Evaluation of Image Super-resolution performance using the Urban100 dataset, reporting PSNR across eight specific degradation conditions (clean, blur, noise, JPEG compression, and their combinations).

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 | Image Super-resolution |
| Dataset (including any stated split) | Urban100 |
| Metric | PSNR (Overall) |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 46 of 46 |
| 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

- [PSNR (Overall)](<https://www.sota2.com/research/sota/image-super-resolution-on-urban100-psnr-variants.md?metric=PSNR%20(Overall)>): Higher is better; unit: SCALAR.

- [PSNR (clean)](<https://www.sota2.com/research/sota/image-super-resolution-on-urban100-psnr-variants.md?metric=PSNR%20(clean)>): Higher is better; unit: SCALAR.

- [PSNR (blur)](<https://www.sota2.com/research/sota/image-super-resolution-on-urban100-psnr-variants.md?metric=PSNR%20(blur)>): Higher is better; unit: SCALAR.

- [PSNR (noise)](<https://www.sota2.com/research/sota/image-super-resolution-on-urban100-psnr-variants.md?metric=PSNR%20(noise)>): Higher is better; unit: SCALAR.

- [PSNR (jpeg)](<https://www.sota2.com/research/sota/image-super-resolution-on-urban100-psnr-variants.md?metric=PSNR%20(jpeg)>): Higher is better; unit: SCALAR.

- [PSNR (blur+noise)](<https://www.sota2.com/research/sota/image-super-resolution-on-urban100-psnr-variants.md?metric=PSNR%20(blur%2Bnoise)>): Higher is better; unit: SCALAR.

- [PSNR (blur+jpeg)](<https://www.sota2.com/research/sota/image-super-resolution-on-urban100-psnr-variants.md?metric=PSNR%20(blur%2Bjpeg)>): Higher is better; unit: SCALAR.

- [PSNR (noise+jpeg)](<https://www.sota2.com/research/sota/image-super-resolution-on-urban100-psnr-variants.md?metric=PSNR%20(noise%2Bjpeg)>): Higher is better; unit: SCALAR.
