How to Generate Image Embeddings Using JavaScript

In modern web and AI applications, working with image data is becoming more common. From search engines to recommendation systems, the need to understand images semantically is growing fast. One key tool for this is image embeddings, turning an image into a vector that captures its content and meaning.

In this article, you'll learn how to generate image embeddings using JavaScript and the Eden AI API. We'll cover how to set up your Eden AI account, install dependencies, and write JavaScript code to access embedding data through a unified API.

‍

What Are Image Embeddings

Image embeddings transform images into dense vector embeddings that capture semantic meaning — so images that look alike or share similar content produce similar vectors. These embeddings are powerful tools for tasks such as:

• Image similarity search
• Image clustering
• Training image classification models
• Content-based recommendation systems

Rather than relying on raw pixel data, these embeddings provide more meaningful features for algorithms to work with.

Eden AI simplifies access to a variety of image embedding models (from providers like Google, AWS, and others) through a single, unified API. This eliminates the need for separate integrations and allows you to easily test, compare, and switch between providers without modifying your code.

How to Generate Image Embeddings

Get Access to Eden AI

1. Sign Up for an Eden AI Account: To begin using the Image Embeddings API, create an account on Eden AI. After registration, you’ll receive an API key that unlocks access to many AI services.

2. Access Image Technologies: After logging in, navigate to the image section of the platform.

3. Select Image Embeddings: Choose the Image Embeddings feature.

Test Models Live on Eden AI

Before integrating in code, you can test embedding models directly on the Eden AI platform to compare providers and understand outputs.

Implementing Image Embeddings in JavaScript

Install the requests Module

To install Axios, use npm:

npm install axios

‍

Prepare the Code

Here’s how you can make a request to generate image embeddings using Eden AI:

import requests

response = requests.post(
    "https://api.edenai.run/v2/image/embeddings/",
    json={
        "providers": ["google"],
        "representation": "document",
        "file_url": "https://example.com/image.jpg"  # Replace with your image URL
    },
    headers={
        "accept": "application/json",
        "content-type": "application/json",
        "authorization": "Bearer <your_api_key>"  # Replace with your Eden AI token
    }
)

print(response.json())

Explanation of the Code

• axios.post: Sends a POST request to Eden AI’s image embedding endpoint.
  
• Request Body:
  
  • providers: Specifies the AI provider (e.g., "google").
  • representation: The embedding format.
  • file_url: URL of the image to process.
    
• Headers:
  
  • Includes content type and your Eden AI API token.

‍

Interpreting the Output

Here’s an example output (simplified):

{
  "google": {
    "embeddings": [0.034, -0.238, ..., 0.712],
    "status": "success",
    "provider": "google"
  }
}

‍Explanation:

• embeddings: A high-dimensional vector representing the image.
• status: Indicates if the request succeeded.
• provider: The API provider used to generate the embeddings.
  

These vectors can now be used in image search engines, clustering models, or feature-based comparison algorithms.
