Estimate the wavelet variance suggested by Rosenberg 2004. 2D only, rectangular box only.
Usage
rosenberg(
x,
theta = seq(0, pi, l = 50),
scales = 1:45/180 * pi,
steps = 180,
include = 0.75
)Arguments
- x
pp, list with $x~coordinates $bbox~bounding box
- theta
directions to estimate the wavelet variance at
- scales
angular scales to average over, in radians.
- steps
divide the half-circle into this many sectors around each point (default: 180)
- include
Only estimate the variance from points in the central region, area fraction given by 'include'. default: 0.5.
