laplacian function

Mat laplacian(
  1. Mat src,
  2. int ddepth, {
  3. Mat? dst,
  4. int ksize = 1,
  5. double scale = 1,
  6. double delta = 0,
  7. int borderType = BORDER_DEFAULT,
})

Laplacian calculates the Laplacian of an image.

Implementation

Mat laplacian(
  Mat src,
  int ddepth, {
  Mat? dst,
  int ksize = 1,
  double scale = 1,
  double delta = 0,
  int borderType = BORDER_DEFAULT,
}) {
  dst ??= Mat.empty();
  cvRun(() => cimgproc.cv_Laplacian(src.ref, dst!.ref, ddepth, ksize, scale, delta, borderType, ffi.nullptr));
  return dst;
}
