HoughLinesAsync function

Future<Mat> HoughLinesAsync(InputArray image, double rho, double theta, int threshold, { OutputArray? lines, double srn = 0, double stn = 0, double min_theta = 0, double max_theta = CV_PI, })

HoughLines implements the standard or standard multi-scale Hough transform algorithm for line detection. For a good explanation of Hough transform, see: http:///homepages.inf.ed.ac.uk/rbf/HIPR2/hough.htm

Implementation

  double rho,
  double theta,
  int threshold, {
  OutputArray? lines,
  double srn = 0,
  double stn = 0,
  double min_theta = 0,
  double max_theta = CV_PI,
}) {
  lines ??= Mat.empty();
  return cvRunAsync0(
    (callback) => cimgproc.cv_HoughLines(
      image.ref,
      lines!.ref,
      rho,
      theta,
      threshold,
      srn,
      stn,
      min_theta,
      max_theta,
      callback,
    ),
    (c) {
      return c.complete(lines);
    },
