I gave some details in my post above.
I use threshold to categorise whether it is noise or signal. If deviation is more than threshold signal.
Eventhough the interference would be same over the image, it occurred to me that our eyes may be playing tricks and so notice it more in darker areas. Thats the reason to introduce amp factor.

Anyway ... so by default does 16 mean we start at 32/width and remove periodic frequencies? What's the period? Do you remove or reduce them? Is the 5% threshold based upon DC as the max?

Lambda default is 16. Lambda has a relation with wavelength (along width axis) of the periodic noise. I use it as a span over which find deviations and using threshold and amp factors correct. Thats the reason some smoothening may be seen in the result. I do not per se use any other smoothening.

[B]Here is my try at this..... No thresholding the black. And i did not smooth after the filter. I was really just guessing.[B]

Its not clear to me whether you are using my plugin or your own. I find that the white streaks in the black areas, a spot in one eye and still slightly visible diagonal noise are somewhat unsatisfactory. There appears to be much less smoothening than in my example. If you are using my plugin then there must be a bug which is producing those white streaks.
