To set configure the recognition parameters for the of captured faces recognition, do the following:

1. Go to the settings panel of the Face recognition server object on the General settings tab (1).
   
2. Set the Select the best frame for recognition checkbox (2) to select the best frame from all images of one person which that came from the Face detection tool to the the Face recognition server and create FIR only for it.
3. In the Similarity level field (3), enter specify the similarity level of between the captured face and the reference image as a percentage, above which the face is considered recognized. The Similarity level parameter is specified in percent.

4. In the Search for similar faces field (4), enter specify the maximum number of similar reference images, which identifiers and similarity level will be stored in database for one frame of a captured face.

   Info
   title Note
   It is recommended to specify We recommend specifying the 1 value for this field for a more precise search of the recognized faces (see see Filtering the recognized and unrecognized faces).

   
   

5. In the Minimum quality for face recognition (0-100) field (5), enter specify the minimum quality of the captured face in percent, at which the recognition should be performedit is recognized. The default value is 60% 60%.
   

   Note
   title Attention!
   If recognition of face concealment recognition is enabled, then in order to correctly detect the presence of a face mask, it may can be necessary to set the the Minimum quality for face recognition (0-100) value below the default value (see Configuring the permissions and additional settings).

   
   

6. In the Minimum quality for adding face to DB (0-100) field (6), enter in percent specify the minimum quality of face to be added to the database as a percentage. 

7. Set the Create FIR in detection unit checkbox (7), so that the face detection tool generates and attaches biometric parameters to the face image. If the checkbox is clear, the detection tool will only capture captures faces, and the Face recognition server will generate generates and attach attaches the biometric parameters. 
8. Set the Select the best frame in detection unit checkbox (8), so that only the best frame is sent to the Face recognition server. If the checkbox is clear, all frames will be are sent to the Face recognition server.

9. In the Skip repeated recognitions, s field (9), set the time period in seconds during which a captured face wonisn't be recognized repeatedly. The default value is 2. See also the IgnoreSamePeople registry key .

   in the Registry keys reference guide, for details about working with the registry, see Working with Windows OS registry.

10. Set the Use GPU checkbox (10) to select the discrete graphics card when using the VA and VideoIntellect 1.1 face recognition modules. If the checkbox is clear, the the recognition will be is performed on the CPU. 

    Note
    title Attention!
    If the Use GPU checkbox is set for the first time, then at the same moment the caching process will start starts in a new window to optimize the recognition on the current GPU. Do not interrupt this process. If for some reason the caching process was interrupted, it is necessary to delete the folder with the name "GPU-[video card UUID]" at <Face PSIM installation directory>\ Modules64\Firserver\FaceRecognition\Va_ [SDK version]\ (for the VA module). Afterwards, when the Use GPU checkbox is set, the recognition using the GPU will be is performed immediately without the caching process. If you replace the video card, the caching process will restart automaticallyrestarts automatically. After the caching process is complete, enable the recognition using the GPU by selecting the video card from the Select GPU drop-down list in the settings of the Face Detection object (see Basic settings of the Face Detection module).

    
    

11. In the Collected no less than ... frames with person field (12), enter specify the minimum number of frames to be collected for the face to be after which a face is recognized.

12. In the Person in field of view no less than … seconds field (13), enter specify the time in seconds upon reaching which the recognition will startstarts.

    Note

    Info
    title Note
    title	The Person left the camera field of view condition is always enabled (11).
    Info
    The face recognition starts if at least one of the three conditions (11-13) is met.
