CGGT: Curve-Grounded Geometry Transformer for 3D Parametric Curve Reconstruction

CGGT is proposed, a Curve-Grounded Geometry Transformer that directly grounds 3D-consistent 2D curve instances in the image space from sparse, unposed multi-view images, demonstrating its potential for practical CAD-style wireframe reconstruction from unconstrained visual inputs.

From dark flash images to relightable 3D scenes with photometric stereo priors

A photometric stereo problem of input images by a grouping-and-merging strategy that enables reconstruction and relighting of dark scenes and outperforms state-of-the-art approaches in decomposition, geometry, and relighting.
