Title: Radial Symmetries in DBE
Post by: astroedo on 2018 September 09 12:59:55
Hi PI Team,

I was experimenting with Symmetries on DBE and I've found a strange behavior on astronomical images, so I've tried with "synthetic" gradients.
It seems, when symmetries are used, that the resulting gradient is image size-ratio dependent.
As you can see on the attached images, i've created a symmetric circular gradient.
On a square image the resulting DBE gradient is circular.
With the same sample geometry, on a rectangular image, is elliptic.

Am I making something wrong or is it a BUG?

Thank you
