Documentation for Face Intellect 7.4. Documentation for other versions of Intellect is available too.

Starting from Face Intellect version 7.1, the images of captured and recognized faces and vectors are stored in a folder, the path to which is specified in the FaceDB registry key. This data storage mode corresponds to the UseFaceDB = 2 mode and is set forcibly when Face Intellect starts (see Registry keys reference guide, for details about working with the registry, see Working with Windows OS registry).

Note

It is not recommended that the folder for storing face images and vectors be located on the same disk where the Intellect video archive is stored.

UseFaceDB = 2 mode provides maximum search speed and storage depth. The general algorithm of Face Intellect operation in this mode is as follows:

  • At startup, the Server reads all data from the folder into RAM. Then the received images and vectors are written to the RAM and to the folder, and the metadata is written to the database. This ensures the fastest possible search process.
  • All searches are carried out in RAM. However, this entails a high consumption of RAM and a longer start of the Server.
  • Metadata is stored in the Fir database in the Hits table. Since the images and vectors are stored in a folder on disk, the database will fill up much more slowly. This ensures maximum storage depth.

Attention!

If the UseFaceDB = 0 or UseFaceDB = 1 mode was previously used, then in order to transfer the previously accumulated data from the Face Intellect database to the folder, use the FaceRecognitionTool.exe utility (see Transferring face images and vectors when upgrading to Face Intellect 7.1 and higher).

The reference faces are stored in the <Intellect installation directory>\Bmp\<Person> folder.

Note

The reference face images from the <Intellect installation directory>\Bmp\<Person> folder can be used for automatic face verification using a script (see Examples of widely used scripts). Also, with the help of the Event Manager module, which is a part of the ACFA Intellect software, the operator controlling the Event Manager interface window can decide whether the face looking at the camera is to be verified or not. In this case, the operator compares this face with the reference face from the <Person> folder, which is displayed in the Event Manager interface window (for details about Event Manager, see Event Manager Module Settings and Operation Guide).
