Hello

I am new to ImageJ. I am looking to process images of 2D particles and automate particle shape analysis. I want to quantify traditional parameters e.g. below:

Where:

• ‘roundness’ is a measure of angularity and is quantified as the average radius of curvature of particle surface features relative to the radius of the maximum sphere that can be inscribed in the particle.

• ‘sphericity’ is a measure of particle ‘ellipticity’ or ‘platiness’ and is quantified as the radius ratio between the largest inscribed and the smallest circumscribing sphere.

Please could someone point me in the right direction with this?

Many thanks for your help!
