NVCVStatus cvcudaConvertToCreate(NVCVOperatorHandle *handle)
Constructs and an instance of the ConvertTo 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 cvcudaConvertToSubmit(NVCVOperatorHandle handle, cudaStream_t stream, NVCVTensorHandle in, NVCVTensorHandle out, const double alpha, const double beta)
Executes the ConvertTo operation on the given cuda stream. This operation does not wait for completion.
outputs(x,y) = saturate_cast<out_type>(α * inputs(x, y) + β)
