I am trying to figure how to use function dft to create time series from single frequency component. For example, if I have to create it from single 10kHz sin, how should i initialize input object ( Mat src)? Thank you,

You do know that the dft function is a function that calculates the dft on an imput image, not on image signals. This means you need to represent your signal as an image first.
