Performs inverse quantization on a block.
IppStatus ippiQuantInv_DV_16s_C1I(Ipp16s* pSrcDst, Ipp16s* pDequantTable);
pSrcDst |
Pointer to the block. |
pDequantTable |
Pointer to the dequantization table. |
This function is declared in the ippvc.h header file. The function ippiQuantInv_DV_16s_C1I performs inverse quantization on a block. Each of the decoded DCT coefficients in the block should be inverse quantized through multiplying by a corresponding value from the weighting matrix and division on 214. Selection of dequantization table depends of the block type.
See Example "Inverse Quantization Tables" and Example "ippiQuantInv_DV_16s_C1I Usage" for an example of the function usage.
This function is used in the DV decoder included into Intel IPP Samples. See introduction to DV.
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when at least one input pointer is NULL. |
