Calculates the dot product of taps vector and columns of the specified set of strows.
Syntax
IppStatus ippiDotProdCol_32f_L2(const Ipp32f** const ppSrcRow[], const Ipp32f* pTaps, int tapsLen, Ipp32f* pDst, int width);
Parameters
ppSrcRow |
Pointer to the set of strows. |
pTaps |
Pointer to the taps vector. |
tapsLen |
Length of taps vector, is equal to the number of strows. |
pDst |
Pointer to the destination strow. |
width |
Width of the source and destination strows. |
Description
The function ippiDotProdCol is declared in the ippi.h file.
This function calculates the dot product of filter taps vector pTaps and columns of the specified set of the strows ppSrcRow. The computations are performed in accordance with the following formula:
It is useful for external vertical filtering pipeline implementation.
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error. |
ippStsNullPtrErr |
Indicates an error condition if one of the specified pointers is NULL. |
ippStsSizeErr |
Indicates an error condition if width is less than or equal to 0. |
