Pore Network Coordination Number of 2D porous media images using watershed
segmentation algorithm
Coordination number is also called pore connectivity and shows that each
pore is connected to what number of adjacent pores
This parameter is key to find the relationship between porosity and
the permeability of porous media

You will need the image processing license to run this code
