[Feature request] Hit and Miss Transform

[aquatiko]

I was studying about some morphological operations and came across Hit and Miss Transform method. I was unable to find an implementation in Julia. Does this need to be implemented or is it implemented elsewhere. Also, If a need is there, where would be a suitable place to add it?

Thank you! Do you have a reference that you could share about the transforms ?

Thanks for sharing! I am guessing that we have something already implemented in Images.jl that covers the hit-miss transform? Would it be correct to say that the filtering operations in ImageFiltering.jl cover this use case of foreground and background elements in the structuring element?

Also the related packages outside of the Images.jl organization may be of your interest as well: https://github.com/JeffreySarnoff/RollingFunctions.jl and https://github.com/emmt/LocalFilters.jl

What exactly is the API you have in mind? A more general way to define the structuring element? Generalizations are always very welcome :)
