Soothe() - small helper function for sharpening with less temporal jitter - Page 3

Pookie · 24th November 2005, 08:47

I thought it was my source and choice of codec.

iceborne · 1st February 2006, 05:00

i keep on getting washed out color whenever i applied this script:

Code:

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\mt_MaskTools.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\removegrainsse2.dll")
LoadPlugin("C:\Program Files\DGMPGDec\dgdecode.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\UnDot.dll")

mpeg2source("e:\dvd\divergence.d2v")

Telecide(guide=1).Decimate()

crop(4,60,-4,-60)

trim(5000,10000)


dull   = last
sharp  = dull.LimitedSharpenfaster( smode=4, dest_x=720, dest_y=368 )

Soothe( sharp, dull, 20 )

undot()

but if i leave out the resizing parameter
"dest_x=720, dest_y=368 ",
everything's good.

can anyone tell me what's wrong with my script?

foxyshadis · 1st February 2006, 05:32

Heh, I thought it was LSFaster for a few, until I noticed that you never resized dull. Pick a good scene with very sharply defined colors, and you'll notice the chroma will bleed horribly, since it gets copied from the second argument, not the first. Lesson: Always remember to resize both clips.

iceborne · 1st February 2006, 05:48

good man!

here's my new script

Code:

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\mt_MaskTools.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\removegrainsse2.dll")
LoadPlugin("C:\Program Files\DGMPGDec\dgdecode.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\UnDot.dll")

mpeg2source("e:\dvd\divergence.d2v")

Telecide(guide=1).Decimate()

crop(4,60,-4,-60)

LanczosResize(720,368)



dull   = last
sharp  = dull.LimitedSharpenfaster( smode=4, dest_x=720, dest_y=368 )

Soothe( sharp, dull, 24 )

undot()

trim(5000,10000)

btw, does it matter where i put undot()?

Mug Funky · 1st February 2006, 06:41

try:

Code:

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\mt_MaskTools.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\removegrainsse2.dll")
LoadPlugin("C:\Program Files\DGMPGDec\dgdecode.dll")

dull   = last.LanczosResize(720,368)
sharp  = dull.LimitedSharpenfaster( smode=4, dest_x=720, dest_y=368 )

Soothe( sharp, dull, 24 )

undot()

trim(5000,10000)

iceborne · 2nd February 2006, 04:39

thanhs guy. another question do you think sooth(sharp, dull, 24) is too low? or should i raise it to make the image sharper

foxyshadis · 12th February 2006, 01:46

In case anyone is feeling the burn and needs for speed, masktools 2:

Code:

function Soothe(clip sharp, clip orig, int "keep")
{
Assert(sharp.width == orig.width && sharp.height == orig.height,
 \  "Soothe: clip dimentions must match!")
keep  = default(keep, 24)
keep  = (keep>100) ? 100 : (keep<0) ? 0 : keep
KP    = string(keep)
diff  = mt_makediff(orig,sharp)
diff2 = diff.temporalsoften(1,255,0,32,2)
diff3 = mt_lutxy(diff,diff2,  "x 128 - y 128 - * 0 < x 128 - 100 / "  + KP 
 \                           + " * 128 + x 128 - abs y 128 - abs > x " + KP 
 \                           + " * y 100 " + KP + " - * + 100 / x ? ?")
return( mt_makediff(orig,diff3,chroma="copy first") )
}

[edit: Added a check for dimentions, since that's the most common misuse.

Also Didée TS suggestion.]
[edit2: Added both to wiki: http://www.avisynth.org/mediawiki/Soothe ]

Didée · 12th February 2006, 02:33

Even faster:

>> diff2 = diff.temporalsoften(1,255,0,32,2)

'cause here, chroma isn't interesting anyways, and TS runs faster when not having to also process the UV planes ...

iceborne · 12th February 2006, 06:03

cool, will try on next encode.

diazlaz · 12th April 2006, 14:11

Is it possible to get the soothe function to work, when a frame is being resized by LS? Example, currently have a video that is sized at 352,480, and using LimitedSharpenFaster(ss_x=1.2,ss_y=1.2,dest_x=704,dest_y=480,Smode=4,soft=24) to resize it to 704x480, when soothe runs, it errors with:

YV12LUTxy: Clip size must be the same.

Code:

function Soothe(clip sharp, clip orig, int "keep")
{
keep  = default(keep, 24)
keep  = (keep>100) ? 100 : (keep<0) ? 0 : keep
KP    = string(keep)
diff  = yv12lutxy(orig,sharp,"x y - 128 +", U=1,V=1)
diff2 = diff.temporalsoften(1,255,255,32,2)
diff3 = yv12lutxy(diff,diff2,  "x 128 - y 128 - * 0 < x 128 - 100 / "  + KP 
 \                           + " * 128 + x 128 - abs y 128 - abs > x " + KP 
 \                           + " * y 100 " + KP + " - * + 100 / x ? ?",  U=1,V=1)
return( yv12lutxy(orig,diff3,"x y 128 - -",U=2,V=2) )
}

Thanks,
Laz.

See Mug Funky's last post, on this page. Also consider using the version I posted.

Oline 61 · 15th April 2006, 23:37

The output of this script is awesome, but it is extraordinarily slow. Like running pixiedust on a 4096x1920 image. Huffyuv can encode it at ~1.5 fps. Can anyone recommend a way to speed it up?

