grain and particle analysis with line intersection method
Updated 2 Apr 2012
This program allows you to analyze the size of grains in a micrograph with the intersection method arranged in a user-friendly GUI.
After loading the micrograph the program puts lines on the surface. Now you have to use the cursor to click on the intercept of the lines with the grain boundaries. Concluding you get an editable and savable histogram and a txt-file containing the length of the grains.
You can also analyze existing txt-files to get the histogram (including lognormal distribution fitting) or an empirical cumulative distribution function plot of different micrographs and you can compare them in one chart.
In addition you get a lot of features (e.g. rotate image) and fully control about many settings.
The GUI should be mostly self-explanatory, anyway I recommend this screencast, in which all features are explained.

This submission based on the idea and code of Matthias Funk from the Karlsruhe Institute of Technology (KIT), IAM-WBM, Nachwuchsgruppe für microreliability. This project was financed by DFG-SFB499N01.
The lognormal distribution fitting in histogram was created by Jochen Lohmiller based on:

added contact data; 'Line Cut' = 'intersection method'
added all Screencasts to YouTube; small fix in CDF (to avoid errors at multiple file selection)
