Diet Engine: A real-time food nutrition assistant system for personalized dietary guidance
I developed a real-time, AI-powered smartphone app that acts as a personal nutritionist right in your pocket. By simply snapping a photo of a meal, the app uses advanced deep learning—specifically YOLOv8 and Convolutional Neural Networks (CNNs)—to instantly recognize the food and calculate its exact nutritional breakdown, achieving an impressive 86% classification accuracy. To make the experience truly user-centric, I also integrated an NLP-driven chatbot that offers tailored meal plans, fitness
