Method Description:
To date, top-performing optical flow estimation
methods only take pairs of consecutive frames
into account. While elegant and appealing, the
idea of using more than two frames has not yet
produced state-of-the-art results. We present a
simple, yet effective fusion approach for multi-
frame optical flow that benefits from longer-term
temporal cues. Our method first warps the optical
flow from previous frames to the current, thereby
yielding multiple plausible estimates. It then
fuses the complementary information carried by
these estimates into a new optical flow field. At
the time of submission, our method ranks first
among published flow methods in the MPI Sintel
and KITTI 2015 benchmarks.

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.
