Parameters
pHOGSpec
Pointer to the HOG context structure.
pWinDescriptorSize
Pointer to the size of the descriptor window, in bytes.
Description
This function computes the size of the buffer for a single detection window. If the subsequent call(s) of the HOG function target processing of multiple detection windows, the size of the buffer must be increased proportionally.
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
.
ippStsContextmatchErr
Indicates an error when the context parameter does not match the operation.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
