DN-4DGS: Denoised Deformable Network with Temporal-Spatial Aggregation for Dynamic Scene Rendering

Understand

Dynamic scenes rendering is an intriguing yet challenging problem.

• Although current methods based on NeRF have achieved satisfactory performance, they still can not reach real-time levels.
• Recently, 3D Gaussian Splatting (3DGS) has garnered researchers attention due to their outstanding rendering quality and real-time speed.
• Therefore, a new paradigm has been proposed: defining a canonical 3D gaussians and deforming it to individual frames in deformable fields.
