Method Description:
This is a local stereo method.The match­ing frame­work consists of a combination of robust cost mea­sures, extracted via li­near­ly expanded cross skeleton support regions and set within a coarse-to-fine strategy.
Parameters:
census transformation: [m,n]= [11,9]
λc=45,
λADc=5,
λADg=18,
Lmax=31,
τmax=24,

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.
