# FathomNet Megalodon Detector
|
| 11 |
+
|
| 12 |
+
## Model Details
|
| 13 |
+
|
| 14 |
+
- Trained by researchers at the [Monterey Bay Aquarium Research Institute](https://www.mbari.org/) (MBARI).
|
| 15 |
+
- Ultralytics [YOLOv8x](https://github.com/ultralytics/ultralytics)
|
| 16 |
+
- Object detection model
|
| 17 |
+
- Fine-tuned to detect 1 class, called 'object', using all FathomNet localizations
|
| 18 |
+
|
| 19 |
+
## Intended Use
|
| 20 |
+
|
| 21 |
+
- Post-process video and images collected by marine researchers
|
| 22 |
+
- Can be used to build a localized set of training images, when neither training data nor a model exists for the imagery being analyzed
|
| 23 |
+
|
| 24 |
+
## Factors
|
| 25 |
+
|
| 26 |
+
- Distribution shifts related to sampling platform, camera parameters, illumination, and deployment environment are expected to impact model performance
|
| 27 |
+
- Evaluation was performed on an IID subset of available training data as well as out-of-distribution data
|
| 28 |
+
|
| 29 |
+
## Metrics
|
| 30 |
+
|
| 31 |
+
- [Normalized confusion matrix](plots/confusion_matrix_normalized.png), [precision-recall curve](plots/PR_curve.png), and [F1-confidence curve](plots/F1_curve.png) were evaluated at test time
|
| 32 |
+
- [email protected] = 0.782
|
| 33 |
+
|
| 34 |
+
## Training and Evaluation Data
|
| 35 |
+
|
| 36 |
+
- All publicly-available data on [FathomNet](https://fathomnet.org/)
|
| 37 |
+
|
| 38 |
+
## Deployment
|
| 39 |
+
|
| 40 |
+
1. Clone this repository
|
| 41 |
+
2. In an environment with the [`ultralytics` Python package](https://github.com/ultralytics/ultralytics) installed, run:
|
| 42 |
+
|
| 43 |
+
```bash
|
| 44 |
+
yolo predict model=best.pt
|
| 45 |
+
```
