Computes the size of the HOG descriptor.

Syntax

IppStatus ippiHOGGetDescriptorSize(const IppiHOGSpec* pHOGSpec, int* pWinDescriptorSize);

Include Files

ippi.h

Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib

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.
