calcBackProjectAsync function

Future<Mat> calcBackProjectAsync(
  1. VecMat src,
  2. VecI32 channels,
  3. Mat hist,
  4. VecF32 ranges, {
  5. double scale = 1.0,
})

CalcBackProject calculates the back projection of a histogram.

}) async =>
    cvRunAsync(
      (callback) =>
          cffi.CalcBackProject_Async(src.ref, channels.ref, hist.ref, ranges.ref, scale, callback),
      matCompleter,
    );
