NoiseGaussianInit,
NoiseGaussianInitFp
Initializes parameters
for generating noise
signal with Gaussian
distribution.
void iplNoiseGaussianInit ( IplINoiseParam* noiseParam ,
unsigned int
seed , int mean , int stDev );
void iplNoiseGaussianInitFp ( IplINoiseParam* noiseParam ,
unsigned int
seed , float mean , float stDev );
noiseParam Pointer to the structure that contains parameters
for the noise generator.
seed The initial seed value for the pseudo-random
number generator.
mean The mean of the Gaussian distribution.
stDev The standard deviation of the Gaussian
distribution.
Discussion
Use functions iplNoiseGaussianInit(), iplNoiseGaussianInitFp()
to initialize the noiseParam structure if you want to generate the noise
signal with Gaussian distribution that has the mean value
mean and
standard deviation
stDev . After that you can call the iplNoiseImage()
function, which actually generates and adds the noise signal.
