Performs two-dimensional filtering on a block.
IppStatus ippiFilter8x8_H261_8u_C1R(Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep);
pSrc |
Pointer to the origin of the source block. |
srcStep |
Width in bytes of the source image plane. |
pDst |
Pointer to the origin of the destination block. |
dstStep |
Width in bytes of the destination image plane. |
The function ippiFilter8x8_H261_8u_C1R is declared in the ippvc.h header file. This function performs filtering on an 8x8 block as specified in [ITUH261], subclause 3.2.3. The two-dimensional filter may be used in both encoder and decoder to modify the prediction. The application of the filter to a macroblock (to all six blocks) is signaled in the MTYPE (macroblock type) codeword.
This function is used in the H.261 encoder and decoder included into Intel IPP Samples. See introduction to H.261.
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error condition if at least one of the specified pointers is NULL. |
