Method Description:
We present EFSNet, a stereo matching network
engineered for an optimal balance between accuracy
and real-time performance. Its core innovation is a
hybrid 2D-3D aggregation module that
synergistically fuses information from parallel
cost representations to capture both robust context
and fine spatial details. The network also
incorporates a dual-path refinement strategy that
specializes in textured and untextured regions to
maximize accuracy. Benchmark comparisons
demonstrate that EFSNet delivers a superior
combination of speed and computational efficiency,
establishing it as among the fastest state-of-the-
art methods.

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.
