FilterMedianGetSize

Computes the size of the filter specification structure and the size of the work buffer for 3D image processing with a median filter.

Syntax

IppStatus ipprFilterMedianGetSize(IpprVolume maskVolume, IpprVolume dstRoiVolume, IppDataType dataType, int numChannels, int* pSpecSize, int* pBufferSize);

Threading Layer (TL) function

IppStatus ipprFilterMedianGetSize_T(IpprVolume maskVolume, IpprVolume dstRoiVolume, IppDataType dataType, int numChannels, int* pSpecSize, int* pBufferSize);

Parameters

maskVolume	Size of the mask volume.
dstRoiVolume	Maximal size of the destination image ROI (in pixels).
dataType	Data type of the source image. Possible values are ipp8u, ipp16u, ipp16s, ipp32f, and ipp64f.
numChannels	Number of channels in the image. Possible value is 1.
pSpecSize	Pointer to the size of the filter specification structure.
pBufferSize	Pointer to the size of the work buffer required for filtering.

Description

This function operates with VOI. This function computes the size of the filter specification structure pSpec and the size of the buffer required for 3D image filtering operations with a median filter. Call this function before using the ipprFilterMedianInit function.

Return Values

ippStsNoErr	Indicates no error condition. Any other value indicates an error condition.
ippStsNullPtrErr	Indicates an error condition if the pSpecSize or pBufferSize pointer is NULL.
ippStsSizeErr	Indicates an error condition if dstRoiVolume or maskVolume has a field with zero or negative value.
ippStsChannelErr	Indicates an error condition if numChannels has an illegal value.
ippStsDataTypeErr	Indicates an error condition if dataType has an illegal value.
