SpotLess - Temporal denoise

[Frank62]

Sorry, bad idea. Should rather be the opposite. Doubles are good for removedirting. Motion-compensated frames are of course less good.
So forget my proposal...

[StainlessS]

Maybe just try the temporal median filter that spotless uses.

RadT = ??? [int, try bout 2]
MedianBlurTemporal(radiusY=0,radiusU=0,radiusV=0,temporalradius=RadT)  # Temporal median blur only [not spatial]

If it is so static, it might work well.

[Frank62]

What exactly makes it more static than f. e. RemoveDirt?
To me it seems somehow more stepless, but how does it do this? "Blur" implicates some temporal interpolating, but it seems to be more than this.

[StainlessS]

Dont know but,
Here it is on Wiki:- http://avisynth.nl/index.php/MedianBlur2
And link (from wiki page) to a paper on it:- http://nomis80.org/ctmf.html

[Frank62]

Thanks, but it says nothing about the temporal part of filtering.

Arx1meD,
Perhaps you should create your own thread for your script function, also maybe give it another name other than Spotless2(),
as it does not function much at all like the Spotless filter.
I only tried this to see if it threw an error or not due to you having 2 [EDIT: formal] args named RadT,

AviSourcE("D:\parade.avi")
Spotless2()

However, caused access violation on line 33, ie the DeSpot line.

Suggest you create new thread, and correct/rename your script filter,
and post an example sample clip together with a working client script.
EDIT:

Function SpotLess2(clip c, int "RadT", int "Spot", bool "DeGrain", int "RadT", int "ThSAD", int "ThSAD2",
    \  int "pel", bool "chroma", int "BlkSz", Int "Olap", bool "tm", Bool "glob") {

also, it is not good practice to destroy compatibility by inserting new formal arguments before existing arguments ie your

 int "Spot", bool "DeGrain"

EDIT: Version Despot I was using was v3.6.3.0, there is a v3.6.3.1 here:- http://www.avisynth.nl/index.php/DeSpot
V3.6.3.1 does not cause access violation.

Strangely, it does not throw an error due to 2 different instances of the formal parameter "RadT", maybe a bit more checking needed in Avs+.

[Arx1meD]

Thank you StainlessS. I will fix the errors and create another thread.
I am using Avs+. When testing the script, I got no errors.

[StainlessS]

New Test [1.07beta] version of SpotLess, comments ?

Changed bBlur default from 0.0 [OFF] to 0.6, slower but should be considerably better on MC analysis.
Would it be preferable to remain at 0.0 faster.

Also, added DC [prefiltered detection clip], where supplied, bBlur prefiltering ignored and uses dc clip instead.

/*
    SpotLess v1.07Beta. temporal spot/noise remover, by StainlessS @ Doom9.   https://forum.doom9.org/showthread.php?t=181777
    Original idea from Didée post :-                                      https://forum.doom9.org/showthread.php?p=1402690#post1402690
    Req:- Pinterf MvTools2(), Pinterf Medianblur2() with MedianBlurTemporal rather than the MedianBlurT() from Didée post.
          With appropriate plugins, will be AVS+ colorspace and x64 compatible.
          Fine using Avs+ Prefetch() so long as current Pinterf plugins, and Frame Accurate source. RequestLinear() following the source filter might suffice as frame accurate source filter.

    NOT FOR cartoon/anime, live video only, sorry.

    v1.01, Remove RadT Max check. Add MSuper(hpad=16,vpad=16). Add BlkSz arg.
    v1.02, Add some stuff.
    v1.03, Frame size auto config of args removed (found instances where caused problems). Added Glob and bBlur args.
    v1.04, Script breaking changes, I guess is more flexible if can also set ThSAD, inserted ThSAD 3rd arg. RadT now default 1, was 2, dont over denoise unless requested.
    v1.05, Additional checks on args.
    v1.06, Glob Default true, Almost always better.
    v1.07Beta, bBlur Default changed from 0.0 OFF, to 0.6, slower but better for mc analysis. Maybe try 1.0 for HD to overcome HD 'gritiness'.
               Added dc arg, detect clip.

    SpotLess(clip c,int "RadT"=1,int "ThSAD"=10000,int "ThSAD2"=ThSAD,int "pel"=2,bool "chroma"=true, int "BlkSz"=8,Int "Olap"=BlkSz/2,
            \ bool "tm"=true,Bool "glob"=True,Float "bBlur"=0.6, clip "dc"=Undefined)

    RadT, 1 or more, Default 1. Removes Spots on up to RadT [Temporal Radius] consecutive frames.
        RadT > 2 will usually be overkill. Setting too high could possibly result in blurring.
        Each pixel in result frame is median pixel value of (2*RadT+1) motion compensated frames (including source, ie current_frame-RadT to current_frame+RadT).

