LSharpAAF - AntiAliasing Combo

[Leinad4Mind]

Another AntiAliasing Script. :devil: It's more a combo... a combination of all antialiasing I know. :)

And it has some Extras like FastLineDarkenMOD, Presharpening, Postsharpening and Postsmoothing. :rolleyes:

It's very alike SharpAAMCmod... :search:

It contains: Sangnom, EEDI2, maa, daa, ediaa, aaa, ssa, splinaa, supaa, naa, shaarp, aaf, nnedi, nnedi2 and antialiasing :eek:

:script: Okay... I will post it... Here is the Code:

# LSharpAAF() by Leinad4Mind
# v1.50 updated in 2011-12-06
# Requirements: awarpsharp2; EEDI2.dll; FastLineDarkenMOD.avsi; LSFmod.v1.9.avsi; MaskTools.dll; mt_masktools-26.dll; mvtools.dll;
# nnedi2.dll; RemoveGrain*.dll; Repair*.dll; SangNom.dll; UnFilter.dll
# * HD; HDS; S; SSE2; SSE3; T; TSSE2; TSSE3
#
# All AA Scripts are in this script, so there are no need to download them separately; Except some of them that you can find in AnimeIVTC, as maa, daa.
#
# This is an Anti-Aliasing Combo with some Extras like FastLineDarkenMOD, Presharpening, Postsharpening and Postsmoothing

Here is all the require dll or extra functions: http://www.megaupload.com/?d=HQ7NLMW0

If u want to test it. Or improve the code, you're welcome :thanks:

[Frank K Abbott]

So this is an all-in-one anti-aliasing solution script? And how does it compare to other anti-aliasing methods that have been out?

[Leinad4Mind]

Well, it has 5 new methods: splinaa, supaa, naa, shaarp and aaf. And it's too an denoiser. You can apply sharpening and it has the LSFMod included to sharp and a line darkening to darken the lines as u wish.
And this AIO includes SAA by soulhunter and others antialiasing by didée that can be lost in some pages of doom9. So, this is good for everyone to not forget about the good AA we already have.

And I think it can be helpful. Because an AIO is always good. xD

Best Regards.

[markanini]

Cool, all AA functions/filters in place. :)

[osgZach]

Damn, if only we could get x64 version of all the required plugins

@Leinad4Mind.

I made my script and it works on VirtualDub and MeGui but unfortunately there has no effects in my video... :confused:
There has still a lot of aliasing... :eek:

unfortunately there has no effects in my video
Medicine doesn't help when it's just lying in the shelf. You need to ingest it.

Wrong:
1.) Have a clip
2.) Define a function
some_clip

function foo(clip c, param p) { blablabla }

This does nothing. The "function" statement does only create a function. After a function has been defined, it still has to be used.


Correct:
1.) Define a function
2.) Have a clip
3.) Use function on the clip

function foo(clip c, param p) { blablabla }

some_clip

foo()

[thanhtu5013]

OK.
I understand what you say Didée.

So I have to import the script of Leinad4Mind at first.
then adding my video source (AVISOURCE("C:\...")).

But the last step I don't understand...
I have really to write "foo()" at last ?

[Didée]

No. "Foo" is frequently used as a placeholder for "[use whatever name does fit here]".

So, instead of "foo()", you would call

either

LSharpAAF()

or

ediaa()

or

daa()

or

saa()

or

AAA()

or

antialias()

or

splinaa()

or

supaa()

or

naa()

or

shaarp()

[thanhtu5013]

Thanks a lot Didée. :)

I tried all functions. Every of them works except "antialias()".
"ediaa()" & "saa()" give me the best results.

Unfortunately, I still have a bit of aliasing.

Does it possible to make antialiasing filter works stronger ?
( Maybe it could make my video blurrer but anyway I want to try and I'll take a decision later. )

Sorry if I ask stupid questions. :p
I'm a noobs with Avisynth. :helpful:

[Great Dragon]

thanhtu5013, why don't you try an in-game AA option? I'm sure it's more powerful that AA-scripts for Avisynth.
Leinad4Mind, is it any benefits to SharpAAMCmod?

[cretindesalpes]

Does it possible to make antialiasing filter works stronger ?

You can run it multiple times. For example, in the following script you can select the strength for horizontal and vertical antialiasing. Set strh and strv between 0 and 3, over this value there is not much improvement and it generates artifacts.

Is it wise to believe that needi2 and eedi2 are the most effective for AA or could SangNom and unfilter serve as acomplement?

