To configure the detection of lifeless faces, do the following:

  1. Go to the settings panel of the Face recognition server object, to the Analytics tab.
  2. In the Liveness detection sensitivity field, specify the sensitivity of lifeless face recognition as a percentage (see Configuring the permissions and additional settings). Default value is 50.

    Note

    To achieve more accurate lifeless face recognition, you can enable frame-based or texture-based algorithms for detecting lifeless faces or their combined operation. These algorithms can be enabled using the registry keys Va.LivenessDetectionAlgorithm and Va.LivenessTextureDetectionAlgorithm (for more information, see Registry keys reference guide; for details on working with the Windows registry, see Working with Windows OS registry).

  3. Set the Do not recognize lifeless faces checkbox to disable recognition of lifeless faces.
  4. Click the Apply button to save the settings.

Detection of lifeless faces is now configured.
