Functions

NVCVStatus cvcudaBoxBlurCreate(NVCVOperatorHandle *handle)

Constructs an instance of the BoxBlur operator.

Parameters:

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

  • Must not be NULL.

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 cvcudaBoxBlurSubmit(NVCVOperatorHandle handle, cudaStream_t stream, NVCVTensorHandle in, NVCVTensorHandle out, const NVCVBlurBoxesI bboxes)

Executes the BoxBlur operation on the given cuda stream. This operation does not wait for completion.

Parameters:

  • handle – [in] Handle to the operator instance created by cvcudaBoxBlurCreate.

    • Must not be NULL.

  • stream – [in] CUDA stream on which the operation is enqueued; execution may continue asynchronously.

  • in – [in] Input tensor that supplies source pixels. It remains unchanged when out is a distinct tensor.

  • out – [out] Output tensor. Its shape, layout, and data type must match the input; it may alias the input.

  • bboxes – [in] Per-sample blur boxes in input-tensor coordinates; its batch count must match the input batch.

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.
