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.
