Evaluation of Shadow Removal performance on the test split of the SRD original dataset, measured using PSNR, SSIM, and RMSE across shadow, non-shadow, and all image regions.

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 | Shadow Removal |
| Dataset (including any stated split) | SRD original (test) |
| Metric | RMSE (Shadow Region) |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 10 of 10 |
| 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

- [RMSE (Shadow Region)](<https://www.sota2.com/research/sota/shadow-removal-on-srd-original-test.md?metric=RMSE%20(Shadow%20Region)>): Lower is better; unit: SCALAR.

- [PSNR (Shadow Region)](<https://www.sota2.com/research/sota/shadow-removal-on-srd-original-test.md?metric=PSNR%20(Shadow%20Region)>): Higher is better; unit: SCALAR.

- [SSIM (Shadow Region)](<https://www.sota2.com/research/sota/shadow-removal-on-srd-original-test.md?metric=SSIM%20(Shadow%20Region)>): Higher is better; unit: PERCENT.

- [PSNR (Non-Shadow Region)](<https://www.sota2.com/research/sota/shadow-removal-on-srd-original-test.md?metric=PSNR%20(Non-Shadow%20Region)>): Higher is better; unit: SCALAR.

- [SSIM (Non-Shadow Region)](<https://www.sota2.com/research/sota/shadow-removal-on-srd-original-test.md?metric=SSIM%20(Non-Shadow%20Region)>): Higher is better; unit: PERCENT.

- [RMSE (Non-Shadow Region)](<https://www.sota2.com/research/sota/shadow-removal-on-srd-original-test.md?metric=RMSE%20(Non-Shadow%20Region)>): Lower is better; unit: SCALAR.

- [PSNR (All Image)](<https://www.sota2.com/research/sota/shadow-removal-on-srd-original-test.md?metric=PSNR%20(All%20Image)>): Higher is better; unit: SCALAR.

- [SSIM (All Image)](<https://www.sota2.com/research/sota/shadow-removal-on-srd-original-test.md?metric=SSIM%20(All%20Image)>): Higher is better; unit: PERCENT.

- [RMSE (All Image)](<https://www.sota2.com/research/sota/shadow-removal-on-srd-original-test.md?metric=RMSE%20(All%20Image)>): Lower is better; unit: SCALAR.
