# Instrument Segmentation on CholecSeg8k M2CAI-Seg (last episode) Source: [Instrument Segmentation on CholecSeg8k M2CAI-Seg (last episode)]() Collection index: [llms.txt]() Data updated: 2026-04-06T08:29:35.557Z Evaluation of Instrument Segmentation performance specifically on the M2CAI-Seg (last episode) subset of the CholecSeg8k dataset, utilizing specialized IoU metrics (LH IoU, Gr IoU, etc.) alongside Boundary/Foreground Transfer metrics (BWT, FWT). 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 | Instrument Segmentation | | Dataset (including any stated split) | CholecSeg8k M2CAI-Seg (last episode) | | Metric | Gr IoU | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 17 of 17 | | 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 - [Gr IoU](): Higher is better; unit: PERCENT. - [LH IoU](): Higher is better; unit: PERCENT. - [Cl IoU](): Higher is better; unit: PERCENT. - [Sc IoU](): Higher is better; unit: PERCENT. - [Ir IoU](): Higher is better; unit: PERCENT. - [SB IoU](): Higher is better; unit: PERCENT. - [Bi IoU](): Higher is better; unit: PERCENT. - [New Class IoU](): Higher is better; unit: PERCENT. - [All IoU](): Higher is better; unit: PERCENT. - [BWT (Boundary Transfer Error)](): Lower is better; unit: SCALAR. - [FWT (Foreground Transfer Error)](): Lower is better; unit: SCALAR. ## Recorded results | Method | Gr IoU | Result date | Report paper | | --- | --- | --- | --- | | Joint-T | 80.88 | Not recorded | 69d33de27d0172140ec73557 | | Ours (SAM) | 80.85 | Not recorded | 69d33de27d0172140ec73557 | | Ind-T | 79.4 | Not recorded | 69d33de27d0172140ec73557 | | Ind-T | 74.11 | Not recorded | 69d33de27d0172140ec73557 | | Ours (DeepLabv3+) | 66.18 | Not recorded | 69d33de27d0172140ec73557 | | CAT-SD | 62.39 | Not recorded | 69d33de27d0172140ec73557 | | PLOP | 58.98 | Not recorded | 69d33de27d0172140ec73557 | | RCIL | 55.89 | Not recorded | 69d33de27d0172140ec73557 | | LWF | 54.7 | Not recorded | 69d33de27d0172140ec73557 | | SI | 54.3 | Not recorded | 69d33de27d0172140ec73557 | | EWF | 53.96 | Not recorded | 69d33de27d0172140ec73557 | | Seq-F | 53.67 | Not recorded | 69d33de27d0172140ec73557 | | ILT | 52.52 | Not recorded | 69d33de27d0172140ec73557 | | RASD | 51.54 | Not recorded | 69d33de27d0172140ec73557 | | LISM | 51.06 | Not recorded | 69d33de27d0172140ec73557 | | CoinSeg | 48.3 | Not recorded | 69d33de27d0172140ec73557 | | MiB | 47.79 | Not recorded | 69d33de27d0172140ec73557 | ### Joint-T Gr IoU: 80.88.
