Detailed Description

Alter an image with additive Gaussian white noise.

Additive Gaussian white noise can be modeled as:

\( I = I_0 + N \)
where \( I \) is the observed image, \( I_0 \) is the noise-free image and \( N \) is a normally distributed random variable of mean \( \mu \) and variance \( \sigma^2 \) :
\( N \sim \mathcal{N}(\mu, \sigma^2) \)

The noise is independent of the pixel intensities.
