NVCVStatus cvcudaJointBilateralFilterCreate(NVCVOperatorHandle *handle)
Constructs and an instance of the Joint Bilateral Filter 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 cvcudaJointBilateralFilterSubmit(NVCVOperatorHandle handle, cudaStream_t stream, NVCVTensorHandle in, NVCVTensorHandle inColor, NVCVTensorHandle out, int diameter, float sigmaColor, float sigmaSpace, NVCVBorderType borderMode)
Executes the JointBilateralFilter operation on the given cuda stream. This operation does not wait for completion.
Limitations:
Destination must be same format and size as source
