Erode3x3

Performs erosion of an image using a 3x3 mask.

Syntax

IppStatus ippiErode3x3_64f_C1R(const Ipp64f* pSrc, int srcStep, Ipp64f* pDst, int dstStep, IppiSize roiSize);

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 erosion of a rectangular ROI area inside a 2D image using a symmetric 3x3 mask.

Source and destination images can have different size, but the ROI size is the same for both images. The output pixel is set to the minimum of the corresponding input pixel and its 8 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 a zero or negative value.
ippStsStepErr	Indicates an error condition if srcStep or dstStep has a zero or negative value.
