Method Description:
Descriptor matching on regions provides a sparse
set of hypotheses for correspondences. These are
integrated into a variational approach and guide
the local optimization to large displacement
solutions. The variational optimization selects
among the hypotheses and provides dense and
subpixel accurate estimates, making use of
geometric constraints and all available image
information.
Parameters:
default parameters

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.
