Known Faces
Known faces refers to the subset of detected facial entities within a computer-vision system that have been previously enrolled, indexed, and matched against a specific database of identities. Unlike generic face detection (identifying that a face exists), known face recognition involves who the face belongs to.
Core Concepts
- Identity Enrollment: The process of capturing and encoding facial features of specific individuals into a reference database.
- Feature Matching: Comparing real-time facial embeddings against stored vectors to determine identity.
- Privacy-First Architecture: Local processing ensures biometric data does not leave the device, mitigating cloud-based surveillance risks.
Implementation Reference
A practical implementation of this concept is detailed in the following report, which demonstrates a local, free, and privacy-focused system using Python and OpenCV:
