Method Description:
In this paper, we have proposed a new method,
Stratified Dense Matching. Our approach improves
the discriminability of matching features by
selecting a suitable matching window shape. The
windows are defined to adapt to high-correlation
structures in disparity space that represent all
matching hypotheses. The window definition in
disparity space allows the matching to adapt to
slanted and curved surfaces, scale differences,
and discontinuities. The stratified matching
approach is independent on the selection of the
matching algorithm, although it is desirable to
use a pre-matching algorithm that guarantees low
false negative error and a final matching algorithm
that guarantees low false positive error and
mismatch error.
Parameters:
searchrange = [0 256];
csalpha = 0;
csbeta = 0.05;

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.
