The face database replication is used in a distributed configuration with several Servers, so that when new faces are added to the face database of the main Server, the same faces are automatically added to the face database of other Servers in the distributed configuration. Also, when the face database replication is activated, the changes on the main Server of such data as photo, name, last name or comment are also synchronized with other Servers. Any server in a distributed configuration can act as the main server. You can configure it in such a way that the Server that receives the face data from the main Server is itself the main Server for any other Servers.

Note

  • The face database is synchronized in the background every 10 seconds.
  • Due to the fact that the Servers in a distributed configuration are set up differently, some photos of faces from the main Server may not be added to other Servers. To save such photos to a folder on the main Server, it is necessary to change the value of the LogBadImages parameter to True (see XML-file parameters reference guide).

For the Face database replication module activation, see Activation of the recognition modules in Face Intellect. To configure the face database replication, do the following:

  1. Go to the settings panel of the Face database replication object.
  2. In the Replication sources list (1), set the checkboxes for those Face Recognition Servers that will be considered main ones

  3. Using the higher or lower buttons (2), set the priority of the Servers. The top position in the list indicates the highest priority. The face database is replicated only from one of the most priority available Servers.

    Note

    For example, there are three Face Recognition Servers in a distributed configuration: C1, C2 and C3. The face database replication is configured on C1. C2 has a higher priority than C3. In this case, if C2 is available, then when adding faces to C2, the same faces will automatically be added to C1. The face database will be replicated from C3 to C1 only if C2 becomes unavailable.

  4. Set the Delete faces from local database checkbox (3) to allow the addition and deletion of faces from the face database of the local Server.

    Note

    If this checkbox is not set, then when adding a face to the local Server database, it will be automatically deleted, but if you delete a synchronized face, it will be added again after 10 seconds. In this case, to completely remove a face from the local Server, it is necessary to rename it first.

  5. Click Apply (4) to save the settings.

The face database replication is configured.
