Estimate the wavelet variance suggested by Rosenberg 2004. 2D only, rectangular box only.
rosenberg( x, theta = seq(0, pi, l = 50), scales = 1:45/180 * pi, steps = 180, include = 0.75 )
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. |
Compute the estimator given in Rosenberg 2004.
