Parameters

pSrc

Array of pointers to the planes in the source volume.

srcStep

Distance, in bytes, between the starting points of consecutive lines in each plane of the source volume.

srcPlaneStep

Distance, in bytes, between the starting points of consecutive images in every plane of the source volume.

pDst

Array of pointers to the planes in the destination volume.

dstStep

Distance, in bytes, between the starting points of consecutive lines in each plane of the destination volume.

dstPlaneStep

Distance, in bytes, between the starting points of consecutive images in every plane of the source volume.

dstRoiVolume

Volume of the destination ROI in pixels.

borderType

Type of the border. Possible values are:

ipprBorderInMem	Border is obtained from the source image pixels in memory.
ipprBorderRepl	Border is replicated from the edge pixels.
ipprBorderConst	Border is replicated from the edge pixels.

pBorderValue

Pointer to the constant value to assign to pixels of the constant border.

pSpec

Pointer to the filter specification structure.

pBuffer

Pointer to the work buffer for filtering operations.

Description

Before using this function, you need to initialize the filter specification structure for 3D image processing using the ipprFilterMedianInit function.

This function operates with VOI. This function performs median filtering on a source image with the volume. Type of the image border is defined by the value of the border parameter.

Return Values

ippStsNoErr	Indicates no error condition. Any other value indicates an error condition.
ippStsStepErr	Indicates an error condition if srcPlaneStep, srcStep, dstPlaneStep, or dstStep has a field with negative value.
ippStsNullPtrErr	Indicates an error condition if the pSrc, pDst, pSpec, pBorderValue, or pBuffer pointer is NULL.
ippStsSizeErr	Indicates an error condition if dstRoiVolume has a field with zero or negative value.
