I need help measuring the radius of the filament on the image bellow.
So far my approach is to binarize the image and fill holes, which results in the next image BW
What I am trying to do next is to find the centerline and measure the radius normal to that center line. However this is where I fail. To find the centerline I first tried using bwskel, but the results where unsatisfactory.
The result is
If I close in yu can see that the center of the green lines do not represent the centerline :(
And this is where I stand. Any hep to obtain a better centerline or to find a way to measure the radius as a function of the arc length is very much apreaciated
Thank you all for your help,
