Point'n Move: Interactive Scene Object Manipulation on Gaussian
  Splatting Radiance Fields
Jiajun Huang Hongchuan Yu
We propose Point'n Move, a method that achieves interactive scene object
manipulation with exposed region inpainting. Interactivity here further comes
from intuitive object selection and real-time editing. To achieve this, we
adopt Gaussian Splatting Radiance Field as the scene representation and fully
leverage its explicit nature and speed advantage. Its explicit representation
formulation allows us to devise a 2D prompt points to 3D mask dual-stage
self-prompting segmentation algorithm, perform mask refinement and merging,
minimize change as well as provide good initialization for scene inpainting and
perform editing in real-time without per-editing training, all leads to
superior quality and performance. We test our method by performing editing on
both forward-facing and 360 scenes. We also compare our method against existing
scene object removal methods, showing superior quality despite being more
capable and having a speed advantage.
