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

  1. Fast and less resourceintensive less resource-intensive algorithm.
  2. Slow and more resourceintensive resource-intensive algorithm providing the higher quality of recognition for large samples.

The fast algorythm is used on 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).

Biometric vectors Vectors received by one algorithm can 't not be used with vectors received by another algorithm without additional processing. It's required to convert biometric vectors Conversion is required to use biometric the vectors received by one algorithm with vectors received by another algorithm without repeated adding of faces to the database.    

Converting Conversion of biometric vectors also allows enables using of vectors the  vectors received by another recognition module, e.g. Cognitec, while its changing to if it is replaced by the Tevian recognition module.

Note
titleAttention!

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

Biometric vectors 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.

Vectors are now converted.

...

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.

    Info
    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).
