distanceTransform function

(Mat, Mat) distanceTransform(
  1. Mat src,
  2. int distanceType,
  3. int maskSize,
  4. int labelType, {
  5. Mat? dst,
  6. Mat? labels,
})

DistanceTransform Calculates the distance to the closest zero pixel for each pixel of the source image.

distanceType: DistanceTypes maskSize: DistanceTransformMasks labelType: DistanceTransformLabelTypes

Implementation

(Mat dst, Mat labels) distanceTransform(
  Mat src,
  int distanceType,
  int maskSize,
  int labelType, {
  Mat? dst,
  Mat? labels,
}) {
  dst ??= Mat.empty();
  labels ??= Mat.empty();
  cvRun(() => cffi.DistanceTransform(src.ref, dst!.ref, labels!.ref, distanceType, maskSize, labelType));
  return (dst, labels);
}
