static Image	Uniform (Image img, double lowest, double highest, int seed)
	Add noise with uniform distribution to an image. Pixel values that exceed the image's value range are saturated at the minimum and maximum value.
static Image	Gauss (Image img, double mean, double stdDev, int seed)
	Add noise with Gaussian distribution to an image. Pixel values that exceed the image's value range are saturated at the minimum and maximum value.

Member Function Documentation

Gauss()

static Image Gauss ( Image img, double mean, double stdDev, int seed )

static

Add noise with Gaussian distribution to an image. Pixel values that exceed the image's value range are saturated at the minimum and maximum value.

Parameters

img	image to add the noise to
mean	mean value of the gaussian distribution
stdDev	standard deviation of the gaussian distribution
seed	seed value for the pseudo random number generator

Returns

the input image with added noise

Exceptions

ArgumentNullException	If the input img is null
ObjectDisposedException	If the input img has already been disposed

Uniform()

static Image Uniform ( Image img, double lowest, double highest, int seed )

static

Add noise with uniform distribution to an image. Pixel values that exceed the image's value range are saturated at the minimum and maximum value.

Parameters

img	image to add the noise to
lowest	lower bound of the uniform distribution
highest	upper bound of the uniform distribution
seed	seed value for the pseudo random number generator

Returns

the input image with added noise

Exceptions

ArgumentNullException	If the input img is null
ObjectDisposedException	If the input img has already been disposed
