How Facial Recognition
Works with Machine

Introduction to Facial Recognition
Facial recognition is a technology that identifies or verifies a
person using their facial features.‌
It is widely used in security, authentication, and social media
applications.‌
Modern systems rely heavily on machine learning to improve‌
‌accuracy.‌
iabac.org‌

Face Detection: ‌Locate a face in an image or video.
Feature Extraction: ‌Identify unique facial landmarks (eyes, nose,‌
‌mouth, contours).‌
Face Representation: ‌Convert facial features into a numerical‌
‌format (feature vectors).‌
Matching & Recognition: ‌Compare feature vectors against a
database for identification or verification.‌
Key Steps in Facial Recognition

Role of Machine Learning
Machine learning models, particularly deep learning and convolutional
neural networks (CNNs), analyze facial patterns.‌
The system learns from large datasets of labeled faces to recognize
variations in lighting, angles, and expressions.‌
Continuous training improves accuracy and reduces false matches.‌

Smartphone unlock and identity verification‌
Attendance tracking and personalized experiences‌
Applications
Challenges
Privacy concerns and data security‌
Bias in datasets leading to accuracy disparities‌
