DecoRec: Decomposed 3D Scene Reconstruction from Single-View Images via Object-Level Diffusion

Cheng Lin, Jianyi Zheng, Jia Pan, Junhui Hou, Peng Wang, Xiaoxiao Long, Xin Li, Yuan Liu, Yuhan Ping

DecoRec reconstructs 3D scenes from single-view images by diffusing objects individually then refining their merge.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

DecoRec facilitates high-quality single-view scene reconstruction in both geometry and novel synthesis by reconstructing individual objects separately with diffusion models and merging them via a refinement pipeline using differentiable rendering and diffusion guidance.

C2weakest assumption

That high-quality per-object reconstructions can be merged without introducing major geometric or appearance inconsistencies that the subsequent refinement pipeline cannot reliably correct.

C3one line summary

DecoRec decomposes single-view 3D scene reconstruction into per-object diffusion reconstructions followed by a differentiable rendering and diffusion-guided merging pipeline.
