Do Radial Gradients on your FFT September 16th, 2009
Patrick Stein

I have now added radial gradients to my FFT Paint application. Here, I wiped out an image entirely and painted my own data using only the new gradient tool to come up with this starting point:

mag_grad  phase_grad

This is what it looks like if I do the inverse FFT of that data. It’s not an incredibly interesting result, but it does show the power.

mag_inv  phase_inv

Here is another example of a starting point made entirely with the gradient paint tool:

conc_tm  conc_tp

And, its resulting image when I do the inverse transform:

conc_rm  conc_rp
