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 ifpSrcDstorpSeedpointer isNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSizehas a field with zero or negative value.
- ippStsStepErr
- Indicates an error condition ifsrcDstStephas a zero or negative value.
