How Facial Recognition Systems Work: Detection, Comparison, and Recognition Explained

Facial recognition systems have rapidly evolved, impacting various industries from security to consumer applications.

Eden AI offers a robust facial technology system that integrates multiple AI providers, allowing users to perform facial detection, comparison, and recognition efficiently.

This guide explores how this technology works, the differences between detection, comparison, and recognition, and its real-world applications.

Watch our video on facial recognition systems to have an in-depth overview on the subject and see how developers can integrate these features using Eden AI's API:

Understanding Facial Recognition Systems on Eden AI

Eden AI simplifies access to multiple AI-powered facial recognition models, enabling businesses and developers to integrate facial recognition capabilities without being locked into a single provider.

The three primary functions—detection, comparison, and recognition—each serve distinct purposes:

‍

1. Face Detection

Face detection identifies whether a face is present in an image or video. Unlike recognition, it does not determine identity but locates facial features, which is essential for applications such as:

• Security and surveillance – Detecting unauthorized individuals in restricted areas.
• Smart cameras and devices – Enabling automatic adjustments based on detected faces.
• Content moderation – Detecting inappropriate content that contains faces.

Eden AI provides access to various detection models, ensuring optimal performance across different use cases. The video illustrates how Eden AI's API can be used to detect faces in real-time, showing different detection scenarios and their respective results. Here is a quick overview of how it works on Eden AI:

‍

How to Use Face Detection on Eden AI:

1. Access the API: Sign up on Eden AI and obtain an API key.
2. Send a Request: Use the provided endpoint to upload an image. You can watch our tutorial for an example.
3. Receive a Response: The API returns bounding box coordinates for detected faces.
4. Implement in Applications: Use the data to highlight faces in images or videos.

‍

2. Face Comparison

Face comparison measures the similarity between two faces, determining whether they belong to the same individual. This is useful for:

• Identity verification – Comparing a user’s selfie with an official ID photo.
• Access control – Granting or denying entry based on face matching.
• Fraud prevention – Detecting attempts to impersonate another individual.

Eden AI’s system analyzes facial features and provides similarity scores, allowing users to implement tailored security measures. The YouTube video walks through an example of comparing two images and interpreting the confidence score returned by different AI providers integrated within Eden AI.

‍

How to Use Face Comparison on Eden AI:

1. Upload Two Images: Provide two image URLs or file uploads.
2. Send a Request: Watch our tutorial for an example API request.
3. Receive Similarity Score: The API returns a similarity percentage.‍
4. Apply the Results: Set a threshold to determine if two faces match (e.g., 85% similarity for identity verification).

‍

3. Face Recognition

Face recognition goes beyond comparison by identifying individuals based on a stored database. This is widely used for:

• Workplace security – Granting employee access to restricted zones.
• Customer personalization – Recognizing VIP clients in retail environments.
• Forensic investigations – Identifying suspects from surveillance footage.

Eden AI aggregates multiple recognition models, ensuring flexibility and accuracy in diverse environments. The video demonstrates how developers can use Eden AI’s API to run face recognition and explains how to optimize accuracy by selecting different AI models.

‍

How to Use Face Recognition on Eden AI:

1. Create a Face Database: Upload known face images to the Eden AI system.
2. Register Faces: Associate each face with an identity label.
3. Send a Recognition Request: Watch our tutorial for an example.
4. Receive Identification Results: The API returns the closest matches from the database.‍
5. Implement for Security or Personalization: Use the recognized identity for login systems, access control, or personalized recommendations.
