Dilate3x3

Performs dilation of an image using a 3x3 mask.

Syntax

IppStatus ippiDilate3x3_64f_C1R(const Ipp64f*
pSrc
, int
srcStep
, Ipp<datatype>*
pDst
, int
dstStep
, IppiSize

Parameters
pSrc
Pointer to the source image ROI.
srcStep
Distance in bytes between starts of consecutive lines in the source image.
pDst
Pointer to the destination image ROI.
dstStep
Distance in bytes between starts of consecutive lines in the destination image.
roiSize
Size of the source and destination ROI in pixels.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function performs dilation of a rectangular ROI area inside a 2D image using a symmetric 3x3 mask.
Source and destination images can be of different sizes, but the ROI size is the same for both images. The output pixel is set to the maximum of the corresponding input pixel and its eight neighboring pixels.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr
Indicates an error condition if
pSrc
or
pDst
is
NULL
.
ippStsSizeErr
Indicates an error condition if
roiSize
has a field with zero or negative value.
ippStsStepErr
Indicates an error condition if
srcStep
or
dstStep
has a zero or negative value.
