Method Description:
• We designed a confidence guided motion
aggregation module to propagate the motion features
from high-quality areas to low-quality areas
globally guided by confidence, improving the
accuracy of optical flow in the low quality areas.
• We designed a large kernel block for motion
feature extraction and residual flow generation to
increase the receptive field during flow
optimization iterations, further promoting global
flow aggregation with limited computational cost.
• Our LKCMA achieved competitive optical flow
results on multiple benchmarks.
Parameters:
\mul=1

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.
