	DreamReward-X: Boosting High-Quality 3D Generation with Human Preference Alignment Fangfu Liu, Junliang Ye, Yikai Wang, Hanyang Wang, Zhengyi Wang, Zhu Jun, Yueqi Duan Submitted to IEEE Transactions on Pattern Analysis and Machine Intelligence, TPAMI, 2024 [arXiv] [Code] [Project Page] We present a comprehensive framework, coined DreamReward++, where we introduce a reward-aware noise sampling strategy to unleash text-driven diversity during the generation process while ensuring human preference alignment. Grounded by theoretical proof and extensive experiment comparisons, our method successfully generates high-fidelity and diverse 3D results with significant boosts in prompt alignment with human intention. Our results demonstrate the great potential for learning from human feedback to improve 3D generation.
	ReconX: Reconstruct Any Scene from Sparse Views with Video Diffusion Model Fangfu Liu, Wenqiang Sun, Hanyang Wang, Yikai Wang, Sun Haowen, Junliang Ye, Jun Zhang, Yueqi Duan Arxiv*, 2024 [arXiv] [Code] [Project Page] In this paper, we propose ReconX, a novel 3D scene reconstruction paradigm that reframes the ambiguous reconstruction challenge as a temporal generation task. The key insight is to unleash the strong generative prior of large pre-trained video diffusion models for sparse-view reconstruction.
	DreamReward: Aligning Human Preference in Text-to-3D Generation Junliang Ye, Fangfu Liu, Qixiu Li, Zhengyi Wang, Yikai Wang, Xinzhou Wang, Yueqi Duan , Jun Zhu European Conference on Computer Vision (ECCV), 2024 [arXiv] [Code] [Project Page] We present a comprehensive framework, coined DreamReward, to learn and improve text-to-3D models from human preference feedback.
	AnimatableDreamer: Text-Guided Non-rigid 3D Model Generation and Reconstruction with Canonical Score Distillation Xinzhou Wang, Yikai Wang, Junliang Ye, Zhengyi Wang, Fuchun Sun, Pengkun Liu, Ling Wang, Kai Sun, Xintong Wang, Bin He European Conference on Computer Vision (ECCV), 2024 [arXiv] [Code] [Project Page] We propose ANIMATABLEDREAMER, a framework with the capability to generate generic categories of non-rigid 3D models.
