# Object Detection on MS COCO 2018 (test-dev) Source: [Object Detection on MS COCO 2018 (test-dev)]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:22:38.304Z Evaluation of Object Detection performance on the test-dev split of the MS COCO 2018 dataset, measured using standard COCO Average Precision metrics (AP, AP50, AP75, and size-specific APs). 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 | Object Detection | | Dataset (including any stated split) | MS COCO 2018 (test-dev) | | Metric | AP | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 4 of 4 | | 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 - [AP](): Higher is better; unit: PERCENT. - [AP50](): Higher is better; unit: PERCENT. - [AP75](): Higher is better; unit: PERCENT. - [AP Small](): Higher is better; unit: PERCENT. - [AP Medium](): Higher is better; unit: PERCENT. - [AP Large](): Higher is better; unit: PERCENT. ## Recorded results | Method | AP | Result date | Report paper | | --- | --- | --- | --- | | Mask R-CNN w/ CARAFE | 38.8 | Not recorded | 68fa66911e209131cea10f20 | | Faster R-CNN w/ CARAFE | 38.1 | Not recorded | 68fa66911e209131cea10f20 | | Mask R-CNN | 37.8 | Not recorded | 68fa66911e209131cea10f20 | | Faster R-CNN | 36.9 | Not recorded | 68fa66911e209131cea10f20 | ### Mask R-CNN w/ CARAFE AP: 38.8.
