ToyNoise1: Generate a realization of the Toy Noise 1.
Description
Generate a realization of the Toy Noise 1.Usage
ToyNoise1(n = 1, Ns = 64, model = list(), theta = 0.1, l1 = 1,
l2 = 4, tau = 12)
Arguments
n
The number of realizations to produce.
Ns
Number of pixels of the result in one direction. The resulting
picture will have Ns x Ns pixels.
model
The correlation structure of the noise, as used by arima.sim.
Default is list() which gives i.i.d. noise.
theta
Bandwidth of kernel used to smooth the noise.
l1, l2
Pixel size of the noise blocks in either side of the domain.
See main reference for details.
tau
Scaling factor with which noise is multiplied after generation.
Value
A list containing x and y, the coordinates of the grid and
z and array of dimensions c(64,64,n) giving n reallizations of the
Toy Noise 1.
