Re: [scikit-image] statistical region merging
Hi Stefanie,
Sorry, these responses should all be CCd to the list, so that others can
benefit from the discussion — my bad for dropping that thread. Could you
please:
- provide an example segmentation where skimage is doing worse than Fiji
- provide the script and parameter settings for both
Then we can help troubleshoot. I don’t know what you mean by the results
“were very strange”, for example, so it’s hard to diagnose the problem. =)
Starting to merge directly from pixels, as the Fiji plugin does, is
expensive and can be error prone. SLIC is a fast, initial pixel merging
step, from which we can merge regions according to various criteria. With
the right parameters, SLIC + RAG mean color agglomeration should give quite
similar results to Fiji’s approach…

Hi Juan,
thank you for your reply! I have seen and tested the RAG examples but I did
not understand the SLIC step and the results were very strange... Is there
any advantage? I am using SLIC anyway at the moment but the statistical
region merging of ImageJ gives me better results.
Thanks
Stefanie

Hi Stefanie!
Have a look at skimage.future.graph! There are some relevant examples in the gallery, too:
http://scikit-image.org/docs/dev/auto_examples/#segmentation-of-objects
The future.graph API is still experimental (that’s why it’s in “future”), so we really appreciate any feedback you have about it!
Juan.

Hi!
I am looking for a statistical region merging segmentation. Is there anything like this in skimage?
