SSD8x8

Evaluates sum of squares of differences between current and reference 8X8 blocks.

Syntax

IppStatus ippiSSD8x8_8u32s_C1R(const Ipp8u* srcStep, int srcCurStep, const Ipp8u* pSrcRef, int srcRefStep, Ipp32s* pDst, Ipp32s mcType);

Parameters

pSrc	Pointer to the current block of specified size.
srcCurStep	Step of the current block, specifying width of the block in bytes.
pSrcRef	Pointer to the reference block of specified size.
srcRefStep	Step of the reference block, specifying width of the block in bytes.
pDst	Pointer to the sum of square difference between all elements in the current and reference blocks.
mcType	MC type IPPVC_MC_APX.

Description

This function is declared in the ippvc.h header file. The function ippiSSD8x8_8u32s_C1R evaluates the sum of square difference between all the elements in the current block and corresponding elements in the reference block. The result is stored in integer pDst.

Let us denote the pel which lies at the crossing of i^th row and j^th column of the current block as block[i,j] and the pel which lies at the crossing of i^th row and j^th column of the reference block as ref_block[i,j]. Then

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when at least one input pointer is NULL.
