Evaluation of image quality metrics (PSNR, SSIM, FID, CLIP score) applied to images generated by Stable Diffusion models, specifically focusing on assessing the quality impact of watermarking techniques.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Watermarked Image Quality Assessment |
| Dataset (including any stated split) | Stable Diffusion |
| Metric | SSIM |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 3 of 3 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [SSIM](<https://www.sota2.com/research/sota/watermarked-image-quality-assessment-on-stable-diffusion.md?metric=SSIM>): Higher is better; unit: PERCENT.

- [PSNR](<https://www.sota2.com/research/sota/watermarked-image-quality-assessment-on-stable-diffusion.md?metric=PSNR>): Higher is better; unit: SCALAR.

- [MSSIM](<https://www.sota2.com/research/sota/watermarked-image-quality-assessment-on-stable-diffusion.md?metric=MSSIM>): Higher is better; unit: PERCENT.

- [CLIP Score](<https://www.sota2.com/research/sota/watermarked-image-quality-assessment-on-stable-diffusion.md?metric=CLIP%20Score>): Higher is better; unit: SCALAR.

- [FID](<https://www.sota2.com/research/sota/watermarked-image-quality-assessment-on-stable-diffusion.md?metric=FID>): Lower is better; unit: SCALAR.
