Method Description:
Feature warping is a core technique in optical
flow estimation; however, the ambiguity caused by
occluded areas during warping is a major problem
that remains unsolved. In this paper, we propose
an asymmetric occlusion-aware feature matching
module, which can learn a rough occlusion mask
that filters useless (occluded) areas immediately
after feature warping without any explicit
supervision. The proposed module can be easily
integrated into end-to-end network architectures
and enjoys performance gains while introducing
negligible computational cost. The learned
occlusion mask can be further fed into a
subsequent network cascade with dual feature
pyramids with which we achieve state-of-the-art
performance. At the time of submission, our
method, called MaskFlownet, surpasses all
published optical flow methods on the MPI Sintel,
KITTI 2012 and 2015 benchmarks.

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.
