# getFaceDetectionThreshold method

int getFaceDetectionThreshold()

Gets the specifies the face detection confidence threshold, in the range is (0;100). Hint: Default value is 50. Setting a high threshold reduces false detections but may increase the number of undetected faces.

return Specifies the face detection confidence threshold, in the range is (0;100). throws FaceException An error has occurred during Face Library execution.

## Implementation

    int getFaceDetectionThreshold() {
      Pointer<Int> pFaceDetectionThreshold = calloc();
      try {
        var err = faceSDK.id3FacePortraitProcessor_GetFaceDetectionThreshold(_pHandle.value, pFaceDetectionThreshold);
        if (err != FaceError.success.value) {
          throw FaceException(err);
        }
        final vFaceDetectionThreshold = pFaceDetectionThreshold.value;
        return vFaceDetectionThreshold;
      } finally {
        calloc.free(pFaceDetectionThreshold);
      }
    }
