Note

Face recognition modules can operate in multi-threading mode. By default, all available processor cores are used. The number of processor cores actually used in the operation of the face recognition module is set using the CpuCoreCount registry key (see Registry keys reference guide, for details about working with the registry, see Working with Windows OS registry).

To enable the face recognition, it is necessary to activate one of the software modules:

  1. Cognitec recognition module;
  2. VisionLabs recognition module;
  3. Tevian recognition module. On the basis of the created object, it is also necessary to create an object representing the number of reference faces in the database.
  4. HUAWEI recognition module;
  5. STC recognition module;
  6. VideoIntellect 1.1 recognition module.

To activate the software module, it is necessary to create an object on the basis of the Face Recognition Server object, and name it the same as the required module.

The following objects can also be created on the basis of the Face Recognition Server object:

  1. The Archive search channel module which is used for searching the captured face in the face database and viewing the video archive of the captured face.

  2. The Face characteristics recognition channel module which is used for the facial characteristics recognition for a specified channel.

    Attention!

    The Face characteristics recognition channel module can only operate with the Tevian or VideoIntellect 1.1 face recognition module.

    Note

    If the Face characteristics recognition channel is not activated, then the facial characteristics of all newly captured faces will be marked as Undefined in the Face recognition and search interface window. However, if this module is activated later, then as Face Intellect operates and accumulates data, the undefined facial characteristics of already captured persons will be changed to averaged values.

    This module provides the recognition of the following facial characteristics:

    • Age;

      Note

      If the age of the same person is determined with poor accuracy, then it is necessary to set the 1 or 5 value for the Tevian.TrackBestFramesCount key (for details, see Registry keys reference guide, for information about working with the registry, see Working with Windows OS registry).

    • Gender;

    • Emotion;

    • Glasses;

    • Facial hair;

    • Hair color;

    • Type of bald head;

    • Headwear;

    • Artificial face;

    • Face concealment.

      Note

      If masked faces are not recognized, then it is necessary to set the 0 value for the Tevian.GlobalTrackingDetectionFilter registry key (for details, see Registry keys reference guide, for information about working with the registry, see Working with Windows OS registry).

  3. The Visitor counting channel module which is used for counting visitors and repeated passes. 

  4. The Face database replication module which is used for the Server face database replication in a distributed configuration (see Face database replication).

  5. The Recognition channel and Tevian/Cognitec/VisionLabs/HUAWEI/STC/VideoIntellect 1.1 recognition modules which are used for real-time face recognition for the specified channel.

    Note

    If it is necessary that the face recognition/non-recognition events come not from the Face recognition server object, but from the corresponding Recognition channel object, it is necessary to set the Generate a recognition event checkbox on the Recognition channel object settings panel.

Attention!

After the Visitor counting channel, Archive search channel, Recognition channel and Face characteristics recognition channel modules are activated, it is necessary to select the required Face detection object on the settings panel of the corresponding object (see Configuring the captured faces recognition parameters).
