Sparse-View 4D Gaussian Splatting via Spatiotemporal Priors and Generative Assistance

Shengqi Wang, Zhengxian Yang, Kaiwen Tian et al. · 2026

We present a 4D Gaussian Splatting framework for the Sparse-View Track of the SIGGRAPH Asia 2026 Volumetric Video Challenge, which requires dynamic scene reconstruction from only six cameras with wide baselines. To achieve robust dynamic reconstruction under such sparse views, our framework integrates three components. …

TTRSD: Test-Time Reinforcement Learning with Self-Distillation for Vision-Language Models

Shuning Wang, Zhiheng Wu, Xun Zhou et al. · 2026

Test-time reinforcement learning enables vision-language models (VLMs) to adapt using unlabeled inputs. However, repeated sampling under fixed visual conditions can reinforce shared perceptual errors, while sequence-level rewards fail to isolate visual perception the foundational bottleneck that anchors multimodal reas …
