Open Image Denoise node for DP Filter

[dpont]

Hi,

I uploaded the experimental Open Image Denoise node for DP Filter 2018-2019
at the bottom of the DP Filter page,
this is a separate Windows version,
a bit tricky to install,
so it is necessary to see the readme file before,
also because you will download a few dynamic libraries
from the Intel Open Image Denoise Github site.

Denis.

Thanks Denis

Followed your instructions to the letter and replaced tbb.dll in the Bin folder of LW, LW wont load now because of this, it cant find tbb.dll and yet it is there, so guess im going to have to go back to the safe copy.

My boo boo, copied the wrong file, that will teach me for doing it fast.

This needs a bit more fanfare. Toot, toot!

I'm using an AMD GPU right now so I cannot make use of LW2019's new Nvidia-only GPU denoise option. So this option is appreciated.

No matter how much I tinker with the settings of LW2019's native CPU denoiser, I still cannot get as good a result as this open image denoise node filter. The native CPU denoiser is blurring too much detail. Even with the fewer configuration options, the open image denoise node setup retains the detail. Denoising isn't perfect but this is a big step forward.

Thanks!

"Cannot load external plug-in file...".
I did everything according to the instructions, I think. renamed and replaced tbb.dll file. copied files from folder lib to folder with plugin.

[raymondtrace]

I believe there is a mistake in the instructions. You should not be copying anything from the "lib" folder. The "lib" folder does not contain the DLLs listed in the instructions. Copy the DLLs from the "bin" folder instead.

Here's a suggested revision for the instructions, with corrections in bold/red...

Extract these dynamic libraries (from the ....x64.vc14.windows\bin directory)
OpenImageDenoise.dll
tbb.dll
tbbmalloc.dll
in the same directory than the node plugin,

This worked for me.

Yes, thank you - now it's working.
I have done several tests to compare the work of the built-in GPU denoiser and the Denis plugin. On average, Denis's plug-in works slightly faster (1-10%) and produces cleaner results on open, slightly shaded surfaces. While the built-in denoiser on open surfaces leaves more noise (with blur), but it works better in areas where shadows lie.

I have not yet studied how to work with Albedo and Normal functions.

Yes, sorry I fixed the mispelled directory in the readme file,
you need only the dll files.

The raw buffer may be a "based" albedo for this input,
but i.e, if surface has transparency you may need to composite
with other buffers, or create a custom buffer.
Every kind of Normal buffer may work (screen or world)

Reminder: except beauty color each buffer used in the RenderBuffer node must be selected
in the Image Filter node editor panel)

I've observed the same on some basic tests (between the native and DP node filter CPU denoisers). I need to experiment more on various buffers.

you need to do a render with both denoisers off as well, for all people could know the image could be clean before denoising, so you need a base mark to compare the effect

[raymondtrace]

Here are some very crude example renders using default settings only on the final render buffer. There are a couple faults with this scene. It is unusually dark and there's no detailed geometry that can demonstrate if the noise removal excessively blurs those details.





I initially tested on a better lit client scene and got much better results. I should have tested on something else I could share.

Denis, maybe I am not looking into the right place, but I can't find any readme file in the archive (OpenImageDenoise_2018_x64.zip).

[Lito]

Same here, I just downloaded the zip and there is only one .p file inside. No .dll files or subdirectories.

[dpont]

Fixed, download again.

Would be nice to see this baby for LW2015 32bit��
