V4D: Voxel for 4D Novel View Synthesis. (arXiv:2205.14332v2 [cs.CV] UPDATED)

Neural radiance fields have made a remarkable breakthrough in the novel view
synthesis task at the 3D static scene. However, for the 4D circumstance (e.g.,
dynamic scene), the performance of the existing method is still limited by the
capacity of the neural network, typically in a multilayer perceptron network
(MLP). In this paper, we utilize 3D Voxel to model the 4D neural radiance
field, short as V4D, where the 3D voxel has two formats. The first one is to
regularly …
