A new arXiv survey, "Reconstructing the Dynamic World: A Representation-Centric View of 4D Scene Reconstruction," with 16 authors including Ming-Hsuan Yang, Qi Tian, Nicu Sebe, and Jianfei Cai, offers a unified perspective on recovering evolving geometry, appearance, and motion of dynamic scenes:
- Organizes existing methods by scene representation, temporal modeling, reconstruction pipeline, and optimization objectives, spanning NeRF and 3D Gaussian Splatting lines
- Analyzes how design choices affect geometric fidelity, appearance consistency, motion representation, and efficiency
- Consolidates datasets and evaluation metrics, flags weaknesses in current experimental practice, and outlines open challenges
