How Split4D Reconstructs 4D Dynamic Scenes Without Video Segmentation

Split4D introduces a novel paradigm for 4D scene reconstruction that eliminates the need for video segmentation by leveraging single‑frame 2D masks, a freetime feature learning strategy, streaming sampling, and 3D tracking regularization, achieving high‑quality, object‑level decoupled representations across complex dynamic scenarios.

How DP-Recon Uses Diffusion Models to Reconstruct 3D Scenes from Sparse Photos

DP-Recon leverages generative diffusion priors and a visibility‑guided SDS loss to achieve high‑fidelity, compositional 3D scene reconstruction from extremely sparse images, delivering superior geometry, texture, and text‑driven editing capabilities demonstrated on benchmark datasets and real‑world indoor scenarios.
