#28 Question: A question about 2D FFT and wavelets

Hello,

I am having a problem with a 2D FFT transform. It is an function that
has an discontinuity and therefore I have the Gibbs-Wilbraham
phenomenon in the solution.

I have read that a wavelet function could improve this shortcoming.
Could you please recommend a method for a 2D function (i.e. f(x,y),
where x,y, range from +/- inf)

Thanks,

Johan
