Parameters:

  • handle – [in] Handle to the operator.

    • Must not be NULL.

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

Functions

NVCVStatus cvcudaMedianBlurCreate(NVCVOperatorHandle *handle, const int32_t maxVarShapeBatchSize)

Constructs and an instance of the median blur operator.

Parameters:

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

    • Must not be NULL.

  • maxVarShapeBatchSize – [in] maximum batch size for var shape operator

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.
