General information on stored face types and related data

The face recognition server stores three types of face images:

• Reference faces are face images compared with images of faces fixed on a video image.
  Reference faces database is filled manually in the Face recognition and search interface object (see Adding images to the reference face database).
• Captured faces are face images recorded on a video image.
  Photos of captured faces can be viewed in the Face recognition and search interface object (see Configuring the Face recognition and search interface object).
• Recognized faces are captured faces who have shown a sufficient degree of similarity to the reference faces.
  Photos of recognized faces can be viewed in the Face recognition and search interface object (see Configuring the Face recognition and search interface object).

In addition, during the recognition process, the following data is created and stored:

• Vector is the mathematical representation of the face, created when it is recognized in the frame of the video image.
• Metadata is the data that enables linking the reference, captured and recognized faces to each other, for example, their identifiers.
