🏥 Medical Image Analysis Tool

An AI-powered medical image analysis application using advanced detection models and large language models for medical image interpretation.

Features

• Advanced Object Detection: Uses RF-DETR (Real-time Fine-grained Detection Transformer) for precise object detection
• Medical AI Analysis: Integrates MedGemma, a specialized medical vision-language model
• Interactive Interface: Built with Gradio for easy web-based interaction
• Configurable Thresholds: Adjustable confidence thresholds for detection sensitivity
• Model Size Selection: Choose between MedGemma 4B (faster) or 27B (more accurate) models
• GPU Acceleration: Optimized for GPU usage when available with 4-bit quantization
• Automatic Model Downloads: Models download automatically from Hugging Face Hub

Models Used

• RF-DETR Medium: State-of-the-art object detection model
• MedGemma 4B/27B: Medical-specialized vision-language models for analysis and descriptions
  • 4B model: Faster inference, lower memory usage
  • 27B model: Higher accuracy, requires more resources

Usage

1. Upload Image: Click on the image upload area or drag and drop a medical image
2. Adjust Settings:
   • Use the confidence threshold slider to control detection sensitivity
   • Select model size (4B for speed, 27B for accuracy)
3. Analyze: Click "Analyze Image" to run the AI analysis
4. View Results: See the annotated image with detected objects and AI-generated descriptions

Installation & Setup

This application is designed to run on Hugging Face Spaces. The following files are required:

• app.py - Main application file (optimized for Spaces)
• requirements.txt - Python dependencies
• packages.txt - System packages
• README.md - This documentation

Model Loading

RF-DETR Model:

• Upload your trained rf-detr-medium.pth file to the Space
• The application will automatically find and load it

MedGemma Models:

• Models download automatically from Hugging Face Hub on first use
• No manual installation required
• Choose between 4B (faster) or 27B (more accurate) models

Space Configuration

For optimal performance, configure your Space settings:

• Hardware: GPU (T4 minimum, A100 recommended for 27B models)
• Storage: Enable persistent storage for model caching
• Timeout: 30+ minutes for large model downloads

Technical Details

• Framework: PyTorch + Transformers
• Interface: Gradio
• Computer Vision: OpenCV, PIL, Supervision
• Hardware: Optimized for both CPU and GPU inference

Performance Tips

• Model Selection: Use MedGemma 4B for faster processing or 27B for higher accuracy
• Confidence Thresholds: Higher values reduce false positives but may miss subtle findings
• GPU Acceleration: The application automatically uses GPU acceleration when available
• Memory Optimization: Uses 4-bit quantization to reduce memory usage
• Model Caching: Models are cached after first load for faster subsequent analyses

Limitations

• Requires significant computational resources for optimal performance
• Best suited for medical imaging applications
• Results should be verified by qualified medical professionals

Development

To run locally:

pip install -r requirements.txt
python app.py

Note: For local development, you'll need to:

1. Install the RF-DETR package or ensure it's available
2. Place your rf-detr-medium.pth file in the project directory
3. Models will download automatically on first run
