# Introduction

Face Detection detects faces and returns their location.

Face Recognition identifies people by comparing detected faces to faces in your training database.

After detecting faces, Media Server can also:

- estimate demographic information such as age, gender, and ethnicity.
- report information such as the facial expression, whether the person's eyes are open or closed, and whether the person is wearing spectacles.

NOTE: Media Server can analyze faces for demographics and facial expression only when the person is looking directly at the camera.

You can run face detection and face analysis operations out-of-the-box. To run face recognition, you must train Media Server using images of people that you want to identify. For information about how to train Media Server, see Train Face Recognition.
