World-Env: Leveraging World Model as a Virtual Environment for VLA Post-Training

Junjin Xiao, Yandan Yang, Xinyuan Chang +5

Vision-Language-Action (VLA) models trained via imitation learning suffer from significant performance degradation in data-scarce scenarios due to their reliance on large-scale dem…

Structure-Guided Diffusion Models for High-Fidelity Portrait Shadow Removal

Wanchang Yu, Qing Zhang, Rongjia Zheng +1

We present a diffusion-based portrait shadow removal approach that can robustly produce high-fidelity results. Unlike previous methods, we cast shadow removal as diffusion-based in…

DNF-Intrinsic: Deterministic Noise-Free Diffusion for Indoor Inverse Rendering

Rongjia Zheng, Qing Zhang, Chengjiang Long +1

Recent methods have shown that pre-trained diffusion models can be fine-tuned to enable generative inverse rendering by learning image-conditioned noise-to-intrinsic mapping. Despi…
