Solar Eclipse / Druckmullerova's algorithm

Hi, I am new to this forum, I am trying to use the function fnrgf to process a solar eclipse image, the image is a composite taken from many bracketed images.

Does anyone has an example i can copy ?

Thank you

Hello,

There is an example of using fnrgf here: Radial Gradient Filters — sunkit_image 0.5.0 documentation

if you have any questions trying to adapt it let us know and I am sure someone will be able to help.
