To extract load captured or reference faces from the database, do the following:

1. Click the Get all servers button to display all the  available face recognition servers (1).
   
2. In the Servers: field set the checkboxes next to the face recognition servers that will supply the data (2).
3. Specify the date and time of the start and the end of time interval for which data is to be extracted loaded (3).
4. In the Mode: drop-down list select the extracted loaded data type:
   1. Protocols – extract load the faces captured by the Face Recognition Server.
   2. Protocols with engine info – extract  – load the faces captured by a Face Recognition Server adding the name of recognition module in the end of each file.
   3. Big filesystem – extract load a large amount of data from the database. In this case data will be extracted loaded according to special algorithm.
   4. Persons – extract load the reference faces added to the Face Recognition Server database.
5. Specify a path to the folder to which the data will be extracted loaded in the Path field (5).

6. Click the Run button to

   extract

   load the data to the folder (6). The total number of faces

   extracted

   Two files will be

   extracted

   loaded for each captured face – the corresponding vector in .bin format and the  image of the detected face in .jpg format. The name of each file has the following structure: [date and time] - [ID] - [recognition module].

   The faces added to the Face Recognition Server database are loaded to the Path: folder. For each .jpg file with an image of a captured face, a .json file with the same name will be placed in the same folder. The .json file contains the user's full name, department, comment and other data that are taken into account while loading images from the folder to the face database (see Face Intellect Operator's Guide, the

   Load

   Upload an image to the reference face database section).

   Info
   title Note
   If there are forbidden characters (\/:*?"<>|) in the name of the reference face file added to the Face Recognition Server database, then these characters will be replaced with _ character.
