Functions

NVCVStatus cvcudaCvtColorCreate(NVCVOperatorHandle *handle)

Constructs an instance of the CvtColor (convert color operation).

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 cvcudaCvtColorSubmit(NVCVOperatorHandle handle, cudaStream_t stream, NVCVTensorHandle in, NVCVTensorHandle out, NVCVColorConversionCode code)

Executes the CvtColor (convert color) operation on the given cuda stream. This operation does not wait for completion.

Parameters

  • handle – [in] Handle to the operator.

    • Must not be NULL.

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

  • in – [in] Input tensor.

  • out – [out] Output tensor.

  • code – [in] Color conversion code, NVCVColorConversionCode.

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.
