Something really strange happened to me. Yesterday I replaced my previous 1.8 version by the newer 1.8 RC7 just to install the TVGdenoise module and give it a try.
Everything worked ok, after installing 1.8RC7 a popup window informed about 7 available updates (one of them the TVGdenoise module), I installed them and restarted PI. Then the TVGdenoise module was there under NoiseReduction folder. I was trying it with an old image and got some promising results.
This morning I have started PI and the TVGdenoise module was not there any more, I can't find it under NoiseReduction neither under AllProcesses. Curiously, I click on "View Installed Updates" and it's there, but there's no way to find it under the process menu.
I'm running PI 64-bit version for Windows. Any help is welcome.

So far I resisted on the 1.8 RCxxxx upgrades, sticking with 1.7, but finally this tool got my attention and helped me to made my mind. I installed RC7 yesterday night and tried TGV on some (very noisy) Ha and O3 frames.

Indeed, it seems to be a very strong tool BUT, where is the preview button and where is the mask generator from ACDR ?   >:D

It is a really pain already due to lack of documentation, how about a real time preview window to assist us to experiment?  And no, applying to previews is not the same.  Com'on guys, you have the code from ACDR, reuse it and make this tool the best ever !!!  ;) (I may offer to assist in adding the code for free, but I'll have to figure out a few things first, long time when I had a compiler on my laptop :angel: )

Update on my previous post. I uninstalled PI RC7 and installed it again from scrath including the 7 updates and the TVGmodule is there again. I have closed and started PI several times and it keeps there. However it's very strange that it disappeared the first time.

Regarding the results yielded by the tool, I don't have a clear opinion yet. I tried many combinations of parameters and tried to fine-tune them the most, but it always produced a patchy background on my DSLR linear image. ACDNR did a lot better keeping a smoother and patches free background.

Increase the number of iterations. Use 300 or 500. Then play only with the noise amplitude and strength parameters (in that order).

Hello everyone, I installed the latest updates but I can not see TGVDenoise despite being mentioned in the Installed Updates window.
Thank you.

Wow!  The following are small sections of the original images.  There are too few subs and therefore very noisy.  My attempt at boosting the central blue saturation is crude but I was reasonably happy.  Image01 is before, Image02 is after TVG!

cfranks:

I don't know if boosting the blues boosted the noise there.  Perhaps applying the TVG before applying the blue boost would lead to a more "homogeneous" noisiness in the final image.  I do enjoy the color!

I find it can be a tad bit more subtle than ACDNR and I don't need to use a mask.  Is that what everyone else is finding out too?

Hi

I have been looking at TGVDenoise since its release and it seems I am getting somewhere with it. Have a look at the attached for the settings I have been using.