Because if I activate AA when I'm capturing during my plays, the framerate fall a lot.
( Under 9-10 fps so it's not possible to make a video )

I prefer playing without and apply a one through AviSynth.

These antialiasing techniques (using edge-directed interpolation) focus on smoothing lines and connecting them. They cannot improve Moiré patterns, they make them even worse because the ghost lines become real.

Your pseudo sounds french, you're french like me, right ? :p
Saperlipopette, je suis démasqué !

[thanhtu5013]

I have a last question.

Does it possible to make nnedi2 filter more efficient except changing strength values ?

With strh=2 and strv=2, the filter works fine but there has still a bit of aliasing.
It works like a 2x Antialiasing. I'm looking for something like 4x or 8x antialiasing.
Changing strh and strv values doesn't modify anything about that.

@cretindesalpes

Ton filtre marche très bien mais il y'a encore un peu de crénelage.
Changer les valeurs de strh et strv jouent sur le floutage ou le détail mais ne résout pas mon problème.
Peux tu me dire comment je dois modifier mon script pour qu'il applique un Antialiasing 4x ou 8x (si tu joues aux jeux, tu comprends ce que je veux dire) ?

[2Bdecided]

Here's an image I'm trying to improve:

Use TinEye if you can't remember where you got it from.

(sorry if that's a stupid suggestion, but you're never going to get the guitar strings on the neck to look right from that source - the aliasing is too bad).

Nice idea, and a great resource.

I kind of miss some documentation of the different AA types, with slowness and quality comparison.

I ran some tests myself on a avs script im working on for a anime dvd rip.

There is alot of others filters also in this script, but here is some fps and cpu data on a 720x480 source. Encode was directly with x264.exe on a i7 860 with disabled HT:

maa fps: 4,9 | cpu: 30%
ediaa fps: 4.6 | cpu: 99%
aaa fps: 5,7 | cpu: 40%
antialiasing fps: 5,6 | cpu: 40%
splinaa fps: 6,0 | cpu: 35%
supaa fps: 2,2 | cpu: 60%
naa fps: 1,9 | cpu: 75%
shaarp fps: 4,2 | cpu: 55%


(the FPS and CPU load is average over 5min)

[Leinad4Mind]

Thanks mastrboy. Hope you guys like it. ^^

I have update today the script with 1 more GOOD antialiasing: "aaf". The new avsi is attach.

Best Regards

[Leinad4Mind]

New version of it. I've found a bug in Presharpening, I've forget to finish it xD. And I've improve the code a lot ^^.

I've added (bool "stabilize", int "tradius", bool "MT", int "aapel", int "aaov", int "aablk"). tradius can be 1, 2 or 3 for choosing MDegrain1,2 or 3. MT option can be turned ON.
And added some code for motion estimation.
Added NEEDI3 too as AA.

And I have remove some antialiasers from the avs, like maa and daa, 'cause they are in AnimeIVTC... so... But I have added in the Requirements Pack the AnimeIVTC.avsi.

Best Regards and check the 1st page ;)

As far as I can see, this is already built-in, via the line
Spline36Resize (w, h, 0, -0.5, w, h * 2)
in function santiag_dir.

Weird, did you try it out on any sample?

I double checked that I copied the function correctly, and used different sources, they all seem to exhibit the shift (like the old NNEDI before the cshift was implemented)

[Gavino]

Weird, did you try it out on any sample?
No, I didn't - I just accepted it at face value.
Looking at it again, I think it should be
Spline36Resize (w, h, 0, +0.5, w, h * 2)

Also it looks to me that strh and strv are the wrong way round - strh affects vertical and strv horizontal.

[poisondeathray]

Yes the "+" fixed it , thanks Gavino . I haven't tested the strh or strv

[poisondeathray]

To cretindesalpes or Gavino or anyone else:

Regarding the santiag() function I have some observations & questions:

When it's a YV12 / YUY2 source, the Spline36Resize (w, h, 0, +0.5, w, h * 2) seems to fix the shift

When it's a RGB24 source, the Spline36Resize (w, h, 0, -0.5, w, h * 2) seems to fix the shift

1) Why would this be?

2) Is it possible to modify the function to automatically adjust for this (maybe if/then statements or conditional ) ? My programming skills are NIL :)

The usual reason for such differences is that Avisynth processes RGB 'upside-down', so the shift is in the opposite direction. However, here I would expect it to 'come out in the wash', since the direction of the shift is a consequence of the use of field=0 in the call to nnedi3(dh=true). Perhaps it is actually a bug in nnedi3's RGB handling. (I didn't even realise till now that nnedi3 accepts RGB, its nnedi predecessors didn't.)

Whether the fault lies with santiag or with nnedi3, a fix/workaround would be
shift = IsRGB() ? -0.5 : 0.5
Spline36Resize (w, h, 0, shift, w, h * 2)

EDIT: Tests suggest this is a fault in nnedi3 - see here.

[poisondeathray]

Thanks Gavino

The cshift parameter for nnedi2_rpow2/nnedi3_rpow2 isn't affected by YV12 /YUY2 vs. RGB ; is the same "workaround" being used there ?

[Gavino]

The cshift parameter for nnedi2_rpow2/nnedi3_rpow2 isn't affected by YV12 /YUY2 vs. RGB ; is the same "workaround" being used there ?
I guess that's really a question for tritical - I can only speculate.

What I do see is that if nnedi2/3_rpow2 is called without the cshift parameter, it produces different results for YUY2 and RGB.
That's not necessarily wrong - since that function has no 'field' parameter to say where the original pixels should end up, the function is free to do what it likes - but it seems anomalous.
When cshift is specified, I guess the implementatation takes that difference into account, so the final result is correct.

[Archimedes]

I've changed the posted function santiag (http://forum.doom9.org/showthread.php?p=1393006#post1393006) a little bit.

Santiag has now three parameters: type, strh and strv. Type means the anti aliasing type. Possible values are "EEDI3", "NNEDI2" and "NNEDI3". strh is the strength for the horizontal anti aliasing and strv is the strength for the vertical anti aliasing. Default values are: type="nnedi3", strh=1 and strv=1.

Contrary to the first posted function, santiag(strh=0, strv=0) now means no anti aliasing. I've also corected the center shift. With NNEDI3 as type, the center shift now works correct for all possible input clips (YV12, YUY2 and RGB24).

Requirements:
LoadPlugin("plugins\EEDI3\eedi3.dll")
LoadPlugin("plugins\GScript\GScript.dll")
LoadPlugin("plugins\NNEDI2\nnedi2.dll")
LoadPlugin("plugins\NNEDI3\nnedi3.dll")

function SantiagMod(clip input, string "type", int "strh", int "strv") {
type = Default(type, "NNEDI3")
strh = Default(strh, 1)
strv = Default(strv, 1)

input

strh > 0 ? AntiAliasing(type=type, strength=strh) : NOP()
TurnLeft()
strv > 0 ? AntiAliasing(type=type, strength=strv) : NOP()
TurnRight()

function AntiAliasing(clip input, string "type", int "strength") {
input

GScript("""
if (type == "EEDI3") {
EEDI3(dh=True, field=0)
for (i = 2, strength) {
EEDI3(dh=False, field=(i + 1) % 2)
}
}
else if (type == "NNEDI2") {
NNEDI2(dh=True, field=0)
for (i = 2, strength) {
NNEDI2(dh=False, field=(i + 1) % 2)
}
}
else {
NNEDI3(dh=True, field=0)

}
}
""")

Spline36Resize(input.Width(), input.Height(), 0, 0.5, input.Width(), input.Height() * 2)
}
}

Also it looks to me that strh and strv are the wrong way round - strh affects vertical and strv horizontal.
For me, it looks correct.

[Gavino]

For me, it [ie strh, strv] looks correct.
OK, I understand your terminology now.
I was confused because I saw that strh affected vertical resampling and strv horizontal resampling. However, by horizontal anti-aliasing, I think you mean fix (near-)horizontal lines, which requires vertical resampling, and vice versa. Correct?

The code can actually be simplified a bit. The Evals are redundant and, since string comparison is case insensitive, there is no need to convert the type string to upper case. In santiag_dir and santiag_stronger, 'type' and 'strength' should not really be in quotes, since they are not optional parameters there.

For example, santiag_stronger could be rewritten (according to taste) as
function santiag_stronger(clip c, string type, int strength) {

I was confused because I saw that strh affected vertical resampling and strv horizontal resampling. However, by horizontal anti-aliasing, I think you mean fix (near-)horizontal lines, which requires vertical resampling, and vice versa. Correct?
Yes.

In the meanwhile, I have changed the function again. Now it is an iterative (non recursive) function, called "SantiagMod". It is easier to unterstand than the recursive function. This version looks also more pleasant to me. :)

Is there any documentation on aaf()? I want to know what each value does before I start tweaking some settings.

