# getTrackerMatchingThreshold method

int getTrackerMatchingThreshold()

Gets 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.

return 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

    int getTrackerMatchingThreshold() {
      Pointer<Int> pTrackerMatchingThreshold = calloc();
      try {
        var err = faceSDK.id3FacePortraitProcessor_GetTrackerMatchingThreshold(_pHandle.value, pTrackerMatchingThreshold);
        if (err != FaceError.success.value) {
          throw FaceException(err);
        }
        final vTrackerMatchingThreshold = pTrackerMatchingThreshold.value;
        return vTrackerMatchingThreshold;
      } finally {
        calloc.free(pTrackerMatchingThreshold);
      }
    }
