Functions to create noise samples of different distributions.

Functions

poisson_noise(intensity[, seed])	Poisson distributed noise with given intensity.
salt_pepper_noise(vector[, fraction, …])	Add salt and pepper noise to vector.
uniform_noise(space[, low, high, seed])	Uniformly distributed noise in space, pointwise U(low, high).
white_noise(space[, mean, stddev, seed])	Standard gaussian noise in space, pointwise N(mean, stddev**2).
