openCV нет подходящей функции fillPoly

Я пытаюсь реализовать этот ответ, но я получаю всегда ошибку. Пожалуйста помоги.

Мой код:

cv::Point corners[1][6];

for (unsigned long j = startIndex; j < startIndex+6; j++) {
int x = shape.part(j).x();
int y = shape.part(j).y();

corners[0][j-startIndex] = Point(x, y);
}
const Point* corner_list[1] = {corners[0]};

cv::Mat mask(image.rows, image.cols, CV_8UC2);
cv::fillPoly(mask, corner_list, 6, 1, cv::Scalar(255), 8);
cv::Mat result(image.size(), image.type(), cv::Scalar(0,0,0));
image.copyTo(result, mask);

Вот моя ошибка:

jni/jni_detections/jni_face_det.cpp:121:5: error: no matching function for call to 'fillPoly'
cv::fillPoly( mask, corner_list, num_points, num_polygons, cv::Scalar( 255, 255, 255 ),  line_type);
