Beyond Simple Image Recognition: Building a Precise AI Nutritionist with GPT-4o and Segment Anything (SAM)

This tutorial provides a comprehensive guide on how to build an advanced computer vision system using Segment Anything Model (SAM) and GPT-4o to estimate the nutritional value of meals with high precision. Below is a summary and key points from your detailed explanation:

Summary

The goal is to create a pipeline that can accurately identify different food items in a meal, estimate their portion sizes, and provide precise nutritional information by leveraging SAM for segmentation and GPT-4o for semantic understanding.

Key Points

1. Segment Anything Model (SAM)

   • Used for identifying and segmenting individual food components within an image.
   • Helps distinguish overlapping foods like rice and curry on a plate.

2. GPT-4o Integration

   • Utilizes GPT-4o's capabilities to analyze segmented areas and provide detailed nutritional breakdowns.
   • Ensures accurate identification of food types, reducing the risk of hallucination (e.g., mistaking chili oil for tomato sauce).

3. Visual RAG Pattern

   • Combines AI-generated labels with a PostgreSQL database containing verified nutritional profiles.
   • Enhances accuracy by cross-referencing AI predictions with real-world data.

4. SQL Query Strategy
