Re: Water-shedding non-circular particles
Also Juan, When you say, "There have been some recent developments on that function," are you referring to the peak_local_max() function? On Thursday, March 19, 2015 at 6:07:58 PM UTC-4, Claiborne Morton wrote:
Hey guys, Im still having trouble finding ways to separate touching particles if the are not both circular. Further when dealing with elliptical shapes, a single particle tends to incorrectly get cut in half. Any ideas how I could change parameters in the water-shedding function to correct for this? Attached are a few problem cases so you can see examples.

Yes, that's what I mean. I haven't used it so I can't offer guidance there but you might want to fiddle with the parameters / update your scikit-image to the github master version. Regarding your source images, it looks like there is a nice signal separating touching cells. You might want to run an edge detector (e.g. Ilastik) or even just morphologically opening your images prior to thresholding. Juan.
