Face recognition software created with the help of artificial intelligence utilizes advanced algorithms to detect, analyze, and recognize human faces within video frames or digital images by extracting discriminative facial features and creating mathematical representations known as facial signatures. Face recognition systems typically operate through a series of steps: face detection, feature extraction, face alignment, and matching against a database to recognize or authenticate. Some salient features include real-time detection, high accuracy levels, anti-spoofing, and multi-face support. Recent solutions employ deep learning and neural networks to improve the speed and precision, with applications in security, access control, digital onboarding, and customized user experiences in various industries.
