Ruijie Lu (陆睿杰)

Currently, I'm a third-year Ph.D student at Peking University (PKU), supervised by Prof. Gang Zeng. Before that, I received my Bachelor's degree at Peking University in July 2023. My research interests lie in multimodal understanding and generation, while I also have a background in 3D vision.

	DreamArt: Generating Interactable Articulated Objects from a Single Image Ruijie Lu, Yu Liu, Jiaxiang Tang, Junfeng Ni, Yuxiang Wang, Diwen Wan, Gang Zeng, Yixin Chen, Siyuan Huang SIGGRAPH Asia 2025 [Paper] [Project Page] We introduce DreamArt, a three-stage pipeline for generating interactable articulated assets from a single image, comprising part-segmented mesh generation, articulation video generation, and articulated asset construction.
	TACO: Taming Diffusion for in-the-wild Video Amodal Completion Ruijie Lu, Yixin Chen, Yu Liu, Jiaxiang Tang, Junfeng Ni, Diwen Wan, Gang Zeng, Siyuan Huang ICCV 2025 [Paper] [Code] [Data] [Project Page] We introduce TACO, which repurposes pre-trained video diffusion models for Video Amodal Completion (VAC), facilitating downstream tasks like reconstruction. The key insight lies in the data curation and progressive training strategy.
	MOVIS: Enhancing Multi-Object Novel View Synthesis for Indoor Scenes Ruijie Lu, Yixin Chen, Junfeng Ni, Baoxiong Jia, Yu Liu, Diwen Wan, Gang Zeng, Siyuan Huang CVPR 2025 [Paper] [Code] [Data] [Project Page] We introduce MOVIS, which repurposes pre-trained diffusion models for multi-object level novel view synthesis (NVS) in indoor scenes. The key insight lies in incorporating a structure-aware noise scheduler and an auxiliary mask prediction task under novel views.
	RoomTex: Texturing Compositional Indoor Scenes via Iterative Inpainting Qi Wang, Ruijie Lu, Xudong Xu, Jingbo Wang, Michael Yu Wang, Bo Dai, Gang Zeng, Dan Xu ECCV 2024 [Paper] [Code] [Project Page] We introduce RoomTex, which utilizes image inpainting to synthesize high-quality and style-consistent textures of multiple styles given scene meshes.
