Single Image to Textured 3D Object Generation in Frequency Domain: From Theory to Pipeline
Qisen Wang, Yifan Zhao, Jia Li
Single-view 3D reconstruction, also known as image-to-3D, is a persistently challenging task due to the extreme lack of information. Recently, diffusion models pre-trained on large…
WorldTree: Towards 4D Dynamic Worlds from Monocular Video using Tree-Chains
Qisen Wang, Yifan Zhao, Jia Li
Dynamic reconstruction has achieved remarkable progress, but there remain challenges in monocular input for more practical applications. The prevailing works attempt to construct e…
ChronosObserver: Taming 4D World with Hyperspace Diffusion Sampling
Qisen Wang, Yifan Zhao, Peisen Shen +2
Although prevailing camera-controlled video generation models can produce cinematic results, lifting them directly to the generation of 3D-consistent and high-fidelity time-synchro…
How to Use Diffusion Priors under Sparse Views?
Qisen Wang, Yifan Zhao, Jiawei Ma +1
Novel view synthesis under sparse views has been a long-term important challenge in 3D reconstruction. Existing works mainly rely on introducing external semantic or depth priors t…
