We propose a method for dynamic scene reconstruction using deformable 3D
Gaussians that is tailored for monocular video. Building upon the efficiency of
Gaussian splatting, our approach extends the representation to accommodate
dynamic elements via a deformable set of Gaussians residing in a canonical
space, and a time-dependent deformation field defined by a multi-layer
perceptron (MLP). Moreover, under the assumption that most natural scenes have
large regions that remain static, we allow the MLP to focus its
representational power by additionally including a static Gaussian point cloud.
The concatenated dynamic and static point clouds form the input for the
Gaussian Splatting rasterizer, enabling real-time rendering. The differentiable
pipeline is optimized end-to-end with a self-supervised rendering loss. Our
method achieves results that are comparable to state-of-the-art dynamic neural
radiance field methods while allowing much faster optimization and rendering.
