Environment:RTX 2080Ti GPU with 2.5GHz processor

Method Description:
We propose an effective architecture that leverages
deformable kernel convolution as a single-pass
refinement module, and empirically demonstrate its
superiority. To better understand the function of
deformable convolution and exploit it for depth
completion, we further systematically investigate a
variety of representative strategies. Our study
reveals that, different from prior work, deformable
convolution needs to be applied on an estimated
depth map with a relatively high density for better
performance.

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 Sparsity Invariant CNNs (THREEDV 2017), 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 Sparsity Invariant CNNs (THREEDV 2017), 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.