^^+1!

BTW Results with aaf() look good and it runs in realtime on my machine, so please tell us more about it.

I'm glad that script we assembled is still being improved. But let me remind you the original idea behind it.

I needed a script that would:

Anitalias anime. Resulting script did marverls on anime, but looked weird on real video. See why below.
Only work on edges and lines. For that I spent some time searching for a good mask. Don't remember what script I took it out from, but it was quite unique and much better than usual Sobel. Now anime contains a lot of contrasting edges and lines. Real video doesn't contain as much. It is unpredictable, which part is affected by script in each frame.
Make lines thiner and finer. For that warpsharp is used. I see no reason to use it on real video.
Darken the lines, so they are still visible after everything done on them. Again, why would someone do that on real video?
Do some postsharpening. That just needed to be done. Unrelated to video type.
Soothe lines shaking. In some anime horisontal scene moving introduces vertical lines shaking. The script we had so far made that shaking much more noticable. That's where motion compensation is used for soothing (great thanks, Didee!) Never seen vertical lines shaking in real video.

So you guys testing it on real video is confusing to me. Is new script tuned for it? Got to test it for anime and see if settings are good for it.

Now what the hell with all the interpolators? I used to use EEDI2 for antialiasing real video. Really smoothes some lines, but also blures the picture. In this script Sangnom did just as good as EEDI2, worked twice as fast and didn't introduce a shift like EEDI2 does. So I just threw EEDI2 out of it, it really wasn't needed. But in your script I see all kind of edge-directed interpolators. Apart from EEDI2 they are all quite sharp. They don't do any antialiasing at all. Look at the small AA functions you use. They all use Sangnom. I suggest you take out EDIs from your script at least for the sake of stopping confusing newcomers, making them think that EDIs are good for antialiasing.

I've share the last version of it. Topic updated! I'll in the future try to update more, and do some new stuff.

Cheers

I've been trying to add AA to screenshots/videos from an old XBox game, and though LSharpAAF certainly makes things easier I could still use some help in getting good results. The XBox game in question is called Panzer Dragoon Orta, and I'm currently running it from an Xbox360 (the Xbox360 is capable of emulating certain original Xbox games, this is one of them). I'm capturing the game over HDMI in 720P, and I assume the XBox360 is simply upscaling the image since the original game didn't run in HD resolutions. So basically this is what I'm getting:

Screenshot 1 (http://i361.photobucket.com/albums/oo53/Radik2/PanzerDragoon/PanzerDragoonOrta_1.png)
Screenshot 2 (http://i361.photobucket.com/albums/oo53/Radik2/PanzerDragoon/PanzerDragoonOrta_4.png)

From what I've tried on these images LSharpAAF(aatype="eedi3") seems to deliver the best results:

Screenshot 1 - EEDI3 (http://i361.photobucket.com/albums/oo53/Radik2/PanzerDragoon/PanzerDragoonOrta_1_EEDI3.png)
Screenshot 2 - EEDI3 (http://i361.photobucket.com/albums/oo53/Radik2/PanzerDragoon/PanzerDragoonOrta_4_EEDI3.png)

But given how little I know about all these AA methods being used I though someone here might be able to help me get better results. Any help would be appreciated.

Does the whole game look like that?
If so, let me cook something alternate up.

Meanwhile:
TurnRight()
Merge(SangNom(0,255).SangNom(1,255),Merge(SangNom(1,255),SangNom(0,255),0.5),0.25)
TurnLeft()
Seems to look "alright".

Edit: And if that's how it looks, here's another:
PointResize(Width/2,Height/2)
TurnRight()
Merge(SangNom(0,255),SangNom(1,255),0.5)
TurnLeft()
NNEDI3_rpow2(2,0,0,1).SangNom(0,255)
Which looks less messy.

Thanks Bloax. This is basically how the game looks yes, although I uploaded some actual gameplay footage here (http://www.megaupload.com/?d=42YMLISZ).

The second script does seem to deal with the aliasing nicely, although it also softens the image more, which I understand is somewhat inevitable when adding anti-aliasing. Here's a comparison (http://i361.photobucket.com/albums/oo53/Radik2/PanzerDragoonOrta_comparison.png), from left to right is the original, LSharpAAF(aatype=eedi3), your first and then second script. I didn't notice it at first but eedi3 does something weird to the background as well. The last script seems to lose a bit more detail than I'd like. An unfortunate side-effect is also that the game has subtitles at some points and your two scripts seem to add artifacts to those...
