Ruijie Lu (陆睿杰)

I'm currently a second-year Ph.D student at Peking University (PKU), supervised by Prof. Gang Zeng. Before that, I received by Bachelor's degree at Peking University in July 2023. My research interests lie in 3D Computer Vision, especially scene understanding, generation and reconstruction.

Research

	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.
	Superpoint Gaussian Splatting for Real-Time High-Fidelity Dynamic Scene Reconstruction Diwen Wan, Ruijie Lu, Gang Zeng, ICML 2024 [Paper] [Code] [Project Page] We introduce SP-GS, which utilizes superpoint to represent neighboring Gaussians with similar motion patterns for efficiency.
	InTeX: Interactive Text-to-Texture Synthesis via Unified Depth-aware Inpainting Jiaxiang Tang, Ruijie Lu, Hang Zhou, Xiang Wen, Xiaokang Chen, Diwen Wan, Gang Zeng, Jingdong Wang, Ziwei Liu, arXiv [Paper] [Code] [Project Page] We introduce InTeX, which utilizes depth-aware inpainting to synthesize high-quality textures from text prompts for objects.
