Learning
Memory Aids

FACE RECOGNITION = FACE (what you see) + RE-COGNITION (knowing again). Think of your phone 'knowing your face again' to unlock.
Conceptual Metaphor
THE FACE IS A PASSWORD; THE CAMERA IS AN EYE THAT REMEMBERS.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'распознавание лица' if context is human cognitive ability; use 'узнавание лиц' instead. For technology, 'распознавание лиц' is correct.
- Do not confuse with 'face detection' ('обнаружение лиц'), which finds faces but does not identify them.
Common Mistakes
- Using 'face recognition' as a verb (e.g., 'The system will face recognition you'). Correct: 'The system will use face recognition on you' or '... will perform face recognition'.
- Confusing 'face recognition' (identity) with 'face detection' (presence).
- Incorrect hyphenation: 'face-recognition' is less common than the open or spaced compound.

FAQ
Frequently Asked Questions
Yes, they are virtually synonymous in modern usage, though 'facial recognition' is slightly more formal and common in technical writing.
Yes, in psychology and neuroscience, it refers to the human cognitive process of identifying familiar faces. In most contemporary contexts, however, it refers to technology.
The primary concern is privacy, as it enables persistent identification and tracking of individuals in public spaces without their consent, potentially leading to mass surveillance.
Face detection simply finds and locates human faces in an image or video. Face recognition goes a step further to identify whose face it is by matching it against a known database.
