Functions

NVCVStatus cvcudaBndBoxCreate(NVCVOperatorHandle *handle)

Constructs and an instance of the BndBox operator.

Parameters:

handle – [out] Where the image 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 cvcudaBndBoxSubmit(NVCVOperatorHandle handle, cudaStream_t stream, NVCVTensorHandle in, NVCVTensorHandle out, const NVCVBndBoxesI bboxes)

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