pub fn idct(
src: &dyn ToInputArray,
dst: &mut dyn ToOutputArray,
flags: i32
) -> Result<()>
Calculates the inverse Discrete Cosine Transform of a 1D or 2D array.
idct(src, dst, flags) is equivalent to dct(src, dst, flags | DCT_INVERSE).
Parameters
- src: input floating-point single-channel array.
- dst: output array of the same size and type as src.
- flags: operation flags.
