Parameters
pConfig
Pointer to the HOG context structure.
pHOGSpecSize
Pointer to the size of the HOG context structure, in bytes.
Description
This function checks the parameters of the HOG configuration and computes the size, in bytes, of the HOG context structure
pHOGSpecSize
.
For an example on how to use this function, refer to the example provided with the HOG function description.
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
