VQCodeBookInitAlloc

Creates and initializes the codebook structure.

Syntax

IppStatus ippsVQCodeBookInitAlloc_32f(const Ipp32f* pInputTable, IppsVQCodeBookState_32f** ppCodeBook, int step, int height);

Parameters

pInputTable	Pointer to the codebook table of the size step * height containing height quantization vectors of the length step.
ppCodeBook	Doubleo pointer to the codebook state structure.
step	Step to the next line in the table InputTable, quantization vector length.
height	Table height, number of quantization vectors.

Description

The function ippsVQCodeBookInitAlloc is declared in the ippac.h header file. This function allocates memory and initializes the state structure that contains the codebook and additional information needed for the search operation. This structure is used ippsVQPreliminarySelect, ippsVQMainSelect, ippsVQIndexSelect, and ippsVQReconstruction.

To free the memory allocated by this function, use the function ippsVQCodeBookFree.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when ppCodeBook or pInputTable pointer is NULL.
ippStsMemAllocErr	Indicates an error when no memory is allocated.
ippStsSizeErr	Indicates an error when step or height is less than or equal to 0.
