Parameters:

  • handle – [in] Handle to the operator.

    • Must not be NULL.

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

  • in – [in] input tensor / image batch.

  • out – [out] output tensor / image batch.

  • interpolation – [in] Interpolation method to be used, see NVCVInterpolationType for more details.

Return values:

Functions

NVCVStatus cvcudaResizeCreate(NVCVOperatorHandle *handle)

Constructs and an instance of the resize 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.
