My ImageJ knowledge is very basic at the moment, and I am trying to measure colour thresholded plant parts for my master’s thesis. I have a large amount of pictures, so I am trying to automate the process as much as possible. Each part is always in the same position on every picture. When analyzing particles, I found that objects with a curve, such as some stems, do not give an accurate width and height measurement.
Is it possible to measure the real length and width of these objects automatically and accurately? The width would ideally be measured around a cm from the right side of the object, but the width at the center of the object would also work.
