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 roiSize);

Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib

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.
