DIScene: Object Decoupling and Interaction Modeling for Complex Scene Generation
Xiao-Lei Li, Haodong Li, Hao-Xiang Chen, Tai-Jiang Mu, Shi-Min Hu

SIGGRAPH Asia 2024
Paper / Video

DIScene is capable of generating complex 3D scene with decoupled objects and clear interactions. Leveraging a learnable Scene Graph and Hybrid Mesh-Gaussian representation, we get 3D scenes with superior quality. DIScene can also flexibly edit the 3D scene by changing interactive objects or their attributes, benefiting diverse applications.

Bi-TTA: Bidirectional Test-Time Adapter for Remote Physiological Measurement
Haodong Li, Hao Lu, Ying-Cong Chen

ECCV 2024
arXiv / Paper / Project Page

We introduce Bi-TTA, a method that leverages spatial and temporal consistency for appropriate self-supervision, coupled with novel prospective and retrospective adaptation strategies, enabling superior adaptation ability of pre-trained rPPG models to the target domain using only unannotated, instance-level target data.

LucidDreamer: Towards High-Fidelity Text-to-3D Generation via Interval Score Matching

CVPR 2024 Highlight
arXiv / Paper / Github GitHub stars / Demo / Video

We present LucidDreamer, a text-to-3D generation framework, to distill high-fidelity textures and shapes from pretrained 2D diffusion models with a novel Interval Score Matching objective and an advanced 3D distillation pipeline. Together, we achieve superior 3D generation results with photorealistic quality in a short training time.
