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.

Detailed Results

This page provides detailed results for the method(s) selected. For the first 20 test images, the percentage of erroneous pixels is depicted in the table. We use the error metric described in Object Scene Flow for Autonomous Vehicles (CVPR 2015), which considers a pixel to be correctly estimated if the disparity or flow end-point error is <3px or <5% (for scene flow this criterion needs to be fulfilled for both disparity maps and the flow map). Underneath, the left input image, the estimated results and the error maps are shown (for disp_0/disp_1/flow/scene_flow, respectively). The error map uses the log-color scale described in Object Scene Flow for Autonomous Vehicles (CVPR 2015), depicting correct estimates (<3px or <5% error) in blue and wrong estimates in red color tones. Dark regions in the error images denote the occluded pixels which fall outside the image boundaries. The false color maps of the results are scaled to the largest ground truth disparity values / flow magnitudes.
