connectedComponentsAsync function

Future<int> connectedComponentsAsync(
  1. Mat image,
  2. OutputArray labels,
  3. int connectivity,
  4. int ltype,
  5. int ccltype,
)

ConnectedComponents computes the connected components labeled image of boolean image.

Implementation

Future<int> connectedComponentsAsync(
  Mat image,
  OutputArray labels,
  int connectivity,
  int ltype,
  int ccltype,
) {
  final p = calloc<ffi.Int>();
  return cvRunAsync0(
    (callback) =>
        cimgproc.cv_connectedComponents(image.ref, labels.ref, connectivity, ltype, ccltype, p, callback),
    (c) {
      final rval = p.value;
      calloc.free(p);
      return c.complete(rval);
    },
  );
}
