Face recognition is the ability to recognize faces. Sometimes our brain tends to see faces in alot of things. An interesting psychological phenomenon called "Pareidolia". The brain can see/find faces in anything. Pareidolia is perceiving a vague stimulus (a tree,cloud) as specific one (a face, a person, a word, etc).
