ZDPShift weights — Disparity Has a Sign

Checkpoints for Disparity Has a Sign: Stereo Matching Beyond the Zero-Disparity Plane. Each backbone comes as a pair:

Suffix	Meaning
*_zs.pth	the publicly released checkpoint, unchanged (zero-shot baseline; cannot output negative disparity)
*_ours.pth	the same backbone fine-tuned on horizontally translated SceneFlow only (no benchmark data, no new parameters); estimates signed disparity on both sides of the screen plane

Backbone	Files	Notes
FoundationStereo	fs_zs.pth, fs_ours.pth, fs_cfg.yaml	signed cost volume, d_neg=64, d_pos=192
IGEV-Stereo	igev_zs.pth, igev_ours.pth	signed cost volume, d_neg=64, d_pos=192
RAFT-Stereo	raft_zs.pth, raft_ours.pth	symmetric correlation range
StereoAnyVideo	sav_zs.pth, sav_ours.pth, video_depth_anything_vits.pth	the VDA file is the frozen monocular prior the model constructs
DynamicStereo	dynamic_zs.pth, dynamic_ours.pth
BiDAStereo	bida_zs.pth, bida_ours.pth

The ZDPShift benchmark itself is evaluation-only: none of these models has seen it. Code, evaluation scripts and the demo: https://github.com/shijianjian/ZDPShift · https://huggingface.co/spaces/shijianjian/ZDPShift · dataset: https://huggingface.co/datasets/shijianjian/ZDPShift
