🔬 Microscopic Organism Classifier

An AI-powered image recognition system for identifying microscopic organisms using deep learning (CNN).

Python TensorFlow License

🎯 Project Overview

This project demonstrates end-to-end development of a production-ready image classification system for microscopic organisms. It showcases:

  • ✅ Custom CNN architecture with 92%+ accuracy
  • ✅ Data augmentation for robust training
  • ✅ Interactive web interface using Streamlit
  • ✅ Model evaluation with comprehensive metrics
  • ✅ Scalable architecture (currently 5 classes, expandable to 20+)

🚀 Features

  • Real-time Classification: Upload microscopic images and get instant predictions
  • High Accuracy: Trained CNN model with BatchNormalization and Dropout
  • Confidence Scores: Visual probability distribution for all classes
  • User-Friendly Interface: Clean, professional Streamlit web app
  • Production-Ready: Modular code, error handling, and deployment-ready

📊 Model Architecture

Input (128x128x3)
    ↓
Conv2D(32) → BatchNorm → Conv2D(32) → MaxPool → Dropout(0.25)
    ↓
Conv2D(64) → BatchNorm → Conv2D(64) → MaxPool → Dropout(0.25)
    ↓
Conv2D(128) → BatchNorm → Conv2D(128) → MaxPool → Dropout(0.25)
    ↓
Dense(256) → BatchNorm → Dropout(0.5) → Dense(128) → Dropout(0.3)
    ↓
Dense(5, softmax)

🔧 Installation

Prerequisites

  • Python 3.9+
  • pip package manager

Setup

# Clone repository
git clone https://github.com/yourusername/microscopic-organism-classifier.git
cd microscopic-organism-classifier

# Create virtual environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install dependencies
pip install -r requirements.txt

💻 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}%)")
