Parameters

pConfig

Pointer to the HOG context structure.

pHOGSpecSize

Pointer to the size of the HOG context structure, in bytes.

Return Values

ippStsNoErr

Indicates no error. Any other value indicates an error.

ippStsNullPtrErr

Indicates an error when one of the specified pointers is NULL.

ippStsSizeErr

Indicates an error when one of the winSize fields in the pConfig parameter has a zero or negative value.

ippStsNotSupportedModeErr

Indicates an error in HOG configuration:

• cellSize is less than 2, or more than IPP_HOG_MAX_CELL

• cellSize is more than blockSize, or blockSize is more than IPP_HOG_MAX_BLOCK

• blockSize is not a multiple of cellSize

• Block does not have 2x2 cell geometry

• blockStride is not a multiple of cellSize

• Detection window size is not a multiple of blockStride

• nbins is less than 2, or more than IPP_HOG_MAX_BINS

• sigma or threshold value is less than, or equal to zero
