SmoothingChroma_VerEdge

Performs smoothing filtering on the vertical edge (internal or external) of chroma blocks.

Syntax

IppStatus ippiSmoothingChroma_VerEdge_VC1_16s8u_C1R( Ipp16s* pSrcDstLeft, Ipp32s srcDstLeftStep, Ipp16s* pSrcDstRight, Ipp32s srcDstRightStep, Ipp8u* pDst, Ipp32s dstStep );

IppStatus ippiSmoothingChroma_VerEdge_VC1_16s8u_C2R( Ipp16s* pSrcDstLeftU, Ipp32u srcDstLeftStepU, Ipp16s* pSrcDstRightU, Ipp32u srcDstRightStepU, Ipp16s* pSrcDstLeftV, Ipp32u srcDstLeftStepV, Ipp16s* pSrcDstRightV, Ipp32u srcDstRightStepV, Ipp8u* pDst, Ipp32u dstStep );

Parameters

pSrcDstLeft	Pointer to the first pixel of the column of the left block, from which the smoothing starts.
srcDstLeftStep	Step for transfer to the next row in the left block.
pSrcDstRight	Pointer to the first pixel of the right block.
srcDstRightStep	Step for transfer to the next row in the right block.
pSrcDstLeftU	Pointer to the first pixel of the column of the left U difference block, from which the smoothing starts. `0 UUUUUUUU 1 UUUUUUUU ... 7 UUUUUUUU`
srcDstLeftStepU	Step for transfer to the next row in the left U block.
pSrcDstRightU	Pointer to the first pixel of the right U difference block.
srcDstRightStepU	Step for transfer to the next row in the right U block.
pSrcDstLeftV	Pointer to the first pixel of the column of the left V difference block, from which the smoothing starts. `0 VVVVVVVV 1 VVVVVVVV ... 7 VVVVVVVV`
srcDstLeftStepV	Step for transfer to the next row in the left V difference block.
pSrcDstRightV	Pointer to the first pixel of the right V block.
srcDstRightStepV	Step for transfer to the next row in the right V block.
pDst	Pointer to the first pixel of the right block in the Y-plane. For ippiSmoothingChroma_VerEdge_VC1_16s8u_C2R, pointer to the first pixel of the right block in the UV-plane in the NV12 format: `0 UV UV UV UV UV UV UV UV 1 UV UV UV UV UV UV UV UV ... 7 UV UV UV UV UV UV UV UV`
dstStep	Distance in bytes between starts of the consecutive lines in the Y-plane. For ippiSmoothingChroma_VerEdge_VC1_16s8u_C2R, UV-plane step in bytes.

Description

The functions ippiSmoothingChroma_VerEdge_VC1_16s8u_C1R and ippiSmoothingChroma_VerEdge_VC1_16s8u_C2R are declared in the ippvc.h file. The function ippiSmoothingChroma_VerEdge_VC1_16s8u_C1R performs smoothing filtering on the vertical edge (internal or external) of the chroma 8x8 blocks. The function ippiSmoothingChroma_VerEdge_VC1_16s8u_C2R performs smoothing filtering on the vertical edge (internal or external) of the chroma 8x8 difference and 16x8 plane blocks. See 8.5 of [SMPTE421M].

Vertical Smoothing Between Two Chroma Blocks

All samples of the source block should be within the range [-2048; 2047). After smoothing, all samples of the destination block are within the range [-512, 511).

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error condition when source or destination pointers are NULL.
