# Near-duplicate detection on Copydays crop 50% INRIA Source: [Near-duplicate detection on Copydays crop 50% INRIA]() Collection index: [llms.txt]() Data updated: 2026-02-26T06:09:20.726Z Evaluation of Near-duplicate detection performance on the Copydays crop 50% INRIA dataset, reporting mAP. 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 | Near-duplicate detection | | Dataset (including any stated split) | Copydays crop 50% INRIA | | Metric | mAP | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 18 of 18 | | 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](): Higher is better; unit: PERCENT. ## Recorded results | Method | mAP | Result date | Report paper | | --- | --- | --- | --- | | BoW | 100 | Not recorded | 68fa61e71e209131ce9f6965 | | BoW | 100 | Not recorded | 68fa61e71e209131ce9f6965 | | C-SVDDNet | 100 | Not recorded | 68fa61e71e209131ce9f6965 | | MSRV+C-SVDDNet | 100 | Not recorded | 68fa61e71e209131ce9f6965 | | MSRV+C-SVDDNet | 100 | Not recorded | 68fa61e71e209131ce9f6965 | | MSRV+K-meansNet | 99.7 | Not recorded | 68fa61e71e209131ce9f6965 | | FV | 98.7 | Not recorded | 68fa61e71e209131ce9f6965 | | C-SVDDNet | 98.1 | Not recorded | 68fa61e71e209131ce9f6965 | | MSRV+K-meansNet | 97.9 | Not recorded | 68fa61e71e209131ce9f6965 | | VLAD | 97.7 | Not recorded | 68fa61e71e209131ce9f6965 | | C-SVDD | 97.4 | Not recorded | 68fa61e71e209131ce9f6965 | | K-meansNet | 96.8 | Not recorded | 68fa61e71e209131ce9f6965 | | K-means | 95.2 | Not recorded | 68fa61e71e209131ce9f6965 | | K-meansNet | 94.3 | Not recorded | 68fa61e71e209131ce9f6965 | | VLAD | 94.2 | Not recorded | 68fa61e71e209131ce9f6965 | | C-SVDD | 93.8 | Not recorded | 68fa61e71e209131ce9f6965 | | FV | 92.7 | Not recorded | 68fa61e71e209131ce9f6965 | | K-means | 91.5 | Not recorded | 68fa61e71e209131ce9f6965 | ### BoW mAP: 100.
