# Crowd Instance Segmentation on UCF-QNRF (40% labeled) Source: [Crowd Instance Segmentation on UCF-QNRF (40% labeled)]() Collection index: [llms.txt]() Data updated: 2026-03-18T08:22:50.319Z Evaluation of Crowd Instance Segmentation performance on the 40% labeled subset of the UCF-QNRF dataset, measured using IoU@0.5. 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 | Crowd Instance Segmentation | | Dataset (including any stated split) | UCF-QNRF (40% labeled) | | Metric | IoU@0.5 | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 5 of 5 | | 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 - [IoU@0.5](): Higher is better; unit: PERCENT. ## Recorded results | Method | IoU@0.5 | Result date | Report paper | | --- | --- | --- | --- | | XMask | 29.7 | Not recorded | 69ba31af0636e5bf4afc0a30 | | XMask | 27.8 | Not recorded | 69ba31af0636e5bf4afc0a30 | | FastSAM | 23.3 | Not recorded | 69ba31af0636e5bf4afc0a30 | | FastSAM | 21.3 | Not recorded | 69ba31af0636e5bf4afc0a30 | | point only | 20.7 | Not recorded | 69ba31af0636e5bf4afc0a30 | ### XMask IoU@0.5: 29.7.
