I was wondering if someone could point me in the right direction regarding the following. I am studying abrasive particles and have many SEM still images of particles ranging from 10-120 microns. I am looking for some software that will allow me to easily calculate various properties relating to the particle, such as size, geometry, area ect - or anything really that might be of use to allow me to compare one particle with another.
1) Is there certain features which may be useful to know when it comes to comparing abrasive particles?
2) Is there simple software available that would be suitable (i was recommended a program called SIGMAscan but this seems perhaps too much of an investment at around $900 for what i need it for).
