Method Description:
MoCha-V2's results in the original manuscript were
removed from the list, this is the result of a re-
upload version.MoCha-V2 introduces the Motif
Correlation Graph (MCG) to capture recurring
textures, which are referred to as “motifs”
within feature channels. These motifs reconstruct
geometric structures and are learned in a more
interpretable way. Subsequently, we integrate
features from multiple frequency domains through
wavelet inverse transformation. The resulting
motif features are utilized to restore geometric
structures in the stereo matching process.

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.
