Parameters
- pState
- Pointer to the gray-kernel morphology state structure.
- roiSize
- Maximal size of the image ROI in pixels, that can be processed using the allocated structure.
- pMask
- Pointer to the mask.
- maskSize
- Size of the mask in pixels.
- anchor
- Coordinates of the anchor cell.
Description
This function operates with ROI (see
Regions of Interest in Intel IPP
).
This function initializes the gray-kernel morphology state structure
pState
in the external buffer. Its size should be computed by the function
MorphGrayGetSize
. It is used by the functions
GrayDilateBorder
and
GrayErodeBorder
that perform gray-kernel dilation and erosion of the source image pixels corresponding to the specified
pMask
of size
maskSize
. The anchor cell
anchor
is positioned in the arbitrary point in the mask and is used for positioning the mask.
The structure can be used to process images with ROI that does not exceed the specified maximum width and height
roiSize
.
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error when one of the specified pointers isNULL.
- ippStsSizeErr
- Indicates an error condition ifmaskSizeor ifroiSizehas a field with a zero or negative value.
- ippStsAnchorErr
- Indicates an error ifanchoris outside the mask.
