PRISM: Feed-Forward Single-Image 3D Reconstruction via Geometric Warp-Residual Modeling
Summary
PRISM is a novel feed-forward framework designed for single-image 3D scene reconstruction, addressing a fundamental challenge in computer vision. It overcomes the practical deployment limitations of iterative diffusion sampling inherent in existing camera-controlled video diffusion models. PRISM achieves this by decomposing multi-view latent prediction into a parameter-free geometric prior and a learned residual correction, eliminating the need for diffusion sampling during inference. The framework employs a two-stage training strategy, combining latent supervised distillation for geometric generalization and perceptual fine-tuning for appearance quality optimization. Extensive experiments on three benchmarks demonstrate PRISM delivers competitive reconstruction quality while dramatically reducing inference time to only 36 seconds per scene.
Key takeaway
For Computer Vision Engineers developing real-time 3D reconstruction applications, PRISM offers a compelling alternative to diffusion-based methods. Its feed-forward architecture dramatically reduces inference time to 36 seconds per scene, making it suitable for deployment-constrained environments. You should evaluate PRISM for projects requiring rapid single-image 3D scene generation without significant quality compromise.
Key insights
PRISM enables fast, feed-forward single-image 3D reconstruction by correcting geometric warps with a learned residual.
Principles
- Geometric forward warping covers the majority of target view data
- Decomposition into a prior and residual improves efficiency
- Two-stage training aids generalization from synthetic data
Method
Decompose multi-view latent prediction into a parameter-free geometric prior and a learned residual correction. Train in two stages: latent supervised distillation and perceptual fine-tuning.
In practice
- Apply geometric warping as a strong initial prior
- Use residual learning for fine-grained corrections
- Employ two-stage training for synthetic data generalization
