Method Description:
CHRNet is a compact stereo-matching architecture
designed to achieve a strong accuracy-runtime
trade-off for deployment on resource-constrained
edge devices. The network utilizes a Cross-
Directional Aggregation Feature Extractor (CDAE)
to efficiently capture elongated structures and
directional cues. Cost volumes are constructed
using a Huber-based Cost-Volume Builder (HCVB)
with scale-aware normalization to suppress
outliers while preserving sharp discontinuities.
Finally, a Deformable-style Residual Refinement
(DSRR) module provides efficient, locally adaptive
corrections by predicting per-pixel sampling
offsets. Note: This work is currently under review
in IEEE Transactions on Multimedia (TMM).

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.
