General description
Ultralytics' Yolo V8 medium model fined tuned for coffee cherry detection using the Croppie coffee dataset.
This algorithm provides automated cherry count from RGB pictures. Takes as input a picture and returns the cherry count by class.
The predicted numerical classes correspond to the following cherry types:
{0: "dark_brown_cherry", 1: "green_cherry", 2: "red_cherry", 3: "yellow_cherry"}
Examples of use:
- yield estimates
- ripeness detection
Limitations: This algorithm does not include correction of cherry occlusion.
Note: the low visibility/unsure class was not used for model fine tuning

Demonstration
Assuming you are in the scripts folder, you can run python3 test_script.py. This script saves the annotated image in ../images/annotated_1688033955437.jpg.
Make sure that the Python packages found in requirements.txt are installed. In case they are not, simply run pip3 install -r requirements.txt.
A live demonstration is freely accesible here.
Training metrics
The model has been trained using the custom YOLO class found in ./scripts/custom_YOLO.py. The custom YOLO class can be exactly used as the original YOLO class. The hyperparameters used during the training can be found in ./scripts/args.yaml.
