Then you catched me on notation & terminology. So this means, the diameter of the used convolution kernel represents the radius of the gaussian? Doesn't seem obvious to me, but if it is like that, well, let it be ...
Means the sqrt's should be taken out of above function to make it "correct" - and tsp should adjust his plugin too, since it seems to interpret the gaussian radius wrongly as well.

Sure. I only wanted to point out that blurring with a large radius is an *essential* part of the proposed method. Your used blurring with blur(0.2) has so little of the wanted effect, that the effect of the initial script is almost the same as

levels( 0,1.0,255, 10,245 )

which isn't that revolutionary to be used as a trick. It has to be a big gauss, else you're only doing this simple levels squishing, but in a more complicated way.
