Environment:4 cores @ 2.5 Ghz (C/C++)

Method Description:
Implements a principled coarse-to-fine local method that uses
oriented windows in order to deal with slanted surfaces and
discontinuities. Results are non-dense as mismatches are
detected and removed from the output. Notably, ambiguous
matches are detected by a filter based on the notion of
\emph{distinctiveness}, while most occluded and dis-occluded
pixels are detected using the \emph{min-filter}.
Parameters:
window_size=9x9
orientations=5
scales=4
rmd=1
mdd=-1
ss=0
p=4
combine=0
grain=50
post=1

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.
