noise_white {ambient} | R Documentation |
White noise is a random noise with equal intensities at different frequencies. It is most well-known as what appeared on old televisions when no signal was found.
noise_white(dim, frequency = 0.01, pertubation = "none", pertubation_amplitude = 1)
dim |
The dimensions (height, width, (and depth, (and time))) of the noise to be generated. The length determines the dimensionality of the noise. |
frequency |
Determines the granularity of the features in the noise. |
pertubation |
The pertubation to use. Either |
pertubation_amplitude |
The maximal pertubation distance from the
origin. Ignored if |
If length(dim) == 2
a matrix, if length(dim) %in% c(3, 4)
a 3- or
4-dimensional array.
