I have 5 sets of coated samples and my intention is to determine the average pore size of the coating for each of them. The sample under examination is a IJP coating of YSZ material on porous alumina. SEM images appear to show small pits(which are not pores) and open pores. I have tried image analysis using imageJ to get an average pore size figure, but thresholding of image did not give accurate results.

Is there a software which could be used to directly take out an average pore size value. If not, are there any other methods?

Any help/suggestion is much appreciated.

Thanks in advance.

Rahul.
