Prompt-SID demonstrates outstanding results across synthetic, real-world, and fluorescence imaging datasets. It consistently surpasses state-of-the-art self-supervised methods like B2U and NBR2NBR, often showing 0.2-0.5 dB PSNR improvement. The method also outperforms traditional supervised methods in many scenarios, highlighting its strong generalization and effectiveness in preserving image details without requiring clean training data.
| Method | Key Features | Prompt-SID Advantages |
|---|---|---|
| Traditional Supervised (e.g., FFDNet) | Requires paired noisy/clean data; High performance with ideal data. |
|
| Self-Supervised (e.g., N2V, NBR2NBR) | Blind-spot networks or downsampled pairs; Avoids identity mapping. |
|
| Diffusion Models (general) | High generative capability; Can introduce randomness. |
