Hi,
I'm wondering if there is anyone who has advice on using image J to measure
area. We have just purchase a scion image grabber but using our own camera,
and cant seem to calibrate the programme to measure area accurately. I can
get it to measure accurately in a straight line but not to measure area
properly, which is unfortunate as thatÂ’s the reason we have it! The only
reason I can see that it would not measure a square as even on all sides to
give an accurate area is that the pixel scale is different horizontally
from vertically. I cant see any evidence of this though or any option to
change this if it is so.
Kind Regards,
Tracey Jones
