Disparity Has a Sign: Stereo Matching Beyond the Zero-Disparity Plane
Jian Shi, Xinge Yang, Chaoyang Wang +2
Modern stereo matching models fail when disparity crosses zero, with end-point error (EPE) rising by 4.6-37. Yet stereoscopic content, from cinema 3D to VR, routinely conta…

Any Resolution Any Geometry: From Multi-View To Multi-Patch
Wenqing Cui, Zhenyu Li, Mykola Lavreniuk +4
Joint estimation of surface normals and depth is essential for holistic 3D scene understanding, yet high-resolution prediction remains difficult due to the trade-off between preser…

Geometry without Position? When Positional Embeddings Help and Hurt Spatial Reasoning
Jian Shi, Michael Birsak, Wenqing Cui +2
This paper revisits the role of positional embeddings (PEs) within vision transformers (ViTs) from a geometric perspective. We show that PEs are not mere token indices but effectiv…
