SC-GS: Sparse-Controlled Gaussian Splatting for Editable Dynamic Scenes

Reconstructed Motion Control Panel l l l Edited Motion Control Points & 3D Gaussians across View & Time (b) Dynamic View Synthesis (c) Motion Editing (a) Input Images Fix Drag Figure 1. Given (a) an image sequence from a monocular dynamic video, we propose to represent the motion with a set of sparse control points, which can be used to drive 3D Gaussians for high-fidelity rendering. Our approach enables both (b) dynamic view synthesis and (c) motion editing due to the motion representation based on sparse control points.
