Gaussian-Flow: 4D Reconstruction with Dynamic 3D Gaussian Particle

Figure 1. Dynamic reconstruction results of the proposed Gaussian-Flow on the monocular D-NeRF [30] and HyperNeRF Dataset [28] (left) and the multi-view Plenoptic Dataset [18] (right). Our method achieves a 5⇥ faster training and rendering speed compared with the per-frame 3DGS modeling and significantly outperforms previous methods in novel view rendering quality.
