Inputs (9)
| Name | Type | Default | Description |
|---|---|---|---|
| fill_hole_area | INT | 160–1000 | Maximum area (in pixels) of holes to fill in masks. 0 disables hole filling. Useful for cleaning up mask interiors. |
| assoc_iou_thresh | FLOAT | 0.100–1 | IOU threshold for detection-to-track association (0.0-1.0). Lower = more lenient matching for maintaining track continuity. |
| det_nms_thresh | FLOAT | 0.100–1 | IOU threshold for Non-Maximum Suppression (0.0-1.0). Lower = more aggressive duplicate removal. 0.0 disables NMS. |
| hotstart_unmatch_thresh | INT | 30–999 | Number of unmatched frames before removing a track (hotstart heuristic). Higher = more tolerant of temporary occlusions. Set to 999 to effectively disable. |
| hotstart_dup_thresh | INT | 30–999 | Number of overlapping frames before removing duplicate tracks. Higher = more tolerant of temporary overlaps. Set to 999 to effectively disable. |
| init_trk_keep_alive | INT | 0-10–50 | Initial keep-alive counter for new tracks. Higher = tracks survive longer without matching detections. Recommended: 5-20 for robust tracking. |
| hotstart_delay | INT | 00–200 | Delay (in frames) before applying hotstart removal heuristics. Useful to let tracks stabilize in early frames. Set to 999 to disable hotstart entirely. |
| decrease_keep_alive_empty | BOOLEAN | true | Whether empty masks (zero area predictions) decrease the keep-alive counter. Disable for more lenient tracking. |
| suppress_unmatched_globally | BOOLEAN | true | Whether to suppress tracks with keep_alive <= 0 globally (True) or only during hotstart period (False). CRITICAL: Set to True to actually remove dead tracks! |
