cd cropedgeai
pip install uv
uv sync

For development: uv sync --group dev

Quick Start

1. Data Preparation

from cropedgeai.dataset import WeedCropDatasetLoader

loader = WeedCropDatasetLoader("path/to/weed-crop-dataset")
dataset = loader()

print(f"Loaded {len(dataset)} annotations")
print(f"Classes: {dataset['class_name'].unique()}")

2. Exploratory Data Analysis

from cropedgeai.eda import WeedCropEDA, WeedCropVisualizer

eda = WeedCropEDA(dataset, dataset_name="My Dataset")
stats = eda.dataset_distribution()

visualizer = WeedCropVisualizer(eda)
visualizer.plot_class_balance()
visualizer.plot_spatial_distribution()

3. Dataset Splitting & Augmentation

from cropedgeai.dataset import DatasetSplitter, DatasetAugmenter

splitter = DatasetSplitter(dataset, validation_size=0.15, test_size=0.15, output_dir="./processed", organize_files=True)
train, val, test = splitter()

augmenter = DatasetAugmenter(train, "./augmented", "./processed")
augmented_dataset = augmenter(
    run_overlay=True,
    run_closeup=True,
    overlay_images=1000,
    weeds_per_image=5
)

4. Model Training & Benchmarking

from cropedgeai.experiments import YOLOExperiment

experiment = YOLOExperiment("config/baseline_experiment.yaml")
results = experiment()

5. Hyperparameter Optimization

from cropedgeai.experiments import YOLOHyperparameterOptimizer

optimizer = YOLOHyperparameterOptimizer("config/hpo_yolo11n.yaml")
hpo_results = optimizer()

6. Edge Deployment Optimization

from cropedgeai.experiments import YOLONCNNHyperparameterOptimizer

ncnn_optimizer = YOLONCNNHyperparameterOptimizer("config/ncnn_hpo.yaml")
results = ncnn_optimizer()

ncnn_path = ncnn_optimizer.export_ncnn(best_size) # Check results to confirm `best_size`

7. Batch Inference

cropedgeai model.pt input_folder/ output_folder/ \
  --conf-threshold 0.35 \
  --img-size 640 \
  --stats-csv detections.csv

from cropedgeai.inference import YOLOBatchProcessor

processor = YOLOBatchProcessor(
    model_path="best.pt",
    input_folder="test_images/",
    output_folder="results/",
    stats_csv_file="detection_stats.csv",
    conf_threshold=0.35
)
processor()
