| `source` | `str` | `None` | Specifies the source directory for images or videos. Supports file paths and URLs. |
| `persist` | `bool` | `False` | Enables persistent tracking of objects between frames, maintaining IDs across video sequences. |
| `tracker` | `str` | `botsort.yaml` | Specifies the tracking algorithm to use, e.g., `bytetrack.yaml` or `botsort.yaml`. |
| `conf` | `float` | `0.3` | Sets the confidence threshold for detections; lower values allow more objects to be tracked but may include false positives. |
| `iou` | `float` | `0.5` | Sets the [Intersection over Union](https://www.ultralytics.com/glossary/intersection-over-union-iou) (IoU) threshold for filtering overlapping detections. |
| `classes` | `list` | `None` | Filters results by class index. For example, `classes=[0, 2, 3]` only tracks the specified classes. |
| `verbose` | `bool` | `True` | Controls the display of tracking results, providing a visual output of tracked objects. |
