Method Description:
Implements a local method, i.e. winner-takes-all
solution, but prior to disparity selection smoothes
the cost volume using a very efficient edge
preserving filter (approximation to bilateral
filter).
Parameters:
r = 9;
eps = 0.0001;
thresColor = 7/255;
thresGrad = 2/255;
gamma = 0.11;
threshBorder = 3/255;
gamma_c = 0.1;
gamma_d = 9;
r_median = 19;
numDisp = 128;

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.
