I haven't found such a filter, too. I use BinaryDilate and BinaryErode
to apply closing to a binary image. But why are you thinking that this
hasn't the same effect? Closing is just a dilation followed by am
erosion and opening is just an erosion followed by a dilation. If
BinaryErode and BinaryDilate work correctly - and I think we can
assume this - the combined execution should lead to the right results.
