Method Description:
HCCVStereo implements a hierarchical correlation
cost volume approach for stereo matching that
constructs multi-scale correlation pyramids
between stereo image pairs. The method combines
group-normalized correlation computation with
probabilistic weighting to improve matching
accuracy, while employing adaptive hierarchical
sampling across different pyramid levels for
robust disparity estimation. The framework enables
efficient cost volume construction through
bilinear interpolation and multi-level correlation
aggregation.
Parameters:
lr=0.0002, batch_size=8

Detailed Results

This page provides detailed results for the method(s) selected. For each of the first 20 test images, the number of erroneous pixels at all thresholds is depicted in the table. Underneath, the left input image, the disparity / end-point error map and the estimated (and interpolated) disparity / optical flow map are shown. The error map scales linearly between 0 (black) and >=5 (white) pixels error. Red denotes all occluded pixels, falling outside the image boundaries. The false color map is scaled to the largest ground truth disparity / flow value.
