European Conference on Computer Vision (ECCV) 2026

We propose MoGe4D, a framework that tightly couples 3D geometry reconstruction with motion generation to synthesize dynamic 4D scenes from a single image, together with the TrajScene-60K dataset of dense 4D point trajectories and a diffusion-based 4D trajectory generator.

IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR) 2026

We unify image generation and generated-image detection within a single architecture, where a symbiotic multi-modal attention mechanism and a detector-informed alignment objective allow the two tasks to improve each other in a co-evolutionary loop.

Skyra: AI-Generated Video Detection via Grounded Artifact Reasoning

Yifei Li, Wenzhao Zheng#, Yanran Zhang, Runze Sun, Yu Zheng, Lei Chen, Jie Zhou, Jiwen Lu (# corresponding author)

IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR) 2026

We present Skyra, a multimodal large language model that detects AI-generated videos by grounding its decisions in human-perceivable visual artifacts, enabled by the ViF-CoT-4K dataset and a two-stage SFT + reinforcement learning training strategy.
