Good afternoon Herbie and Ron DeSpain
thanks for replies.
Yes I wanted to compute the angles of the yellow lines of my original image and I found useful the method described by @Herbie.Thank you Herbie, this is exactly what I needed.
However, Ron despain when you say that median orientation and slope are not the same value, what did you mean? When you sau slope, you mean the little yellow lines on the image? I know these two are not the same value, so what’s the difference then? Cause I think this might be something I’ll look into. If I compute the dominat (preferred) orientation of a little region of interest using e.g. Orientation J measure or dominant direction, then I compute the angles of these little yellow lines, it means these two values will be different. So what’s the difference?
