I ve been using ImageJ now for months and it has been quite reliable for my puposes. There are still some Feature I could not figure out though they seem very simple to me.
For example I have to find out “bottlenecks” in selected structures in an Image, i.e. the smallest distance within a selection. Imagine imagej being used to measure the mimimum and the maximum widths of streets. The wand tool gives a very simple way to select structures like streets. But how do get the most narrow distance? And is there a way to get imagej not only to show the value but also to mark theses places on the Image?
Thanks for your support.
