Usage

Installation

pip install tensorflow keras

Load and Use the Model

import tensorflow as tf
from tensorflow import keras
from PIL import Image
import numpy as np

# Load the model
model = keras.models.load_model('best.keras')

# Prepare image
image = Image.open('path/to/potato_leaf.jpg')
image = image.resize((224, 224))
image_array = np.array(image) / 255.0
image_array = np.expand_dims(image_array, axis=0)

# Make prediction
predictions = model.predict(image_array)
class_names = ['Early Blight', 'Late Blight', 'Healthy']
predicted_class = class_names[np.argmax(predictions)]
confidence = np.max(predictions)

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

Intended Use

This model is intended for:

• Primary Use: Classification of potato leaf diseases in agricultural applications
• Supported Use Cases:
  • Automated disease detection systems
  • Agricultural advisory systems
  • Precision farming applications
  • Research and baseline comparisons

Limitations

• Dataset Scope: Trained exclusively on PlantVillage dataset (controlled environment); performance may vary significantly on real-world field images
• Controlled Conditions: Model trained on images with consistent lighting and clean backgrounds; may underperform on field images with varying conditions
• Class Focus: Only covers 3 potato disease classes (Early Blight, Late Blight, Healthy); cannot detect other potato diseases or crop diseases
• Perfect Metrics Caution: 100% accuracy on test set may indicate small test set or dataset characteristics; validate on real-world data before deployment
• Image Requirements: Requires clear, well-lit leaf images; heavily obscured or extremely blurry images may reduce accuracy
• Environmental Sensitivity: Best performance in controlled or semi-controlled environments similar to PlantVillage dataset conditions
