Q:

Image Segmentation, watershed, waterfall, p algorithm

I was wondering if anyone is aware of any currently available packages for segmentation using the waterfall method or p algorithm. I've looked in github, CRAN, and Fiji and haven't found anything despite published literature discussing the benefits of waterfall and the P algorithm methods going back to 2009. Right now I'm using watershed segmentation on some images but keep running into problems with oversegmentation and it seems like these other two methods might solve some of these issues.
Edit: Here are some of the papers I was referencing:

Serge Beucher: "Watershed, Hierarchical Segmentation and Waterfall Algorithm" (Springer, fee required)
BEUCHER, MARCOTEGUI: P algorithm, a dramatic enhancement of the waterfall transformation

A:

For the sake of completeness, an answer regarding the Hierarchical segmentation was posted on the ImageJ mailing list by Ignacio Arganda-Carreras. He implemented it on an experimental branch of MorphoLibJ.
All credits go to Ignacio!
