Deployment

How to Use the Model

To use the trained model, follow these steps:

1. Load the Model:

   from ultralytics import YOLO
   
   # Load the model
   model = YOLO("yolo11m_urchin_trained.pt")
   

Limitations

The model was trained on a mix of open source images. It may not generalize well to other environments or non-marine scenarios. Additionally, environmental variations, occlusions, or poor lighting may affect performance.

Additional Notes:

Dataset Sources:

• Two datasets were combined to improve model robustness, allowing the model to adapt to varying lighting and water conditions. Ethical Considerations:
• The detection results should be validated before using them for critical applications. The model’s performance in new environments might vary, and it may have biases if certain types of sea urchins were underrepresented in the training datasets.
