Workflow Name
Image Object Detection and Annotation Workflow Based on Google Gemini 2.0
Key Features and Highlights
This workflow leverages the multimodal AI capabilities of Google Gemini 2.0 to achieve precise recognition and localization of target objects within specified images. By using prompt-based (textual) inputs, it intelligently detects specific objects in images (e.g., rabbits) and automatically draws corresponding bounding boxes. A key highlight is its support for natural language–based object detection requests, enhancing the flexibility and intelligence of image analysis.
Core Problems Addressed
Traditional image object detection typically requires pre-trained models and lacks the ability to customize detection targets on demand. This workflow calls the Google Gemini 2.0 API, enabling users to describe desired detection objects directly in natural language. It solves issues of limited detection categories and cumbersome filtering, while automatically normalizing coordinates and rendering bounding boxes, greatly simplifying subsequent processing steps.
Application Scenarios
- Intelligent image content annotation and search
- Rapid identification and highlighting of specific objects within images
- Security monitoring and anomaly detection of objects
- Visual data analysis and report generation
- Business scenarios requiring fast, on-demand detection of specific image elements
Main Process Steps
- Download Test Image: Obtain target image resources via an HTTP request node.
- Extract Image Information: Retrieve image width and height to prepare for coordinate conversion.
- Call Gemini 2.0 Object Detection API: Send requests containing image data and text prompts to receive object bounding box coordinates.
- Extract and Normalize Coordinates: Parse the API’s normalized coordinates and scale them according to the actual image dimensions.
- Draw Bounding Boxes: Use the “Edit Image” node to render bounding boxes of detected objects on the original image.
- Display and Validate: Visually verify detection results through the rendered bounding boxes.
