AI-Powered Image Captioning App

Project Overview

An innovative image captioning application leveraging Salesforce's BLIP (Bootstrapped Language-Image Pretraining) model to generate human-like descriptions of uploaded images. The system demonstrates the practical application of state-of-the-art AI in creating accessible and intuitive image understanding tools.

Technical Architecture

Frontend (ReactJS + Vite)

  • Modern, responsive user interface
  • Real-time image upload and preview
  • Efficient state management
  • Fast development workflow with Hot Module Replacement
  • Axios for robust API communication

Backend (Flask)

  • RESTful API endpoints for image processing
  • Efficient image handling and validation
  • Seamless integration with AI models
  • Scalable architecture for future enhancements
