)#

Constructs and an instance of the HOG operator.

Limitations:

Allowed

RGB8p

Yes

Image size constraints:

  • 576x576 is the only supported image size.

Output tensor: Data Layout: [CHW]

Tensor size constraints:

  • 18x144x144 is the only supported tensor size.

Parameters:

  • handle – [out] Where the operator instance handle will be written to.

    • Must not be NULL.

  • imageRequirements – [in] Pointer to the NVCVImageRequirements structure which contains input image width, height and format information.

  • tensorRequirements – [in] Pointer to the NVCVTensorRequirements structure which contains output tensor rank, shape, layout and data type information.

Return values:

  • NVCV_ERROR_INVALID_ARGUMENT – Handle is null.

  • NVCV_ERROR_OUT_OF_MEMORY – Not enough memory to create the operator.

  • NVCV_SUCCESS – Operation executed successfully.

NVCVStatus pvaHOGSubmit(
NVCVOperatorHandle handle,
cupvaStream_t stream,
NVCVImageHandle const in,
NVCVTensorHandle const out,
)#

Submits the HOG operator to a cuPVA stream.

Parameters:

  • handle – [in] Handle to the operator.

    • Must not be NULL.

  • stream – [in] Handle to a valid cuPVA stream.

  • in – [in] Input image handle.

  • out – [out] Output tensor handle.

Return values:

  • NVCV_ERROR_INVALID_ARGUMENT – Some parameter is outside valid range.

  • NVCV_ERROR_INTERNAL – Internal error in the operator, invalid types passed in.

  • NVCV_SUCCESS – Operation executed successfully.

  • out – [out] Output tensor handle.

Return values:

  • NVCV_ERROR_INVALID_ARGUMENT – Some parameter is outside valid range.

  • NVCV_ERROR_INTERNAL – Internal error in the operator, invalid types passed in.

  • NVCV_SUCCESS – Operation executed successfully.
