What is Face Comparison?

Face comparison is a powerful feature used in security, identity verification, and facial recognition systems. It allows users to determine the similarity between two facial images, which is crucial in applications like access control, user authentication, and forensic investigations.

This technology plays a key role in ensuring only authorized access, verifying identities quickly, and helping law enforcement match faces in criminal investigations.

Eden AI provides an efficient and accessible solution for face comparison by integrating multiple AI providers through a single API.

Live Test Models on Eden AI

Eden AI provides an interface where you can test different AI models before integrating them into your application. This allows you to evaluate which provider best meets your needs.

‍

Install JavaScript's Requests Module

To interact with APIs in JavaScript, you can use Axios, a popular HTTP client library. If you don’t have Axios installed, you can install it via npm:

  npm install axios

‍

Prepare the Code

Below is the JavaScript code to interact with the Eden AI API for face comparison:

const axios = require("axios").default;

const options = {
  method: "POST",
  url: "https://api.edenai.run/v2/image/face_compare",
  headers: {
    Authorization: "Bearer YOUR_API_KEY",
  },
  data: {
    providers: "base64",
    file1_url: "🔗 URL of your reference image",
    file2_url: "🔗 URL of your query image",
  },
};

axios
  .request(options)
  .then((response) => {
    console.log(response.data);
  })
  .catch((error) => {
    console.error(error);
  });

API Authentication:

• The Authorization header contains your API key, which authenticates the request.
  

JSON Payload:

• providers: Defines the AI providers to use for face comparison (in this example, base64).
• file1_url: The URL of the reference image.
• file2_url: The URL of the image to be compared.
  

Sending the Request:

• The axios.request(options) sends a POST request to Eden AI’s face comparison endpoint. The request includes the provided images and selected AI provider.
  

Handling the Response:

• If the request is successful, the response will be logged with console.log(response.data).
• If there’s an error, it will be caught and logged using console.error(error).

Interpreting the Results

Example Output

  
{
  "facepp": {
    "similarity": 89.5,
    "confidence": 92.3,
    "status": "success"
  }
}
  

• similarity: This field indicates the percentage of similarity between the two faces. A value of 100% means an exact match.
• confidence: Represents the confidence level of the AI model’s prediction.
• status: Indicates whether the comparison process was successful.
