title: What is the difference between Face Detection and Face Recognition in iOS perspective
body: <p>May be this sounds like a stupid one, but i really curious to know that, what is the difference between "Face Detection and Face Recognition" in iOS perspective? And in what case or which kind of situation should i use the two of them. I am new in iOS and have never any previous tinkle down experience about iOS face Detection/Recognition related thing. I am going to make an application, where i have to detect user face (by camera, not after taken photo) with database picture collection. Please give you response if any, and please don't misunderstand my question. O:)</p>
  
  <p>-Thanks a lot in advanced.</p>
