Evaluation of JPEG image restoration performance on the ImageNet dataset, specifically targeting artifacts introduced by Quality Factor 2 compression, measured using PSNR.

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 | JPEG Restoration (QF=2) |
| Dataset (including any stated split) | ImageNet |
| Metric | PSNR |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| 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](<https://www.sota2.com/research/sota/jpeg-restoration-qf-2-on-imagenet.md?metric=PSNR>): Higher is better; unit: SCALAR.
