sortIdxAsync function

Future<Mat> sortIdxAsync(
  1. InputArray src,
  2. int flags, {
  3. OutputArray? dst,
})

SortIdx sorts each row or each column of a matrix. Instead of reordering the elements themselves, it stores the indices of sorted elements in the output array

Implementation

Future<Mat> sortIdxAsync(InputArray src, int flags, {OutputArray? dst}) async {
  dst ??= Mat.empty();
  return cvRunAsync0(
    (callback) => ccore.cv_sortIdx(src.ref, dst!.ref, flags, callback),
    (c) {
      return c.complete(dst);
    },
  );
}
