Who's going to decipher and implement this?

It's way too complicated for me.

Ah, the Fourier domain.

Maybe the authors can provide a practical recipe. Both are on LinkedIn.

Not gonna happen, ‘cause:

(\$1 / 434 + {6 * 2} - (that horseshoe looking thingy / 2) & * 1 + (4550334 * 0) * (1 / .4545 * (12^3)) (uh, looks like a weird letter “E”) - #@# % * 79 <? <> & == 0) * 0

(Note: for symbol replacements, see the “Symbol Replacements Table.”)

See what I mean?
When you care more about capturing DATA, as opposed to WONDERMENT, you've lost your creative SOUL.

Amazing that he can't do that, eh ?

a1ex, while you're on it... please fix the white balance on these (you should be familiar with white balance by now).

This is the formula : uˆ(ξ) = ˆv(ξ) + ˆv(H(ξ/2)) and g(µ + ξ) + g(µ − ξ).

(in plain English : make a lot of white, and little yellow. yellow is bad).

You got three days.

Thanks

My brother is a maths boy.
He likes this forum because even the people who speak English as their first language don't speak it correctly.
That sentence was an example of itself.

The article basically does what the wavelet transform does... which is essentially jpeg compression.

What about trying something a little simpler like supersampling.

Its really tough stuff. Here's a 'good understanding' abstract for budding coders to look at where adaptive and non-adaptive techniques are currently employed.
