Inputs (3)
| Name | Type | Default | Description |
|---|---|---|---|
| src | NPARRAY | input floating-point real or complex array. A data array (points / matrix), NOT an image - only an NPARRAY link is accepted here. | |
| flagsopt | STRING | none (0) | operation flags (see dft and #DftFlags). cv2.idft flags: one of none (0) plus any of DFT_COMPLEX_OUTPUT, DFT_REAL_OUTPUT, DFT_SCALE, DFT_INVERSE, DFT_ROWS, DFT_COMPLEX_INPUT, pipe-joined (e.g. "none (0) | DFT_COMPLEX_OUTPUT"). In the UI this renders as a dropdown with one toggle per flag. |
| nonzeroRowsopt | INT | 0-2147483648–2147483647 | number of dst rows to process; the rest of the rows have undefined content (see the convolution sample in dft description. Preset to the OpenCV default (0). |
