Dear users, I am working with the watershed algorithm to mark grains and I am wondering what exactly is meant by the parameter drop size in percentage. I interpreted this in that way that a drop with a size of 0.1% has a size of 0.001µm² in a 1µm² picture. Is that right?
If so, in a 1µm² picture with 512x512 pixels this drop would have a size of approximately 272 px², so that the smallest lake/grain marked in the end should be bigger or equal to 272px², shouldn't it? But I get a lot of marked grains smaller than this size in my picture (e.g. I can erase a lot of drops via a surface threshold of lets say 60px²). Which mistake did I make in my thoughts? Or is percentage of a volume meant and if so what scale is taken as the "height" of the volume? One more question apart from that came into my mind: Can a drop go into a minimum that is smaller than the size of the drop? I.e. is the drop "really" a fluid and can change its shape? Unfortunately I did not find information about this on the Gwyddion web pages. I would be very thankful for any help.
