Animate124: Animating One Image to 4D Dynamic Scene

no code implementations24 Nov 2023 Yuyang Zhao, Zhiwen Yan, Enze Xie, Lanqing Hong, Zhenguo Li, Gim Hee Lee

We introduce Animate124 (Animate-one-image-to-4D), the first work to animate a single in-the-wild image into 3D video through textual motion descriptions, an underexplored problem with significant applications.

OD-NeRF: Efficient Training of On-the-Fly Dynamic Neural Radiance Fields

no code implementations24 May 2023 Zhiwen Yan, Chen Li, Gim Hee Lee

Dynamic neural radiance fields (dynamic NeRFs) have demonstrated impressive results in novel view synthesis on 3D dynamic scenes.
