Steve – since I don’t know Mathworks’ information flow, I just wanted to be sure to use every communication channel :-)

Best regards, Wolfgang

Wolfgang—I was notified when your enhancement request came in because you mentioned my name. ;-) I read up on the algorithm in Soille’s book on image morphology, and I agree that it seems promising.

Hi Steve,

I always thought that plateau processing could not be handled by the “standard” image processing techniques available. Now I came across some work done by Pierre Soille, who address exactly the problem of plateau processing using geodetic distance transforms. Geodetic distance transforms are extremely interesting and I already made an enhancement request to include it as add-on to the morphological reconstruction library of the IPT. Besides plateau processing, geodetic distance transforms are useful for various other applications like
- Interpolation in images
- minimal path detection in images
- morphological image segmentation
- simplified modelling of physical processes in discrete heterogeneous media such as fluid penetration in porous media

It would be nice, if you could agitate for including such functionality in future versions of the IPT.

Best regards,
Wolfgang

Urs—Yep. I hated that old picture. :-)

an all-new mug-shot – ready for image processing…
