I started using the Directionality plugin in Fiji (ImageJ) in order to measure the angular position of the hair that is rotating on a droplet.
Here is the orientation map of an example image given by this plugin.
The inferred direction is correct, however the data ‘Direction’ was not incorrect. So I plotted the raw data from the table and I could see the correct peak (in the examle figure between 50 and 60 degrees).
I would like to know how to obtain the correct data given by this peak or what I should do.
I would really appreciate any help.
Thank you very much!
