2D FFT

  • dear all, one of our customer is interested in processing incoming images with 2D FFT, FFT operator in VA is 1D FFT.


    In order to have 2D FFT he has to apply FFT to line first and after this to column



    Do you have example or ideas on how to implement this?



    grazie

  • Dear Pier,

    Sorry for the late reply. You can see an example for the usage of the fft operator in the example under:

    Processing/Advanced/FastFourierTransform

    Sadly, the fft operator only performs a one dimensional fft as you mentioned before.

    If your customer wants to perform it first on the rows, and after this one the colums, my fastest shot would be to try to transpose the image in a second step.

    I will investigate this further and will come back when I new information for you.


    Regards
