Hi, I’ve searched (basically, _googled_ it) but could not find one, thought I’m convinced that id does exist. Anyone knows how to do what Matlab’s [bwareaopen](https://www.mathworks.com/help/images/ref/bwareaopen.html) does?

Thanks.

That looks really similar to the `remove_small_objects` function in SciKit-Image that I’ve used for doing watershed segmentation. Maybe ImageSegmentation.jl will have a similar function?

You can use the functions from ImageMorphology and here especially the `area_opening` function

Thanks, that’s indeed what I was looking for.
