idct¶
Functionality¶
Calculates the inverse Discrete Cosine Transform of a 1D or 2D array.
Inputs¶
- flags_in – DCT_INVERSE, DFT_SCALE, DFT_ROWS, DFT_COMPLEX_OUTPUT, DFT_REAL_OUTPUT
- src_in – Input floating-point single-channel array.
Outputs¶
- dst_out – Output array of the same size and type as src.
