Control4D: Efficient 4D Portrait Editing with Text

Shao, Ruizhi, Sun, Jingxiang, Peng, Cheng et al.

Understand

We introduce Control4D, an innovative framework for editing dynamic 4D portraits using text instructions.

  • Our method addresses the prevalent challenges in 4D editing, notably the inefficiencies of existing 4D representations and the inconsistent editing effect caused by diffusion-based editors.
  • We first propose GaussianPlanes, a novel 4D representation that makes Gaussian Splatting more structured by applying plane-based decomposition in 3D space and time.
  • This enhances both efficiency and robustness in 4D editing.
