Running time:0.05 s
Environment:GPU @ 1.5 Ghz (Python)

Method Description:
We have developed a lightweight stereo matching
network that achieves higher matching precision
without a substantial increase in computational
cost, by enhancing the aggregation process of the
cost volume and optimizing the post-processing of
disparity estimation based on the confidence of
the initial disparity estimates.
Parameters:
We finetune the pre-trained Scene Flow model on the
mixed KITTI 2012 and KITTI 2015 training sets for
400 epochs.

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.
