KNLMeansCL: OpenCL NLMeans de-noising algorithm [2018-01-29]

[Khanattila]

@sl1pkn07
Yes, quite similar to that sound in this video. The strange thing is that it is the first time I hear that sound. I had my graphics card in long sessions rendering with Blender 3D/CUDA and this sound does not appear at all (it's a pretty quiet card). Perhaps bad optimized for OpenCL?

I'm testing this script with a set of PNG (script in message #234 and png images in message #241):
http://forum.doom9.org/showthread.php?t=171207&page=12

I run:
vspipe --y4m script.vpy - | ffmpeg -i pipe: -vcodec libx264 -crf 10 encoded.mkv

My nvidia card starts making these weird sounds, but I do not get messages in the terminal indicating that the script is working and the file "encoded.mkv" is never written to disk (I cancel at 15 seconds, I do not like that sound at all).

Edit:
Ok, I tried again and in Blender (CUDA or OpenCL) also makes some of that sound, but much less (I had to open the Case cover and close to it to hear the sound). Perhaps this plugin in vapoursynth is entering some kind of loop with OpenCL and my card?

I do not know your system, but KNLMeansCL is well optimized.
It is not perfect, but it is well optimized.

[YAFU]

If you are in this thread, you probably want to try KNLMeansCL.

Yeah, the script we were talking used KNLMeansCL (I guess, I do not know much about these things). What happens is that I have no idea on how to create these scripts. What I was wondering if you could recommend me other script that uses KNLMeansCL with which to reduce that kind of noise generated by Blender 3D.

I searched through this thread, and the truth is that I understand almost nothing about the technical things that are mentioned here.

[feisty2]

the script is TOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOoooooooooooooooooooooooooooooooooooooooooo........... slow

http://wstaw.org/m/2015/09/04/Screenshot_20150904_220515.png

/me pats feisty2 XD

now that dct=5-10 works, it could be even slower, and yet I ain't gotten dfttest to join the game to do the low frequency denoising

Also something is wrong somewhere with that script because... pink output, but yeah, what you experienced was your computer trying to die.
I had tested that script before I posted it out, so it should work, tho I only did my test on a GRAYS clip

then forget about mvtools
this simple little script is still kind of high quality


import vapoursynth as vs
core = vs.get_core()
clp = core.imwri.Read('png-50/%04d.png', firstnum=1, alpha=False)
clp = core.fmtc.bitdepth (clp, bits=32, fulls=True, fulld=True, flt=True)
clp = core.knlm.KNLMeansCL(clp, d=3, a=12, s=4, h=3.2)
clp.set_output ()

[kalehrl]

How to install this KNLMeansCL?
Where the put the files from the archive?
I put KNLMeansCL.dll in avisynth plugins folder and the script gives me this error:
"There is no function named KNLMeansCL"

@feisty2, I tried this little script. vsedit does not show any problem when I choose "Check script". But when I choose "Preview" vsedit closes and I get this error in linux terminal:

I get the same error with vspipe:

You have to set the -fopenmp as a link option.
Or use the configure attachment.

use_D3D: true/false (default: false)

Use D3D operation. This should be set only if you receive a decoder creation error when it is not set. Some versions of the Nvidia driver require D3D operation.
Always first try with use_D3D set to false and set it to true only if a decoder creation error is encountered.

Try it.

Sorry, I searched on google about that and I'm a little lost here.
Is that when I compile?

I compiled KNLMeansCL with:
./configure
make
sudo make install

It's correct. Your operating system?

I do not know if this is related, but I have installed a package called "libgomp1" v4.8.4 containing "/usr/lib/x86_64-linux-gnu/libgomp.so.1" and "/usr/lib/x86_64-linux-gnu/libgomp.so.1.0.0"

I'm currently running KNLMeans on a very noisy 1080p video and it's running very slowly with the GPU topping at 100%. I have a dual-graphics with Intel HD 4000 and Radeon 7670M, and you're using the Intel HD by default.

You say I have to change the default OpenCL device for my system? How do I do that?

[MysteryX]

Actually, right now KNLMeans is running on the Intel HD 4000 while InterFrame is running on the Radeon 7670M, and both are capped at 100%, so perhaps it's best this way.

0.6.2 works for me.

[Sparktank]

Tried. Error: Failed to find CUDA D3D device.

Tried re-install?
Advanced -> "clean" install.

[Sparktank]

NLMeans degrades to something like "Motion Flow" (pixel wise motion compensation) by setting A=0 (spatial processing disabled)
and the jerky lines are just common motion flow artifacts
solution: enable spatial processing, pick an A value greater than 0

:cool:Noted!
I don't play with much parameters for this, aside from "h".
But since all the updates, I decided to play a little more with different settings.

For "unknown" reasons, Intel driver set itself as default device.
Now I not find the publication but I will change the system of the plugin soon.

[YAFU]

@Khanattila, Thanks for your time.
I have these packages installed.

I've done more tests, I reinstalled Intel OpenCL. I am using this script:
import vapoursynth as vs
core = vs.get_core()

clp = core.imwri.Read('/media/TEMPORAL/images_16/%04d.png', firstnum=1, alpha=False)
clp = core.fmtc.bitdepth (clp, bits=32, fulls=True, fulld=True, flt=True)
clp = core.knlm.KNLMeansCL(clp, d=3, a=12, s=4, h=6.4, device_type="CPU")
clp.set_output ()


With "GPU" I keep getting the same error I had told you in message #360. With "CPU" Check Script is ok and shows no errors (like GPU), but with "Preview" sometimes vsedit is closed with the same error that shows "GPU" and sometimes shows the next message:
Failed to evaluate the script:
Python exception: No attribute with the name imwri exists. Did you mistype a plugin namespace?
Traceback (most recent call last):
File "vapoursynth.pyx", line 1469, in vapoursynth.vpy_evaluateScript (src/cython/vapoursynth.c:23703)
File "/media/TEMPORAL/script.vpy", line 9, in <module>
clp = core.imwri.Read('/media/TEMPORAL/images_16/%04d.png', firstnum=1, alpha=False)

AttributeError: No attribute with the name imwri exists. Did you mistype a plugin namespace?


