Can anyone help me to understand how "Relative box sizes" works when one
selects this kind of generating the box size series?
My feeling is that using this option the fractal dimension is more
accurate at least in some types of solid structures (even a rotated
square). On the other side the number of boxes as given in the result
window ranges only from 6 to 20 depending on the value of the largest grid
(not a monotonic dependence though). In addition, the option "box sizes
per scan" does not seem to do anything in this case. Even worse, "Sliding
Box Lacunarity Scan" does not work at all if I "Use Relative Sizes".
My guess is that "Use default box sizes" generates a linear series from
the smalles to the biggest grid by adding the smallest increment, but I
have no idea how "Use Relative Sizes" works considering that power series
and scaled series (exponential?) are separated options.
Thank you.
