Revolutionizing View Synthesis with Adaptive Diffusion Denoising and Pixel-Weighting Techniques
Researchers from Aalto University, System 2 AI, and Finnish Center for Artificial Intelligence FCAI have developed ViewFusion, an advanced generative method for view synthesis. It employs diffusion denoising and pixel-weighting to combine informative input views, addressing previous limitations. ViewFusion is trainable across diverse scenes, adapts to varying input views, and generates high-quality results even in challenging conditions. Though it doesn’t create a 3D scene embedding and has slower inference, it outperforms existing methods on the NMR dataset.
Key Features of ViewFusion
- Adaptive diffusion denoising and pixel-weighting techniques
- Trainable across diverse scenes
- Adapts to varying input views
- Generates high-quality results in challenging conditions
ViewFusion’s approach to view synthesis achieves top-tier performance in key metrics like PSNR, SSIM, and LPIPS. Evaluated on the diverse NMR dataset, it consistently matches or surpasses current state-of-the-art methods. Its adaptability shines through its capability to seamlessly incorporate varying numbers of pose-free views during training and inference stages, consistently delivering high-quality results regardless of input view count. Leveraging its generative nature, ViewFusion produces realistic views comparable to or surpassing existing state-of-the-art techniques.
