Yeah, the halos in that stream are just too strong for DeHalo_Alpha's current state. Here's a comparison:

Source:


Result:



Script:
Code:
DeDot()
ConvertToYUY2(interlaced=true)
ReYV12()
Interp = SeparateFields().SelectEven().EEDI2(field=0)
TDeint(order=0,field=0,edeint=Interp)
MergeChroma(Crop(0,2,-12,0).AddBorders(12,0,0,2))
Crop(16,4,688,558,align=true)
DeHalo_Alpha(rx=2.5,ry=2.5,darkstr=1.2,brightstr=1.2)
M=DePanEstimate(PixAspect=1.094,Trust=1.0)
R=2
DePanInterleave(Data=M,PixAspect=1.094,Prev=R,Next=R,Mirror=15)
DeGrainMedian(limitY=6,limitUV=8,mode=0)
TemporalSoften(2,0,50,mode=2)
SelectEvery(R+R+1,R)
GaussResize(512,384,p=100)
DeHalo_Alpha(rx=2.5,ry=2.5,darkstr=1.2,brightstr=1.2)
LimitedSharpen(SMode=4,LMode=3,Strength=150,wide=true,soft=75)
The final encode is intended to be 512x384, but for comparison's sake I made the result the same frame size as the source. By the way, is it me or does this have some blending?

Heavy halos... I used my script, which i use for my own encodes and the result is this (no smoother... only my own dehalo-script):



what do you think?

The result is quite good, could you post your dehalo script?

Don't be shocked. It is frickled and modiefied thorugh the time... And very slow:
Code:
function CEA2(clip c, int "EdgeBias"){
EdgeBias = default(EdgeBias,17)

# First remove oversharpened Borders...
c
ConvertToYUY2().FixVHSOversharpL(30,12,8).FixVHSOversharp(30,14,10).ConvertToYV12()
BlindDeHalo3(PPmode=1)
oversharp=last

pT=PreWitt(thin=true)
pT1=FineEdge(EdgeBias)
pT2=pT1.Levels(10,1,110,0,255,false)

FineMask=pT2.Expand().Inpand().Inpand().Inpand().Levels(50,1,160,0,255,false).expand().inflate().inpand()
StrongMask=pT2.Inpand().BilinearResize(m4(width/3.0),m4(height/3.0)).InPand().Expand().BilInearResize(width,height).Expand().Levels(0,1,30,0,255,false)
Fine=YV12LutXY(pT2,FineMask,"y 10 > x 0 ?")
Fine=YV12LutXY(Fine,StrongMask,"y 10 > 0 x ?")

edgeA=pT1
edgeB=edgeA.Levels(30,1,90,0,255,false)
edgeC=edgeB.BilinearResize(m4(width()/4),m4(height()/4)).expand().inflate().BilinearResize(width(),height())
ptTMP=YV12LutXY(pt,edgeA,"x 10 > y 40 > & x 0 ?")
edgeD=YV12LUTxy(edgeC,ptTMP,"y 0 > x 10 > & 0 x 1.3 * ?")

edgeE1=YV12LUTxy(edgeD,Fine,"y 0 > x 20 > & x y 1.3 * - x ?").deflate()
edgeE1=edgeE1.Levels(0,1,150,0,255,false).inflate()
edgeE2=YV12LutXY(ptTMP.inflate(),Fine,"y 0 > x 20 > & x y 1.3 * - x ?").inflate()
edgeE3=YV12LutXY(edgeB,FineMask,"y 10 < x 0 ?").inflate

# Now the Cleaning
# Attention: Cleaning of c, not oversharpened

c
# Clean The Edges
clean=Deflate().Inflate().BlindDeRingA(5,5,2,20,true,false,false)
clean=clean.Blockbuster(method="noise", detail_min=1, detail_max=32, mean=1, variance=2)
MaskedMerge(clean,EdgeE1,Y=3,V=1,U=1)

clean=last
clean=clean.UnSharpMask(250,1,0)
clean=clean.Blur(.2)
MaskedMerge(clean,edgeE2,Y=3,V=1,U=1)

anti=GetAntialiaseClip()
MaskedMerge(anti,edgeE3,Y=3,V=1,U=1)

