The document describes a proposed web-based nutrition and diet assistance system using machine learning. The system aims to accurately identify foods from images using a convolutional neural network (CNN) model, calculate the nutritional content of the foods, determine the user's BMI, and provide personalized diet recommendations. The system uses techniques like pre-processing, region proposal networks, feature extraction, and CNNs to classify foods, retrieve nutritional data, and suggest diets tailored for the user's BMI and food choices. The goal is to help users conveniently track their nutrition intake and maintain a balanced diet for better health outcomes.
