Evaluation of model performance on lossless image compression applied to the validation split of the Open Images dataset, measured using bits per sub-pixel (bpsp).

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 | Lossless Image Compression |
| Dataset (including any stated split) | Open Images (val) |
| Metric | BPSP |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 7 of 7 |
| 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

- [BPSP](<https://www.sota2.com/research/sota/lossless-image-compression-on-open-images-val.md?metric=BPSP>): Lower is better; unit: SCALAR.
