Method Description:
The frontal-parallel assumption is made by many
matching algorithms, but this assumption fails
for slanted surfaces. This paper proposes a
matching algorithm intended to improve the
matching results for slanted surfaces. First, a
mathematical model is constructed to prove that
slanted surfaces in the environment have
corresponding slanted disparity surfaces in the
disparity space image (DSI), and the model is
to help find the proper plane parameters of
slanted support windows. Then, improved cost
aggregation and post-processing methods are
proposed.
Parameters:
D = 10, S = 4, window size = 51.

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.
