Interesting news! But the online sample looses sharpness and has a hue shift. Did you observe the same?

hm. I only checked the gallery. look at crytek sponza at 16spp. BCD would not be able to do anything there...
also, unlike nvidia denoiser, this runs on cpu...

You can actually test it, they have a standalone terminal application like the Declan Russel optix program.
https://github.com/OpenImageDenoise/oidn/releases
It's in the "bin" directory. The needed libraries are in "lib", so you will either have to set LD_LIBRARY_PATH to "lib" or copy them over. (this is for the Linux version, have not checked the Windows archive)

will check it out tomorrow. But, it also uses albedo and normal passes for detail preservation.... there is no albedo in luxcore :(

Here's a quick test.
I saved as EXR and used this as the only input, no albedo or normal AOV.
The standalone application is a bit of a pain to use because it only supports PFM images, so you have to convert everything back and forth.
And it only supports little endian PFM, not big endian. So your imagemagick line should be:

Code: Select all

convert noisy.exr -endian LSB noisy.pfm
Then you can feed noisy.pfm into the program.

Also note that this test is missing a ground truth image.

I'm on phone, but it looks like intels denoiser is way better. With extra passes it could be a killer feature not only for previews but for final frames too!

Looks great, I totally want this :!:
Maybe this works even on Bidir?

Well if we will have indirect and caustic caching you won't need bidir, would you? + this type of denoiser and rendertimes will be in minutes for complex scenes