    ThSAD, Default 10000=NEARLY OFF(ie ignore hardly any bad blocks), 0 < ThSAD < 16320(8*8*255). 8x8 block SAD threshold at radius 1 (ie at current_frame +- 1) [SAD, Sum of Absolute (pixelwise) Differences].
        ThSAD and ThSAD2 suggested absolute minimum of maybe about 400.
        ThSAD and ThSAD2 thresholds are based on 8 bit 8x8 block, irrespective of colorspace depth or BlkSz, max=8x8x255=16320, use same thresholds where High Bit Depth.
        In mvTools MCompensate(), when creating a compensated block the SAD between compensated block and the same original block in current_frame, the 8 bit SAD is measured and if
        greater than SAD threshold then that block is ignored and uses original block from current frame instead. [The compensated block is judged too different, so ignored & original block used instead
        in the result MCompensated frame].
        Where eg ThSAD=64, AVERAGE absolute single pixel difference threshold would be 64/(8*8)=1, so AVERAGE absolute pixel difference greater than 1 would ignore that mcompensated block and use the
        block from current frame in the resulting mcompensated frame instead. This example allows for all pixels in a 8x8 block to be different by 1, or a single pixel in 8x8 block to be different by 64,
        or some other mixture.
          A problem with above is, if a low ThSAD and current_frame block is mostly noise, so compensated blocks could be judged bad because they are too different to the bad noisey block, and the result
        block may/will be just as bad as the noisy source block. A possible solution to this problem is to have a higher SAD threshold and/or have a bigger BlkSize so that the number of bad source pixels
        after converting/scaling to as if an 8x8 block, will contain fewer bad noise pixels. So, SpotLess BlkSz arg would ideally maybe 4 or more times the area of the largest spots that you have, and a SAD
        threshold big enough so as to not ignore the block [ wild guess minimum SAD threshold for big spot sizes of (8x8x255)/4 = 4080 ].
        Where a complete source frame is bad, then maybe should have very high (eg 10000) SAD threshold, and BlkSz may not really matter too much.
          It is not the end of the world if some of the compensated blocks are ignored and swapped for the original current_frame block. Nor is it the end of the world if
        no blocks were ignored because of high SAD threshold. The final result pixel is median pixel value of (2*RadT+1) motion compensated blocks, so allowing for some mistakes by choosing the
        middle pixel value.
        I've just tested real bad double frame, full frame luma and chroma corruption, with below line:
            SpotLess(RadT=5,ThSAD=1000000,ThSAD2=1000000,pel=2,chroma=false,BlkSz=8,Olap=4,tm=false,glob=false,bBlur=0.0)
        And although both SAD thresholds of 1 million, are totally impossible and so no blocks could possibly be ignored and yet we still got pretty good results, all frames were fixed
        as we still had the temporal median filter to fall back on and pick the middle pixel value.

        From mvtools2 docs:
          ThSAD is SAD threshold for safe (dummy) compensation.
              If block SAD is above the thSAD, the block is bad, and we use source block instead of the compensated block. Default is 10000 (practically disabled).

    ThSAD2, Default ThSAD, 0 < ThSAD2 < 16320(8*8*255), Lower removes fewer spots, but less chance of blurring.
        ThSAD2 sets the SAD [Sum of Absolute Differences] threshold for most distant frame from current_frame at distance RadT, with those frames that are distances in-between 1 and RadT
        acquiring a SAD threshold linearly interpolated between the two.
        From mvtools2 docs:
          ThSAD2:
              Defines the SAD soft threshold for the furthest frames at current_frame +- RadT.
              The actual SAD threshold for each reference frame is a smooth interpolation between the original thSAD (close to the current frame)
              and thSAD2. Setting thSAD2 lower than thSAD allows large temporal radii and good compensation for low SAD blocks while reducing the global error and the
              risk of bluring when the result of MCompensate is passed to a temporal denoising filter.
        EDIT: Although I have said that SAD threshold being too high could result in blurred frames, that is really taken from above "risk of bluring" line from mvtools docs,
        however, that warning says "temporal denoising filter", which might suggest pixel averaging, whereas we are using pixel median. I'm not sure that blurring would be the result
        of having too high a SAD threshold.

    Pel,     Default 2. 1, 2, or 4. Maybe set 1 for HD+. (1=precision to pixel, 2=half pixel, 4=quarter pixel)

    Chroma,  Default True. MAnalyse chroma arg. If true, use chroma in block matching when creating vectors. Maybe use False if source B&W or color noise.