#MaskedMerge(UnSharpMask(50,1,0),FineMask,Y=3,V=1,U=1)
}


function GetAntialiaseClip(clip c, bool "chroma"){
chroma = default(chroma,false)
faktor = 1.7
SangOrder=0
SangFakt1=90
SangFakt2=90

X=width(c)
Y=height(c)

Lanczos4Resize(c,m4(X*faktor),m4(Y*faktor))
TurnLeft().SangNom(SangOrder,SangFakt1)
TurnRight().SangNom(SangOrder,SangFakt2)

BilinearResize(X,Y)
sangnommed=last

chroma ? MergeChroma(c) : sangnommed
return last
}
I uses several filters: Fixoversharp, BlindDehalo, Sangnom,Masktools, FineEdge, BlindDeRing. BlindDering is a filter which i coded by myself. You can get it here: link. Here i wrote abouth this filter: forum-link

The general purpose is to build up a mask on a dehalod picture and use this mask to dehalo it with "blinddering". I tried to make here something like "don't remove-things, which are too file". General purpose is that even halos can't be removed blind when there are too many detail. So why should we try it?
Also look at "edgeC". This can be interpreted as "clean-radius". Bigger Value-> Bigger Radius. Till now i modified it for every movie individually.

maybe there is someone out there who can optimize this script.

BTW: It try also to antialliase (secure).

You should replace BlindDeHalo with DeHalo_Alpha, it's much better.

FredThompson, what do you mean?

HOLiC, not for now, but a modification is probably easy to do, just ask Didée if he has the time do it.

There was a broken link in an earlier post. Your source frame wasn't showing or you'd forgotten to add it to the post or something like that.

Standard disclaimer: May show gigantic bugs in masktools 2. Always use the latest alpha and always compare to the original.

If my mod starts showing results I'll post it too; right now it's not that much better. Don't work on it much though.

Seems to give identical results. From Porco Rosso R2 version:

Source:



DeHalo_Alpha(darkstr=.4) (old version):



DeHalo_Alpha(darkstr=.4) (Masktools 2):

1st I'd like to say: Keep up the good work !

and then I'd like to ask a silly question...

well, sometimes I like to over do it with the compression
and as a result of that I get some film alterations__which I'm able to get rid of at the cost of very little detail-loss.
The only thing I can't get rid of (without a greater-loss of detail) is some mosquito noise which is the result of that low bitrate.
My question is:
I know//at least I think I do.... that 'BlindDehalo3' and 'Dehalo_alpha' are made so they can be used to correct some things in a (source), but I was wonderin' how stupid will it be to use something like PPmode=-1 or -2 on a clean source to correct my issue?

thx
NO I wont give higher bitrates

Seconding that... any updates or new approaches ? Guess could zip over to the Dev forum but haven't spotted anything in an occasional browse.

Don't forget that this filter can also remove haloing caused by some sharpener filters so that is one more use for this filter. Dunno if FFDshow has this kind of a filter but I could image it would be very handy. Many thanx to the Didee and foxyshadis for their work!

IIRC, Didée is was very busy with other projects (Restore24 being one of them) and hadn't thought of further improvements. What I'd like to see is a renewed version of HQDering as requested in this thread. That or a standalone version of IIP's deringing.

where does the function "expand" live? I've updated a bunch of filters and this seems to have disappeared. I'm starting to wonder if AviSynth has a limit on the number of filters it will auto-load. warpsharp is pretty far down the alphabetical sort...

2.5.6 does have a limit (a bug, really), and that's one reason I keep filters split between an auto and manual load folder. 2.5.7 has no such limit.

Expand is part of masktools 1.x.

2.5.7a3 dates back to April. Is the alpha aspect only additional things which aren't in 2.5.6?