That's weird, because I have "imwri" installed and it works well with the other script I mentioned in mv tools thread.
Have you tried this script with images? Are this script working on your computer?

Then I tried with videos using this script:
import vapoursynth as vs
core = vs.get_core()

##ffmpeg with ffms2
core.std.LoadPlugin('/usr/lib/x86_64-linux-gnu/libffms2.so.3')
clp = core.ffms2.Source(source='/media/TEMPORAL/test.mp4')

clp = core.knlm.KNLMeansCL(clp, d=3, a=12, s=4, h=6.4, device_type="GPU")
clp.set_output ()

This is somewhat slow (0.6 fps in GPU), but KNLMeansCL is working well with videos both, CPU and GPU.


So, do you have any idea why it does not work with images and "imwri"?

[sl1pkn07]

I get


vspipe: symbol lookup error: /usr/lib/vapoursynth/libknlmeanscl.so: undefined symbol: GOMP_parallel

Same error then.

With these 16 bit png, How could I create some kind of lossless video keeping the 16-bit color depth? Perhaps with ffmpeg, but how?
This I say for apply to the obtained video the KNLMeansCL script for videos.

you can use ffv1 in ffmpeg, which supports many configurations including 16bits/channel

eg it might look something like this



ffmpeg -r 24 -i "media/TEMPORAL/images_16/%04d.png" -start_number 0 -c:v ffv1 -an ffv1_output.avi

Have you tried this script with images? Are this script working on your computer?

Might be worth running under valgrind and/or gdb to see if anything strange pops out, especially if you can rebuild everything as debug. There's no good reason imwri should fail to load unless something weird is going on.

Use device_id in the v0.6.3 :sly:

[sl1pkn07]

yep, but have another little trouble with 0.6.3

when try to use with vsedit, when run in a first time, the preview window (F5) works ok, but when close the preview window, and change anything in the the script (or just reload the preview without changes), vsedit it hangs/freezes.

only happens when try to load the preview in a second time,

tested with CPU, GPU, ALL, DEFAULT (including setting the device_id)

[YAFU]

@poisondeathray, thanks for that command.
@foxyshadis, if I comment the line containing "core.fmtc.bitdepth" and add the line suggested by sl1pkn07, the script works. Thanks sl1pkn07.
@Khanattila, Nice speed improvement on my system with 0.6.3. With the value "a=12" in the script, before 0.6 fps. Now 6 fps! Now I can do some testings with more comfort.
The only problem that remains, if I use a greater than 4 value in "s", it does not work and I get the message "pipe:: Invalid data found when processing input". Is 4 the maximum value that can take "s"?

Yes, for hardware performance limitations.
For bigger s I need to implement a transpose kernel.
But original Non-local means use s=3, it is not a great limitation.

You have 0.6 fps when using the CPU instead of the GPU.

[YAFU]

No no, I was getting 0.6 with GPU. With CPU even less. Now CPU=0.5 fps and GPU=6 fps. But for that there is no doubt I just compile and install 0.6.2 again:
(GPU: GTX 960; CPU: i7 3770)
0.6.2:
CPU= wait a minute and it does not even start...
GPU= 0.6 fps

0.6.3:
CPU= 0.5 fps
GPU= 6 fps

I do not know what has changed in the code of the new version.

[sl1pkn07]

:script: :logfile:

any script who uses knlmeanscl? XD

[feisty2]

I do, but it works just fine on windows

[tormento]

I put my previous Win8.1_x64 booting disk in my PC. Same HW configuration, same encoding plugins, etc. Everything works as it should.

So, I have done some research with Google and I have found the following in the Blender forum:

Blender uses CUDA 6.5, but it does not support win10 officially.
CUDA Toolkit 6.5
win10 should be supported by CUDA7.5RC.
nVidia Developer Zone

It does not think it's strange even if an error occurs in my opinion.

If any has ideas on how to solve this problem, please give hint.

[Khanattila]

Apparently the parameter "d" loses its functionality with 0.6.3 in VapourSynth. Check it with info=True. No matter what value you set, "D" is always displaying 1. That's the reason why YAFU got false speed improvement.

Here's what happens to have little experience with vapoursynth. :rolleyes:

Simply use the following command and repeat it a few times.
vspipe -p foo.vpy NUL

OS: Win10 Pro x64
GPU: GeForce GTX 660
Driver: 355.82

Confirmed.

Seems like vspipe does not like openmp.

I put my previous Win8.1_x64 booting disk in my PC. Same HW configuration, same encoding plugins, etc. Everything works as it should.

So, I have done some research with Google and I have found the following in the Blender forum:



If any has ideas on how to solve this problem, please give hint.

try with the new cuda released today https://developer.nvidia.com/cuda-toolkit

DGDecNV has to be rebuilt with CUDA 7.5, but even then there is no guarantee. It's just something to try. Sadly I can't say when I would have time to do this. Also, CUDA 7.5 will lose the compute sm_1x cards, such as the GT 220. nVidia does not have a solution for this problem, and I'm not keen to maintain multiple versions. I could go back to SW for the DGIndexNV display code and ditch CUDA (not CUVID!) but I'm not keen on that either. :(

Try it again with r28 test 2. It may work. Or maybe not...

I'll try, alternatively I could use some SIMD instructions but I do not have much experience.
