Methodology
1. Data Collection:
– Utilize publicly available datasets, such as the PlantVillage dataset, and collaborate with agricultural universities and organizations to gather diverse samples.
– Ensure the dataset includes images of various crops (e.g., tomato, potato, grape) and a wide range of diseases (e.g., blight, rust, powdery mildew).
2. Data Preprocessing:
– Implement image preprocessing techniques:
– Resizing: Standardize image dimensions to a fixed size for uniformity.
– Normalization: Scale pixel values to a range (e.g., 0-1) to aid in model training.
– Augmentation: Apply transformations such as rotation, flipping, and zooming to artificially expand the dataset.
3. Feature Extraction:
– Use feature extraction techniques tailored for image data:
– Traditional methods like color histograms and texture features.
– Deep learning techniques such as CNNs to automatically extract features from images, leveraging pre-trained models like VGG16 or ResNet.
4. Model Development:
– Implement various supervised machine learning algorithms:
– Support Vector Machine (SVM): For its effectiveness in high-dimensional spaces.
– Decision Trees: For interpretable decision making.
– Convolutional Neural Networks (CNNs): For end-to-end learning from raw image data.
– Experiment with ensemble methods to increase the robustness of predictions.
5. Model Evaluation:
– Split the dataset into training, validation, and testing sets.
– Perform hyperparameter tuning using grid search or random search to optimize model performance.
– Evaluate models based on accuracy, precision, recall, F1 score, and confusion matrix to understand classification effectiveness.
6. User Interface Development:
– Design and develop a web or mobile application that allows users to:
– Upload images of plant leaves.
– Receive analysis results indicating the presence of diseases.
– Access helpful resources on disease management.
– Ensure the interface is intuitive and provides clear feedback to the user.
7. Deployment:
– Select a suitable platform (e.g., AWS, Heroku) for deploying the application.
– Implement APIs for model inference to ensure scalability and accessibility in real-time.
– Consider offline capabilities for areas with limited internet access.
