The Tevian face recognition module operates using one of the following algorithms:

...

The fast algorythm is used by default. Use the TevianAlgorithmNumber the TevianAlgorithmNumber registry key to switch over used algorithms (see the Registry Keys Reference Guide, the current version of the document is available in the AxxonSoft documentation repository).

Vectors received by one algorithm can not be used with vectors received by another algorithm without additional processing. Conversion is requred required to use the vectors received by one algorithm with vectors received by another algorithm without repeated adding of faces to the database.    

...

Note
titleAttention!

Conversion of vectors is available if initial vectors were received in the Face - Intellect software not lower older than 5.2 version.

Vectors are converted as follows:

  1. Left click to the  icon in the Windows taskbar (system tray).
  2. In the opened window select Tools -> Recreate firs.

  3. Wait for completion of biometric vectors converting.

...

Note
titleAttention!

New vectors should be generated on the update from Face Intellect v. 7.0 to Face Intellect v. 7.1 in case the VisionLabs module is used.


Note
titleAttention!

If there are any errors in the log file while converting vectors and when the process is completed Intellect malfunctions, do the following:

  1. Shutdown Intellect.
  2. Run FaceRecognitionTool.exe tool stored at: <Intellcet installation folder>\Modules.

  3. Specify required settings - in the Path field specify the path to the folder where the data will be uploaded to (e.g. C:\Backup).

  4. Upload the data.

    titleNote

    Find more information on FaceRecognitionTool.exe in Face Recognition tool utility for extracting captured and reference faces from the database section.


  5. Execute the following script in the database manager (e.g. SQL Server Management Studio):

    Code Block
    languagesql
    USE [Fir]
GO
DECLARE	@return_value int
EXEC	@return_value = [dbo].[spReset]
SELECT	'Return Value' = @return_value
GO


  6. Start Intellect and upload images from the folder specified in the Path field to the reference face database (see Upload an image to the reference face database).
