I am looking for a way to implement that QGIS Filter to smooth agriculture zones within a field. Right now I have many artifacts. I want to smooth and eliminate artifacts smaller than specified number of pixels and instead pick neighboring max.
I tried using ndimage.grey_dilation and got an acceptable result, but still have artifacts at then end (that I'd like to remove without re-running through a new dilation).
The mentioned QGIS filter seems to do something better.
Just curious. I know it is called morphological opening, but results are not awesome.
