void setTrackerMatchingThreshold(

1. int trackerMatchingThreshold

)

Sets the minimum match score to reach to preserve the ID of a tracked face between frame 't-1' and frame 't'. Hint: Default value is 3000 which corresponds to a False Match Rate of 1/1000.

param trackerMatchingThreshold Minimum match score to reach to preserve the ID of a tracked face between frame 't-1' and frame 't'. throws FaceException An error has occurred during Face Library execution.

## Implementation

    void setTrackerMatchingThreshold(int trackerMatchingThreshold) {
      var err = faceSDK.id3FacePortraitProcessor_SetTrackerMatchingThreshold(_pHandle.value, trackerMatchingThreshold);
      if (err != FaceError.success.value) {
        throw FaceException(err);
      }
    }
