When comparing the histograms of both samples please note the scale of the rel. frequency-axis [%]. (These histograms are density functions, i.e. their integrals are one.)
To discriminate between samples it may be sufficient to use the global “Orientation Salience Histograms”. I’m not familiar with this kind of data and I don’t know what’s important, so the decision is yours.
The analyses were done using this ImageJ-plugin. Plugins performing similarly are available from other download sites.
So many thanks! That is super helpful! I have used OrientationJ ImageJ plugin but it seems not really what I want. I tried the plugin you recommended it at least work so good on the global analysis for me!
Thanks again! I will update you with any further findings I get.
There is actually a plugin named “Waveness, Roughness” although I do not know if it comes with the install yet. If not you can get it on the plugins site and is quite straightforward and easy to use.
