BM3D (VapourSynth) versus MVTools

DJATOM · 4th July 2021, 18:10

CUDA based BM3D (V-BM3D) is fast enough on decent GPU and probably faster than mvtools2 with small temporal radius. You might want to consider using it as faster denoising backend.
Some numbers if you interested:
1080p, radius=3, fast=True - ~21.85 fps
1080p, radius=3, fast=False - ~14.17 fps
1080p, radius=2, fast=True - ~38.93 fps
1080p, radius=2, fast=False - ~19.69 fps
1080p, radius=1, fast=True - ~63.21 fps
1080p, radius=1, fast=False - ~31.49 fps
1080p, radius=0, fast=True - ~159.75 fps (that's a spatial mode)
1080p, radius=0, fast=False - ~79.24 fps (that's also a spatial mode)
"fast" option squeezes more fps with the same quality at expense of flooding PCIe lanes, probably my card can preform better, but due to SSD attached to CPU lanes it works at x8 mode (still enough for me).

ahh finally some numbers for bm3dcuda. Could you also post some numbers for the bm3dCPU version? I wonder how big the speed gap is.

DJATOM · 4th July 2021, 19:41

radius=0 - ~114.46 fps
radius=1 - ~65.87 fps
radius=2 - ~46.11 fps
radius=3 - ~36.03 fps
radius=4 - ~29.26 fps
I'm measuring with 12 cores CPU and overclocked RAM (yet no turbo boost enabled).

Didn't expect that. It's even faster than your 2070. I guess a ~8 cores cpu could be about the same speed as the 2070 then.

Thanks for your suggestion, I did not know that BM3D had a CUDA version. Where can I find a Windows build, better with HBD support?

However, there are a few CUDA denoiser around already. What we need is a MVTool on CUDA or OpenCL.

Scroll to version 2.1 for cuda version.

Thanks but it is for VS not AVS+.

kedautinh12 · 5th July 2021, 08:34

In the present, BM3D only in VS

WolframRhodium · 5th July 2021, 09:22

The numbers from DJATOM looks interesting.

The GPU performance aligns well with the estimation that

Code:

fps * (2 * radius + 1) ≈ constant

, since the calculation is dominated by block matching.

The CPU performance is unexpected to me. Maybe the cache plays a nontrivial role.

Anyway, I have no experience in writing an AVS+ plugin. Will take a look if people are interested.

kedautinh12 · 5th July 2021, 09:31

Yeah, i'm waiting many years for avs+ ver

you can make the plugin work in both https://github.com/HomeOfAviSynthPlu...on/neo_DFTTest (this is backport of vs DFTTest and now it's work on both)

Thanks, I am aware of the DualSynth implementation. I need to read more about the parallelism mechanism of AVS+, thought.

+1 ... definitely some interest here.

Dogway · 8th July 2021, 09:27

Obviously super interested in this. I think it can easily double current scripts speed that make use of mvtools. Probably for implementation reference you can check source of AVS+ 3.7.1 CUDA.

real.finder · 22nd July 2021, 05:42

WolframRhodium, any news about avs+ port?

@Moderators, can you move BM3D posts to new thread?

Moved. It is ok now?

Yes. It's fine. Thanks

I'm sorry about being lazy on avs+ port... Will consider it this weekend.

Dogway · 22nd July 2021, 17:14

I think OP was replying to my post:

Thank you WolframRhodium, it would actually be an achievement and a revolution for AVS since mvtools is the major bottleneck in most scripts.

I'm confused, so the 3900x is faster than the RTX 2070??
