Lift4D: A Method for Single-View 4D Dynamic Scene Reconstruction Using Gaussian Splatting

Summary

This article presents Lift4D, a novel methodology for reconstructing 4D (3D + time) dynamic scenes from single-view video input. The approach combines a single-view reconstruction prior with causal latent propagation and a Gaussian SplatDecoder to generate per-frame 3D reconstructions. It also incorporates an occlusion-aware appearance loss function to handle visibility challenges in real-world dynamic scenes. The work focuses on enabling 4D reconstruction "in-the-wild" from minimal input (single-view video), which is a significant advancement over traditional multi-view reconstruction methods.
