Welcome to the Face Recognition Tutorial! This guide will walk you through the basics of implementing face recognition using popular libraries and frameworks. Let's dive in!

What is Face Recognition? 🤔

Face recognition is a biometric technology that identifies individuals based on their facial features. It's widely used in security systems, smartphones, and social media platforms. Here's a simple breakdown:

  • Input: An image or video frame containing a face
  • Processing: Extracting facial features (eyes, nose, mouth) and comparing them to a database
  • Output: A match or no match result

Step-by-Step Implementation 💻

1. Install Required Libraries

Start by installing the necessary packages:

pip install face-recognition

⚠️ For more details on installation, check our Face Recognition API documentation.

2. Load and Encode Faces

Use the face_recognition library to load images and encode faces:

import face_recognition

# Load known face image
known_image = face_recognition.load_image_file("known_person.jpg")
known_encoding = face_recognition.face_encodings(known_image)[0]

# Load unknown face image
unknown_image = face_recognition.load_image_file("unknown_person.jpg")
unknown_encoding = face_recognition.face_encodings(unknown_image)[0]

3. Compare Encodings

Compare the encoded faces to determine if they match:

result = face_recognition.compare_faces([known_encoding], unknown_encoding)

4. Handle Results

If result[0] is True, the faces match. Otherwise, they don't.
