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 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.
