Implementation

(VecKeyPoint, Mat) detectAndCompute(Mat src, Mat mask) {
  final desc = Mat.empty();
  final ret = calloc<cfeatures2d.VecKeyPoint>();
  cvRun(
    () => cfeatures2d.SIFT_DetectAndCompute(ptr.ref, src.ref, mask.ref, desc.ref, ret),
  );
  return (VecKeyPoint.fromPointer(ret), desc);
}
