ChronoGS: Disentangling Invariants and Changes in Multi-Period Scenes

Zhongtao Wang, Jiaqi Dai, Qingtian Zhu, Yilong Li, Mai Su, Fei Zhu +5

CVPR 2026

Multi-period image collections are common in real-world applications. Cities are re-scanned for mapping, construction sites are revisited for progress tracking, and natural regions are monitored for environmental change. Such data form multi-period scenes, where geometry and appearance evolve. Recon

PCGS: Deblurring 3D Gaussian Splatting with Patch Comparison

Yilong Li, Bo Pang, Zhongtao Wang, Mai Su, Yisong Chen, Chengwei Pan +3

ICML 2026poster

Recent neural methods, such as 3D Gaussian Splatting, have achieved state-of-the-art rendering quality and speed. However, these methods frequently encounter challenges in regions with overlapping Gaussians, leading to blurring and artifacts in the rendered images. We observed that widely used view-…
