Method Description:
LiteDynStereo is a dual-branch stereo matching
method that integrates monocular structural priors
with binocular geometric constraints. It
adaptively skips redundant basic stereo updates
based on disparity convergence, with a stopping
threshold calibrated by disparity variance and
iteration progress. Seven cross-modal refinement
iterations are retained after the basic-update
stage. Reprojection-error-derived confidence
coefficients modulate the geometric conditions
during refinement.
Parameters:
Minimum basic iterations: 10
Maximum basic iterations: 25
Cross-modal refinement iterations: 7
Base convergence threshold: 0.05
Batch size: 1
Framework: Python/PyTorch
Hardware: NVIDIA RTX 3090

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.
