Closely Interactive Human Reconstruction with Proxemics and Physics-Guided Adaption

1 code implementation CVPR 2024 Buzhen Huang, Chen Li, Chongyang Xu, Liang Pan, Yangang Wang, Gim Hee Lee

Knowledge NeRF: Few-shot Novel View Synthesis for Dynamic Articulated Objects

1 code implementation31 Mar 2024 Wenxiao Cai, Xinyue Lei, Xinyu He, Junming Leo Chen, Yangang Wang

To clearly reconstruct dynamic scenes, we propose a new framework by considering two frames at a time. We pretrain a NeRF model for an articulated object. When articulated objects moves, Knowledge NeRF learns to generate novel views at the new state by incorporating past knowledge in the pretrained NeRF model with minimal observations in the present state.

4D Myocardium Reconstruction with Decoupled Motion and Shape Model

1 code implementation ICCV 2023 Xiaohan Yuan, Cong Liu, Yangang Wang

Estimating the shape and motion state of the myocardium is essential in diagnosing cardiovascular diseases. However, cine magnetic resonance (CMR) imaging is dominated by 2D slices, whose large slice spacing challenges inter-slice shape reconstruction and motion acquisition. To address this problem, we propose a 4D reconstruction method that decouples motion and shape, which can predict the inter-/intra- shape and motion estimation from a given sparse point cloud sequence obtained from limited slices.
