Brandon,
Thanks so much for the quick response! I really am starting from nothing
when it comes to ImageJ. My background is in molecular biology, so I
haven't had much exposure to computer science yet. The project is sort of
a citizen science project. Participants will be all be given a grid printed
on a poster on which they will arrange the leaves before taking pictures and
sending them in. The poster will include a scale/object from which we will
set the scale.
I think I follow along with your explanation for setting the scale for a
single image in your first paragraph, but let me make sure I'm following
along with the second part. Please tell me if I am misunderstanding.
It sounds like it would be difficult to write a script that will have to
reset the scale before analyzing each new image. But, if I set it up to
take a measurement of the length of the object being used for scale and the
area of the leaf (both measurements in pixels) and outputting those values
for each individual image, then a calculation could be done for leaf area
taking into account the unique scaling factor for each image?
I think this method makes sense and I'll see if I can get it to work this
afternoon. Thanks again!
David
