G’Day Everyone

I am using the Analyze Particles feature to analyse porosity in Aluminium. I’d like to accurately calculate the shape of the pores, which requires the particle perimeter to be calculated. I also am measuring other characteristics (area, location), so I am currently Analyse Particles plugin.

I’ve noticed that the typical border pixel count of Perimeter that is given by the Analyse particles Feature isn’t accurate enough for my needs. For example, using the typical pixel border count method, for a perfect cicle I get a circularity of 0.89… I’d like to calculate the crofton perimeter of the particles, to increase the accuracy of my measurements.

Does anyone know how I could incorporate the Crofton Perimeter into the analyze particles measurement? Is there someway to customize the measurements??

Cheers,

Julian
