Casual Flash Lighting for Gaussian Splat Inverse Rendering
Jiamin Xu, Dongheng Wei, Jiarong Zhao +4
Recovering geometry, materials, and lighting from photographs is highly ambiguous when only static illumination is available. Active-lighting setups reduce the ambiguity but requir…
Robust Global Structure-from-Motion via View Graph Pruning
Jiamin Xu, Lixing Yao, Weichen Dai +4
Structure-from-Motion (SfM) aims to estimate camera poses and reconstruct 3D structures from a collection of unordered images. Compared with incremental SfM, global SfM achieves be…
WildShadowRemover: In-the-Wild Video Shadow Removal via Detail-Preserving Video Diffusion Models
Jiamin Xu, Cong Wang, Zheng Dong +4
Video shadow removal in the wild remains challenging due to complex illumination, diverse shadow appearances, and limited training data. Despite its importance to numerous vision a…
Detail-Preserving Latent Diffusion for Stable Shadow Removal
Jiamin Xu, Yuxin Zheng, Zelong Li +4
Achieving high-quality shadow removal with strong generalizability is challenging in scenes with complex global illumination. Due to the limited diversity in shadow removal dataset…
OmniSR: Shadow Removal under Direct and Indirect Lighting
Jiamin Xu, Zelong Li, Yuxin Zheng +4
Shadows can originate from occlusions in both direct and indirect illumination. Although most current shadow removal research focuses on shadows caused by direct illumination, shad…
