# Semi-supervised Video Object Segmentation on YTVOS 2019 (val) Source: [Semi-supervised Video Object Segmentation on YTVOS 2019 (val)]() Collection index: [llms.txt]() Data updated: 2026-05-19T12:03:36.213Z Evaluation of Semi-supervised Video Object Segmentation performance on the validation split of the YTVOS 2019 dataset, reporting Jaccard (J) and F-scores (F) for overall (G), union (u), and seen/unseen categories (s/u). 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 | Semi-supervised Video Object Segmentation | | Dataset (including any stated split) | YTVOS 2019 (val) | | Metric | Overall Jaccard (G) | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 28 of 28 | | 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 - [Overall Jaccard (G)](): Higher is better; unit: PERCENT. - [Jaccard (Seen)](): Higher is better; unit: PERCENT. - [F-Score (Seen)](): Higher is better; unit: PERCENT. - [Jaccard (Union)](): Higher is better; unit: PERCENT. - [F-Score (Union)](): Higher is better; unit: PERCENT. - [J&F Score](): Higher is better; unit: PERCENT. ## Recorded results | Method | Overall Jaccard (G) | Result date | Report paper | | --- | --- | --- | --- | | SAM 2 | 89.3 | Not recorded | 68fa756f1e209131cea67e54 | | SAM 2 | 88.8 | Not recorded | 68fa756f1e209131cea67e54 | | SAM 2 | 88.6 | Not recorded | 68fa756f1e209131cea67e54 | | SAM 2 | 88.2 | Not recorded | 68fa756f1e209131cea67e54 | | SAM 2 | 88 | Not recorded | 68fa756f1e209131cea67e54 | | Cutie-base+ | 87.5 | Not recorded | 68fa756f1e209131cea67e54 | | Joint Former | 87.4 | Not recorded | 68fa756f1e209131cea67e54 | | SAM 2 | 87.4 | Not recorded | 68fa756f1e209131cea67e54 | | Cutie-base | 87 | Not recorded | 68fa756f1e209131cea67e54 | | ISVOS | 86.3 | Not recorded | 68fa756f1e209131cea67e54 | | SwinB-DeAOT-L | 86.1 | Not recorded | 68fa756f1e209131cea67e54 | | XMem | 85.6 | Not recorded | 68fa756f1e209131cea67e54 | | DEVA | 85.4 | Not recorded | 68fa756f1e209131cea67e54 | | SwinB-AOT-L | 84.5 | Not recorded | 68fa756f1e209131cea67e54 | | SimVOS-B | 84.2 | Not recorded | 68fa756f1e209131cea67e54 | | STCN | 82.7 | Not recorded | 68fa756f1e209131cea67e54 | | RDE | 81.9 | Not recorded | 68fa756f1e209131cea67e54 | ### SAM 2 Overall Jaccard (G): 89.3.
