I have taken SEM image of the powder particle. It contains different size of the particle. I wanted to measure the particles varying in a size from 15 to 60 micron. How can I do it automatically using the MATLAB codes and I wanted to leave the particles which are less than 15 micron and greater than 60 micron. In SEM image there are some irregular shapes which also needs to be left while measuring the particle size. Can someone please help me with it.

I have 3 comments:
- Removing parts of the particle size distribution (< 15 microns; > 60 microns; irregular particles) provides you little or no information and does not generate a (correct) particle size distribution based on length or mass. You need to work out how you wish to deal with the irregular particles that make up a good proportion of the mass (and hence value) of the system. See attached
- Your picture is far too dense with overlapping particles making it close to impossible to separate distinct particles from touching or agglomerated particles. The particles need to be discrete and separated for accurate 'measurement'. You need a lower concentration on the slide
- A picture is a 2D representation of a 3D system and particles are 3D entities. We have no idea of the z-axis of any particle shown
I fully agree with Alan F Rawle : you should first work on your sample preparation in order to get better separated particles and remove overlapping.
Not that your picture cannot be processed using Matlab or ImageJ or any other IA software, but it would make your algorithmics much easier...
There is only one software that you can manually measure the various particle size in your image. As Pierre mentioned, MATLAB and ImageJ can not be applicable to your image due to the irregular shape and distribution.
