Evaluation of Open-set Person Re-identification performance using the C3 protocol on the test split of the CUHK03 dataset, typically measured using mAP and Rank-1 accuracy (R1).

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 | Open-set Person Re-identification |
| Dataset (including any stated split) | CUHK03 C3 (test) |
| Metric | mAP |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 12 of 12 |
| 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

- [mAP](<https://www.sota2.com/research/sota/open-set-person-re-identification-on-cuhk03-c3-test.md?metric=mAP>): Higher is better; unit: PERCENT.

- [R1](<https://www.sota2.com/research/sota/open-set-person-re-identification-on-cuhk03-c3-test.md?metric=R1>): Higher is better; unit: PERCENT.
