findContours function

(Contours, VecVec4i) findContours(
  1. Mat src,
  2. int mode,
  3. int method
)

FindContours finds contours in a binary image.

Implementation

(Contours contours, VecVec4i hierarchy) findContours(Mat src, int mode, int method) {
  final hierarchy = VecVec4i();
  final contours = VecVecPoint();
  cvRun(() => cimgproc.cv_findContours(src.ref, contours.ptr, hierarchy.ptr, mode, method, ffi.nullptr));
  return (contours, hierarchy);
}
