How to Identify Pore-Geophysical parameters of 2D_Thinsection_Sandstone Image by Image Processing
I want to measure the 2D image geophysical parameters (Porosity, Pore Diameter, Pore Throat, Connectivity between pore, Relative Permeability, Contact angle, Capillary Pressure). Is there any other macro or plugin for this ?
Image was upload above : Thinsection_Sandstone.jpeg > Scale: 150 pixels = 50 mm > Blue color showing Pore space.
8-bit grayscale image :
To calculate Porosity, I am using BoneJ Plugin > Fraction > Area/Volume Fraction and Result table shows Porosity(Area Ratio).
To Calculate Pore Diameter, I am using BioVoxxel Plugin > Extended Particle Analyzer and Result can’t shows. It is showing error like this:
Error …Exception >
(Fiji Is Just) ImageJ 2.0.0-rc-69/1.52i; Java 1.8.0_172 [64-bit]; Windows 7 6.1; 97MB of 1511MB (6%) java.lang.IllegalArgumentException: Row out of range at ij.measure.ResultsTable.getValue(ResultsTable.java:387) at Extended_Particle_Analyzer.particleAnalysis(Extended_Particle_Analyzer.java:475) at Extended_Particle_Analyzer.run(Extended_Particle_Analyzer.java:321) at ij.plugin.filter.PlugInFilterRunner.processOneImage(PlugInFilterRunner.java:266) at ij.plugin.filter.PlugInFilterRunner.<init>(PlugInFilterRunner.java:114) at ij.IJ.runUserPlugIn(IJ.java:230) at ij.IJ.runPlugIn(IJ.java:192) at ij.Executer.runCommand(Executer.java:137) at ij.Executer.run(Executer.java:66) at java.lang.Thread.run(Thread.java:748) **
So I am Using Analyze Particles… Tools > size: 0-infinity, Circularity: 0-1 and Result table shows Area, Perimeter, Circularity, Aspect Ratio, Roundness, Solidity then How could i analyzed, what is the diameter of pore space in 2D_Thinsection_sandstone Image ?
To calculate Pore Throat, I am using Watershed Algorithm but could not understood its result. ** Should told me about that algorithm & How it works ?**
Right now i’m struggeling to find a way to calculate my pore diameter, pore throat, relative permeability and capillary pressure between the connected pores.
Is there a common way to do it? or Plugin available for it ?
I would really appreciate it if you can give me some answers to my questions!
Thanks a lot!
