> Oggetto: use of imageJ for herbivory assessment
>
> Hello all,
> I'm attempting to use ImageJ to analyze scanned images of leaves in
> order to assess percentage of leaf area lost to herbivory. In so
> doing, I've encountered two problems already (and I've just started):
> 1) The "wand" tool, selected from the toolbar, will, at most outline
> only one hole per leaf, will not outline the leaf perimeter, and, more
> generally, is often completely non-responsive; and 2) in trying to use
> a mouse or trackpoint to control the "freehand" tool from the toolbar
> to outline the leaf perimeter (or reconstruct an eaten leaf perimeter),
> my hand clearly is not steady enough to closely follow the path that I
> desire. I would greatly appreciate it if anyone would suggest
> either alternatives to these 2 tools, or ways that I can use them more
> effectively. Also, if you know of a standard protocol for herbivory
> assessment that's compatible with the current version of ImageJ, that
> would probably solve all of my problems.
> Thanks very much,
