💻 Usage

Training the Model

from model_microscopic import MicroscopicOrganismClassifier

# Initialize classifier
classifier = MicroscopicOrganismClassifier(num_classes=5, img_size=128)

# Prepare data
train_gen, val_gen = classifier.prepare_data('data/train', 'data/val')

# Train model
history = classifier.train(train_gen, val_gen, epochs=15)

# Evaluate
class_names = list(train_gen.class_indices.keys())
classifier.evaluate_model(val_gen, class_names)

# Save model
classifier.model.save('microscopic_organism_classifier.h5')

Running the Web App

streamlit run app.py

Visit http://localhost:8501 in your browser.

Single Image Prediction

# Predict single image
predicted_class, confidence, probabilities = classifier.predict_single_image(
    'path/to/image.jpg',
    class_names=['Amoeba', 'Diatom', 'Euglena', 'Paramecium', 'Volvox']
)

print(f"Predicted: {predicted_class} (Confidence: {confidence:.2f}%)")
