SmoothingChroma_HorEdge

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

Syntax

IppStatus ippiSmoothingChroma_HorEdge_VC1_16s8u_C1R( Ipp16s* pSrcDstUpper, Ipp32s srcDstUpperStep, Ipp16s* pSrcDstBottom, Ipp32s srcDstBottomStep, Ipp8u* pDst, Ipp32s dstStep );

IppStatus ippiSmoothingChroma_HorEdge_VC1_16s8u_C2R( Ipp16s* pSrcDstUpperU, Ipp32u srcDstUpperStepU, Ipp16s* pSrcDstBottomU, Ipp32u srcDstBottomStepU, Ipp16s* pSrcDstUpperV, Ipp32u srcDstUpperStepV, Ipp16s* pSrcDstBottomV, Ipp32u srcDstBottomStepV, Ipp8u* pDst, Ipp32u dstStep );

Parameters

pSrcDstUpper	Pointer to the first pixel of the row of the upper block, from which the smoothing starts.
srcDstUpperStep	Step for transfer to the next row in the upper block.
pSrcDstBottom	Pointer to the first pixel of the bottom block.
srcDstBottomStep	Step for transfer to the next row in the bottom block.
pSrcDstUpperU	Pointer to the first pixel of the column of the upper U difference block, from which the smoothing starts.
srcDstUpperStepU	Step for transfer to the next row in the upper U block.
pSrcDstBottomU	Pointer to the first pixel of the bottom U difference block.
srcDstBottomStepU	Step for transfer to the next row in the bottom U block.
pSrcDstUpperV	Pointer to the first pixel of the row of the upper V difference block, from which the smoothing starts.
srcDstUpperStepV	Step for transfer to the next row in the upper V difference block.
pSrcDstBottomV	Pointer to the first pixel of the bottom V block.
srcDstBottomStepV	Step for transfer to the next row in the bottom V difference block.
pDst	Pointer to the first pixel of the bottom block in the Y-plane. For ippiSmoothingChroma_HorEdge_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_HorEdge_VC1_16s8u_C1R and ippiSmoothingChroma_HorEdge_VC1_16s8u_C2R are declared in the ippvc.h file. The function ippiSmoothingChroma_HorEdge_VC1_16s8u_C1R performs smoothing filtering on the horizontal edge (internal or external) of the chroma 8x8 blocks. The function ippiSmoothingChroma_HorEdge_VC1_16s8u_C2R performs smoothing filtering on the horizontal edge (internal or external) of the chroma 8x8 difference and 16x8 plane blocks. See 8.5 of [SMPTE421M].

Horizontal Smoothing Between Two Chroma Block

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.
