Dear
all,
at
one can read the
following
"The fractal dimension is estimated
separately for each profile from the log-log plot of cell count against step
size (D = 2 - slope, where 1 <= D <= 2). The average of these values plus
one provides an estimate of the surface fractal dimension."
Burrough's method
(using the slope of the log-log plot of the semivariogram to calculate the
fractal dimension of 1 dimensional transect or profile) could thus be extended
to a 2 D case (a surface). Has anyone references discussing the use of
Burrough's method when applied to a 2 D case?
Unless one considers
the investigated phenomenon completely isotropic, averaging the fractal
dimensions derived from the slopes of directional log-log semivariograms may not
provide any useful/reliable information.
Has someone on the
list any experience with this kind of issue?
Thanks very much for
any help.
Best
regards,
Gregoire
PS: I know there are
other techniques to calculate the fractal dimension of a surface but I'm
only interested in those involving the computation of
the semivariance.
