Detailed Description

template<class TInputImage>
class rtk::AdditiveGaussianNoiseImageFilter< TInputImage >

Adds Gaussian noise to the input image.

Adds noise to the input image according to a Gaussian normal variate distribution. The user supplies the mean \(\bar{x}\) and standard deviation \(\sigma\), such that the output is given by:

\[ v_{out} = v_{in} + \bar{x} + \sigma * G(d) \]

where G() is the Gaussian generator and d is the seed. A particular seed can be specified in order to perform repeatable tests.

Test:
