Parameters
ppSrcRow |
Pointer to the set of rows. |
pTaps |
Pointer to the taps vector. |
tapsLen |
Length of taps vector, is equal to the number of rows. |
pDst |
Pointer to the destination row. |
width |
Width of the source and destination rows. |
Description
This function calculates the dot product of taps vector pTaps and columns of the specified set of the rows ppSrcRow. 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. |
