I'm just wondering whether the devs managed to overlook this post or so? The filtering algorithm looks so stunning, that if it's not fake, it's kind of revolution . Would it be possible to adopt it for LuxRender somehow? What's your opinion?
As described in the paper, it uses similar tricks to detect edges, however it uses wavelet filtering instead of gaussian blur and is much more efficient than traditional bilateral filtering as is demonstratede by some figures in the paper.
I once tried to de-noise a luxrender-image with wavelet filtering in GIMP - it was awful, destroid all the fine structures and was still noisy (but maybe I didn't fiddle the settings to the very best).
