Parameters:
batch size = 6
total steps = 50000

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.
