FFT Denoise and Spectral Density Scope

[fred_76]

Hi

 

I was looking at the Antinoise FFT for strong watermarking of photos.

 

Why do you show all the XY spectrum ? As it is a centraly symetrical graph, you may only show whether the positive Y part, or the positive X part of the spectrum. By doing so, you will have a gain in space, and not show identical (but symetrical) values.

 

Also, why the spectrum shown in the Antinoise FFT window is different to the spectrum shown in the Scope Spectral Density window ?
