Evaluation of Camouflaged Object Detection performance on the specific 4121-image test split of the NC4K dataset, reporting specialized metrics including Sm, Em, Fw\_beta, and MAE.

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 | Camouflaged Object Detection |
| Dataset (including any stated split) | NC4K 4121 (test) |
| Metric | Sm |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 1 of 1 |
| 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

- [Sm](<https://www.sota2.com/research/sota/camouflaged-object-detection-on-nc4k-4121-test.md?metric=Sm>): Higher is better; unit: SCALAR.

- [Em](<https://www.sota2.com/research/sota/camouflaged-object-detection-on-nc4k-4121-test.md?metric=Em>): Higher is better; unit: SCALAR.

- [Fw\_beta](<https://www.sota2.com/research/sota/camouflaged-object-detection-on-nc4k-4121-test.md?metric=Fw_beta>): Higher is better; unit: SCALAR.

- [MAE](<https://www.sota2.com/research/sota/camouflaged-object-detection-on-nc4k-4121-test.md?metric=MAE>): Lower is better; unit: SCALAR.
