Does FME have an equivalent of mdenoise?

Mdenoise is an denoising algorithm for topographic use that preserves sharp edges. It's part of GDAL, so I was wondering if it maybe was integrated in FME, but under another name? Or is there an transformer that works in a similar way?

 

Some background to mdenoise:

@aron​ You could try TINGenerator with breaklines (if you have them) or the PointCloudSimplifier . Or you can run the mdenoise exe using the SystemCaller as you can do in GRASS GIS.

I don't think mdenoise is a GDAL applicaiton. They are just suggesting using GDAL to convert any DEMs you have to the support grid format - Esri ASCII GRID. which FME can do of course.
