filter2D function

Mat filter2D(
  1. InputArray src,
  2. int ddepth,
  3. InputArray kernel, {
  4. OutputArray? dst,
  5. Point? anchor,
  6. double delta = 0,
  7. int borderType = BORDER_DEFAULT,
})

Filter2D applies an arbitrary linear filter to an image.

Implementation

Mat filter2D(
  InputArray src,
  int ddepth,
  InputArray kernel, {
  OutputArray? dst,
  Point? anchor,
  double delta = 0,
  int borderType = BORDER_DEFAULT,
}) {
  dst ??= Mat.empty();
  anchor ??= Point(-1, -1);
  cvRun(
    () => cimgproc.cv_filter2D(
      src.ref,
      dst!.ref,
      ddepth,
      kernel.ref,
      anchor!.ref,
      delta,
      borderType,
      ffi.nullptr,
    ),
  );
  return dst;
}
