Object Detection with Gemini API

Leveraging AI for Open-Vocabulary Detection, Attribute Recognition, and Scene Understanding

Introduction

Object detection is a fundamental task in computer vision, enabling AI models to identify and localize objects within an image. This notebook demonstrates how to use the Gemini API for object detection, including:

🔹 Single & Multi-Class Object Detection

🔹 Attribute-Based Recognition (e.g., Detecting red umbrellas, white dresses)

🔹 Negative Object Detection (Ensuring absent objects are not falsely identified)

🔹 World Knowledge for Object Identification (e.g., Recognizing Dog Breeds)

🔹 Reading Handwritten Text & Detecting Objects Referenced in Text

🔹 Spatial Reasoning & Scene Understanding

This work showcases how Large Vision-Language Models (VLMs) can analyze, reason, and interact with images using advanced AI techniques.

Final Summary & Key Takeaways

This notebook successfully demonstrates Object Detection with Gemini API using Open-Vocabulary Vision-Language Models (VLMs).

🔹 Object Detection in Various Scenarios ✔ Open-vocabulary object detection ✔ Multi-class detection with attribute filtering (e.g., red umbrellas, white dresses) ✔ Negative detection (ensuring absent objects are ignored)

🔹 Advanced AI Capabilities ✔ World Knowledge Integration (Identifying dog breeds) ✔ Handwritten Text-Based Object Detection ✔ Spatial Reasoning & Scene Understanding

🔹 Applications in Real-World Use Cases ✔ Automated object counting and classification ✔ AI-powered visual question answering (VQA) ✔ Security & surveillance analysis ✔ Retail and e-commerce product recognition

Future Enhancements:

  • Combine Gemini’s Vision API with object tracking for real-time applications.
  • Extend VQA (Visual Question Answering) capabilities for deeper scene understanding.
  • Explore text-conditioned object retrieval (e.g., “Find the blue backpack in the image”).
