Implicit 4D Gaussian Splatting for Fast Motion with Large Inter-Frame Displacements
Seung-gyeom Kim, Areum Kim, Yongjae Yoo, Sukmin Yun
Recent 4D Gaussian Splatting (4DGS) methods often fail under fast motion with large inter-frame displacements, where Gaussian attributes are poorly learned during training, and fast-moving objects are often lost from the reconstruction. In this work, we introduce Spatiotemporal P…