    BlkSz,   Default 8. MAnalyse BlkSize. Bigger blksz quicker and perhaps better for HD clips. [Info: current Pinterf MvTools allows for BlkSize=12, and overlap=6]

    OLap,    Default half BlkSz, Block overlap.

    Tm,      TrueMotion Default True. Some folk swear truemotion=false is better.

    Glob,    Default True (True v1.06, was same as Tm, true almost always better), Allow set MAnalyse(global) independently of TrueMotion.
             From MvTools2 docs for MAnalyse,
               global
                 Estimate global motion (at every level) and use it as an additional predictor.
                 Only pan shift is estimated (no zoom and rotation).
                 Use false to disable, use true to enable.

    bBlur,   Default 0.6. If used, Suggest about 0.6, where MAnalyse create vectors is performed on denoised (blurred) super clip
             for better motion analysis. Maybe try 1.0 for HD clip to counteract HD 'grittiness'. bBlur ignored if dc clip specified,
             If providing bBlur, then ALWAYS specify as named argument ie bBlur=bBlur, we will likely insert any additional MvTools args
             before bBlur to keep them together.

    dc,      Default UnDefined. If dc Specified, then must be same size and colorspace as source clip.
             If detection clip specified then bBlur prefilter arg is ignored, and analysis is performed on
             dc.MSuper() clip [ instead of c.Blur(bBlur).MSuper() ]. Allows to provide your own prefiltered clip.
             If providing dc clip, then ALWAYS specify as named argument ie dc=DC, we will likely insert any additional MvTools args
             before bBlur to keep them together.

[GMJCZP]

Hi TinMan, I wish you good luck with your script. The biggest challenge you are going to have is with anime, specifically with scenes with rain, because if the spot detection method is incorrect you will notice how the raindrops disappear before your eyes, KillerSpots was precisely tested exhaustively under these conditions

[StainlessS]

Hi GMJCZP, [I think I messaged you when I implemented Spotless, to let you know I extended your/didee script.]
I'm personally not bothered about anime, and said 'not for anime' in 1st or 2nd post, as uses RadT greater than 1, there is little
chance that any anime rain would survive RadT>=2.
If you aint tried it [SpotLess], give it a go, is almost magic with RadT>1, removes double spots, and even had it remove 4 consecutive BIG BIG BIG spots.
Glad to see you back, keep safe.

[Sharc]

SpotLess is perfect for my VHS sources. Thank you!

[StainlessS]

Fixed in post #16 [not the Spotless script]
Was

Prog = (UNSPOT_I)   ? Prog.SpotLess(Radt=RADT_P,thsad2=ThSAD2_P,blksz=BLKSZ_P,tm=Tm_P,bBlur=bBlur_P)  : Prog

Doing Babylon5 again [spent huge amount of time [hand edits] first time around).
But think I'll use TFM(pp=0) beforehand to get rid of Perverse Telecine [in some episodes], before using post #16 script.

Babylon5 [PAL version] Perverse Telecine mentioned here:- https://forum.doom9.org/showthread.p...72#post1785472

EDIT:
Episode 1 season 1 has some double frame spots [on progressive parts], so I thought I'de do it all again with spotless,
via the post #16 script, script is a bit slow [with doublerate output, which I'm doing this time].
I'm gettin about 60FPS with i7-8700 [so I guess maybe not that slow, but is only a bit faster than real time 50FPS output,
and 110 episodes, so is slow/tedious].

EDIT: "with doublerate output, which I'm doing this time"
OUTPUT=3 # 3=DblRate 50fps. Prog=Interpolate.
and TFM(pp=0) after AssumeTFF.

Are you still doing B5 then? I have done s1 ep1 a while back, removed all the dust, scratch, etc with dirt cleaner which was about 95% good. The rest I'd spotted during playback. Upsampled it to 1920x1048, fixed some colouring, sharpening etc.
Hell a lot better than my dvd for sure.

Onto ep2 - Soul Hunter. Can you read this link for me

https://forum.videohelp.com/threads/...vertical-lines

And possibly come up with a solution. Tried many software and can't clean it up. If you have the dvd then look at frame 13745 to 18634 (9mins 9 secs to 12:25) and you see those 3 static lines that appear in all scenes involving the non-regular casts.

I have minimised it using photoshop to create 3 vertical fixed mask and denoise to remove the bluish lines but there is a faint white line in parts left. Those scenes have slight band from WB bad attempted removal before dumping it onto the market. Those scenes looks too dark as if WB tried to reduce the visibility of the lines. Did some colour correction and looks good, just those pesky whitish lines.

