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

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

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

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

Converting of biometric vectors also allows using of vectors received by another recognition module, e.g. Cognitec, while its changing to the Tevian recognition module.

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

Biometric 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.

  4. New biometric 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.

Biometric vectors are now converted.
