Keep in mind that however smooth it will look the zigzag thing is just
the reality and defines what you will measure.
I see two possibilities to make it look smoother:
1. scale up the image with the interpolation option selected (Image>Scale)
2. Have a look at the ObjectJ plugin (http://simon.bio.uva.nl/objectj/).
I think it can do what you want, but I'm not sure. Maybe someone else
can confirm this?