Code:

MPEG2Source("VTS_06_1.d2v",cpu2="ooooxx")

Telecide(guide=1,post=1,back=1)

Decimate()

Crop(2,56,716,362)

LanczosResize(1280,544)
RemoveGrain(mode=1)
dull=fft3dfilter(sigma=1.5)

sharp=LimitedSharpen(dull,
	\	ss_x=1.5, 		ss_y=1.5,
	\	dest_x=1280, 		dest_y=544,
	\	Smode=3, 		strength=115,
	\	Lmode=3, 		edgemode=1)

Soothe(sharp,dull)

krieger2005 · 16th April 2006, 19:46

@Oline 61: Don't use fft3dfilter. If the speed-improvement is not enought don't use limitedsharpen... and so on

Oline 61 · 16th April 2006, 20:59

Without fft3dfilter there is no denoising. The output looks horrible because half of what is being sharpened is film grain.
I have tried putting fft3dfilter before the resize, and I think it might just be fast enough that way.

Code:

height=1280
width=544

MPEG2Source("VTS_06_1.d2v",cpu2="ooooxx")

Telecide(guide=1,post=1,back=1)

Decimate()

Crop(2,56,716,362)

in=fft3dfilter(sigma=1.5)

dull=LanczosResize(in,height,width)

sharp=LimitedSharpen(in,
	\	ss_x=1.5, 		ss_y=1.5,
	\	dest_x=height, 		dest_y=width,
	\	Smode=3, 		strength=115,
	\	Lmode=1, 		edgemode=1)

Soothe(sharp,dull,32)

foxyshadis · 17th April 2006, 02:53

Well, ft3d isn't the only denoiser; for similar results you might try a degrainmedian (or two). Or possibly mipsmooth, but that's harder to control.

Oline 61 · 17th April 2006, 04:58

DegrainMedian doesn't do all of the things I need. Removing grain is great, but it doesn't clean up the compression artifacts from the DVD like fft3dfilter does. I've got it up to about 2.6 fps for a turbo first pass. That is acceptable. Here is the script:

Code:

SetMemoryMax(768)
width=1280
height=544

MPEG2Source("VTS_06_1.d2v",cpu2="ooooxx")

Telecide(guide=1,post=1,back=1)

Decimate()

Crop(2,56,716,362)

in=fft3dfilter(sigma=1.5)

dull=BicubicResize(in,width,height)

sharp=LimitedSharpen(in,
	\	ss_x=1.5, 		ss_y=1.5,
	\	dest_x=width, 		dest_y=height,
	\	Smode=3, 		strength=100,
	\	Lmode=1, 		edgemode=1)

Soothe(sharp,dull)

EDIT: I'ma give LimitedSharpenFaster() a shot too.

audioslave · 5th June 2006, 23:59

I'm getting an error when using Soothe(). VDub says:

Script error: There is no function named "yv12lutxy".

What am I missing?

My script

Code:

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\LimitedSupport_09Jan06B.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\mt_masktools.dll")
Import("C:\Program Files\AviSynth 2.5\plugins\LRemoveDust.avsi")
Import("C:\Program Files\AviSynth 2.5\plugins\LimitedSharpenFaster.avsi")
Import("C:\Program Files\AviSynth 2.5\plugins\Soothe.avsi")

Mpeg2Source("D:\Hea\Video\DVD\Temp\Temp.d2v")

LRemoveDust_YV12(17,2)
Crop(6,78,710,420)

dull  = last.LanczosResize(704,416)
sharp = dull.LimitedSharpenFaster(dest_x=704,dest_y=416)

Soothe(sharp,dull,20)

Addborders(0,80,0,80)

audioslave · 6th June 2006, 00:12

I solved it. I didn't have MaskTools in my plugin directory...

HeadBangeR77 · 20th January 2007, 06:47

I'm just thinking while writing

If we resize, we can't write like e.g.:

dull = last
sharp = dull.LimitedSharpenFaster(dest_x=720,dest_y=304)

provided we haven't resized (to our destination resolution) before. That's the mistake iceborne made above in his first script. Then the comparison clip /background (dull) would have a different resolution than the sharpened clip, and the whole function didn't make sense. However, if we write ...

dull = last.LanczosResize(720,304)

than we don't have to specify the resolution arguments in LSF, do we?! I mean sharp = dull + LSF, and dull has already been resized just one line above. So we can write afterwards ...

sharp = dull.LimitedSharpenFaster() ?

How blind & stupid have I been! (bangs his head against the wall

) If the above is right, then LSF has the destination resolution, instead of the source resolution, as an input. That changes the supersampling effect, though the function's arguments don't change, and thus the sharpening strength too. Could anyone confirm /deny the above?

If that's true, I've spent all my day just in vain, encoding samples I didn't actually want to encode.

It would rather not matter, if I was downsizing a bit, like in the above examples, but I'm upsizing atm, and that changes a lot ...

Didée · 20th January 2007, 07:31

Code:

# how to soothe LimitedSharpen when LS is set up to change resolution

dx = your_target_width
dy = your_target_height

base = last.LanczosResize( dx, dy )
shrp = last.LimitedSharpen( dest_x = dx, dest_y = dy )

shrp.Soothe(base)
