Running time:3.2 s
Environment:4 cores @ 2.5 Ghz (C/C++)

Method Description:
Sparse to dense flow method which detects novel
Dense Gradient based Features (DeGraF) and uses
the
Robust Local Optical Flow (RLOF) to track the
points
and the EpicFlow edge aware interpolator to
recover
dense flow.
Parameters:
DeGraf window size: 3x3
Degraf window step size: 10px
For RLOF, using illumination model and motion
prior.
MSolverType: ST_STANDART
Interpolator: k = 128.

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.
