AddRandGauss
Generates random samples with Gaussian distribution and adds them to an image data.
Syntax
IppStatus ippiAddRandGauss_<mod>(Ipp<datatype>* pSrcDst, int srcDstStep, IppiSize roiSize, Ipp<datatype> mean, Ipp<datatype> stDev, unsigned int* pSeed);
Supported values for mod:
8u_C1IR | 16u_C1IR | 16s_C1IR | 32f_C1IR |
8u_C3IR | 16u_C3IR | 16s_C3IR | 32f_C3IR |

Parameters
pSrcDst |
Pointer to the source and destination image ROI. |
srcDstStep |
Distance in bytes between starts of consecutive lines in the source and destination image. |
roiSize |
Size of the image ROI in pixels. |
mean |
The mean of the Gaussian distribution. |
stDev |
The standard deviation of the Gaussian distribution. |
pSeed |
The initial seed value for the pseudo-random number generator. |
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
The function generates samples with Gaussian distribution that have the mean value mean and standard deviation stdev and adds them to a source image ROI pointed to by pSrcDst.
The resulting pixel values that exceed the image data range are saturated to the respective data-range limits. To obtain an image which contains pure noise with Gaussian distribution, call ippiAddRandGauss using a source image with zero data as input.
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error or a warning. |
ippStsNullPtrErr |
Indicates an error condition if pSrcDst or pSeed pointer is NULL. |
ippStsSizeErr |
Indicates an error condition if roiSize has a field with zero or negative value. |
ippStsStepErr |
Indicates an error condition if srcDstStep has a zero or negative value. |
