Function Documentation

AddGaussNoise()

std::unique_ptr< Image > AddGaussNoise ( const Image &  image, double  mean, double  stdDev, int  seed  )

inline

Add noise with Gaussian distribution to an image.

Parameters

[in]	image	Image to add the noise to.
[in]	mean	Mean value of the gaussian distribution.
[in]	stdDev	Standard deviation of the gaussian distribution.
[in]	seed	Seed value for the pseudo random number generator.

Returns

Result image with added noise.

Exceptions

Any	exception derived from std::exception including CvbException.

Pixel values that exceed the image's value range are saturated at the minimum and maximum value.

AddUniformNoise()

std::unique_ptr< Image > AddUniformNoise ( const Image &  image, double  lowest, double  highest, int  seed  )

inline

Add noise with uniform distribution to an image.

Parameters

[in]	image	Image to add the noise to.
[in]	lowest	Lower bound of the uniform distribution.
[in]	highest	Upper bound of the uniform distribution.
[in]	seed	Seed value for the pseudo random number generator.

Returns

Result image with added noise.

Exceptions

Any	exception derived from std::exception including CvbException.

Pixel values that exceed the image's value range are saturated at the minimum and maximum value.
