[−][src]Function opencv::cudaarithm::create_dft

pub fn create_dft(dft_size: Size, flags: i32) -> Result<Ptr<dyn DFT>>

Creates implementation for cuda::DFT.

Parameters

  • dft_size: The image size.
  • flags: Optional flags:
  • DFT_ROWS transforms each individual row of the source matrix.
  • DFT_SCALE scales the result: divide it by the number of elements in the transform (obtained from dft_size ).
  • DFT_INVERSE inverts DFT. Use for complex-complex cases (real-complex and complex-real cases are always forward and inverse, respectively).
  • DFT_COMPLEX_INPUT Specifies that inputs will be complex with 2 channels.
  • DFT_REAL_OUTPUT specifies the output as real. The source matrix is the result of real-complex transform, so the destination matrix must be real.