Let me know if you have any solutions. Cheers.

[StainlessS]

OK, I found the lines, (although I did not originally even notice them in your sample file - I thought it must have been cleaned result).
Just tried my used script, and still there afterwards.

I personally have reached the conclusion that life is too short to be spending eons on such things,
do yourself a favour and live with them (look the other way when they show up on screen).

Wish I could give you a better answer, but I dont got one

EDIT:
I think this is about same as template script I used [I stopped mid Season 3, and am busy doing other stuff, continuing later].

I dont even bother with spots on interlaced sections, they're naff/indistinct anyways and dont need more over processing.

I pointed out in your thread over in the Videohelp format, that eliminating vertical lines is a tough challenge. However, unlike film scratches which are virtually impossible to remove, you can remove your scratches. However, the problem will be the inevitable blur that will result from blending pixels from the adjacent area. I suggested using the VirtualDub Delogo plugin, but I'm sure there are better choices.

Spotless is almost certainly the wrong tool because it is looking for differences between frames: when a spot shows up for just one frame, it is removed. Since your lines do not change from frame-to-frame, there are no difference vectors, and Spotless likely won't do anything.

Some of the experts on using AVISynth masking may have some more clever ideas. You might start your own thread here and see what you get.

I think he was just asking me because I said I was doin the same series, just in case I did something clever with those near invisible lines.
110 eps is one helluva lot of viewing never mind examining and special casing for those lines.
If you're getting big bucks for a total remaster of original source, then is maybe sane, otherwise not.

[StainlessS]

John or coolgit or anybody really,

Avisource("SH_2_secs.avi.avi")  # Did not have codec for FOURCC, redid in ffmpeg to UT_Video so AVI.AVI
ConvertToYV24
O=Last

# Intention: Single pixel width, vertical line/scratch reduction.
GeneralConvolution(0, "
1 0 1  
2 4 2  
1 0 1
")

StackVertical(O,Last)

I thought above might work-ish, just made up the matrix string on gut feelin' no idea if is any kind of standard matrix
but it does seem to make some difference.
[I cant really see it properley lousy eyes and I'm on a smaller monitor, main machine busy doing something else, and not
got Avs stuff installed on it (actually messin with linux install on it)].

Can you test out above and see if it is of any worth at all [and if it blurs much].

Only my guess work and I got almost zero experience of same, so might be rubbish.

EDIT: Could be applied to frames/ranges using clipclop. Gotta be faster/less-user-interaction than delogo or descratch or whatever.

EDIT: In VDub2 at 200%, I'de say reduces scratch to about 50% visiblility, not perfect but does not seem to create additional artefacts
that I can see.

Is your template above for MeGui only?

The GeneralConvolution didn't do anything. I don't understand it either. Vdub2 has it and I've never used it. All it did what change the output to black with very faint movements.

What i am looking for, dunno if it can work, it a simple replace bad pixel type plugin. The way i see it would work like this.

Instruct start hor pixel(say 300) and end hor pixel (305) and full vert length - like masking and only work in this area and nowhere else.
Pixel 300 to 305 are considered bad.
Lets focus on 5 main colours. BWRGb. | = start and end mask boundary.


Small example

Good bad good
pixels pixels pixels
BBBB|WbbbWW|BBBB
BBBB|WWbbbW|BBBB
GGGG|WWbbbW|RRRR
GGGG|WbbbWW|RRRR

would become by using previous good hor pixel(299) and hor pixel(306) on both side alternately to overwrite the bad pixels

BBBB|BBBBBB|BBBB
BBBB|BBBBBB|BBBB
GGGG|GGGRRR|RRRR
GGGG|GGGRRR|RRRR

The above looks simple enough to me. No blurring, no band lines, no random guessing based on fancy algorithms, etc.

How hard can it be?

I know but i have been making headway using photoshop and topaz denoise.

However, unlike film scratches which are virtually impossible to remove, you can remove your scratches. However, the problem will be the inevitable blur that will result from blending pixels from the adjacent area. I suggested using the VirtualDub Delogo plugin, but I'm sure there are better choices.

Topaz denoise removed source file faint bands and also removed blur which was bloody useful. It actually removed the grain inside the whites of the eyes making the eyes look visibly better. Faint white lines about 3/4 pixel width remains. I had an idea how to remove bad pixels and replace them with good pixels in my last post above. Is it feasible with avisynth?

Some of the experts on using AVISynth masking may have some more clever ideas. You might start your own thread here and see what you get.

This what i need, masking. I want to be able to focus on the 3 lines and nothing else. Hence why i am using photoshop.
