New filter: HQDering

[mf]

Maybe useful to some people: edge unfiltering.
HQDering(smoother="Unfilter", params="-50, -50")
Fixed some nasty oversharpening on hair highlights (the anime "head and shoulders" effect ) for me, while maintaining a lot more sharpness than a brute-force unfilter.

I know this thread has been dead for a while but I just thought I'd make a comment. This is a really great at deringing, but would it be possible to add a parameter like in BlindDeHalo which you can set the width of the ringing you want to eliminate? Or would this just destroy the great amount of detail that this retains as compared to other deringers? Here is a shot to show what I mean (especially look at the hat); it would be nice so then edges like that could be almost fully deringed.

I try to use this script but when I load it into VirtualDubMod it automatically closes itself. I don't get an error or anything, it just closes. Here's a sample of my script.

code:

LoadPlugin("C:\dgmpgdec110\DGDecode.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\Decomb521.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\deen.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\UnFilter\UnFilter.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\VSFilter.dll")
LoadPlugin("C:\Plugins\MaskTools-v1.5.6\MaskTools.dll")
Import("C:\Plugins\LimitedSharpen.avs")
Import("C:\Plugins\HQDering-v0.1.avs")
Mpeg2Source("myd2v.d2v")
Telecide(hints=false,order=1,post=2,blend=true)
Decimate(cycle=5,quality=3)
Crop(6,6,-4,-6)
Deen("a2d",2,10,12)
UnFilter(-10,-10)
TextSub("C:\SUBTITLES\MYSUB.ssa")
Subtitle("Something",text_color=$F2F200,x=275,y=40,first_frame=0,last_frame=221,size=20)
Subtitle("Something",text_color=$C0C0C0,x=230,y=60,first_frame=0,last_frame=221,size=15)
Lanczos4Resize(640,352)
LimitedSharpen(ss_x=2.0,ss_y=2.0,Smode=3,Lmode=1,overshoot=0)
HQDering()

Empty plugin folder ...

[-IRnoob-]

I don't think so, I have a separate plugin folder besides the AviSynth directrory. Whenver I try to use HQDering it causes that error. When I take it out of my script and serve it into VirtualDubMod again it works fine.

HQdering uses "YV12Layer()", which was present in older MaskTools versions, but isn't anymore in v1.5.6. You either have to use an older MaskTools version, or adapt HQdering by replacing YV12layer through Overlay() or yv12LUTxy().
The latter way is recommended

[-IRnoob-]

I may sound like an idiot but how do I do that?

[Didée]

Try to replace the YV12layer-line with

Overlay(amplifiedmask.Invert(), thickmask, mode="multiply").greyscale

It's probably not the exact same operation, but I cannot figure that out right now.
After all, HQdering could undergo a buch of optimizations ... given that the available tools have matured a lot since then. But HQdering is mf's baby, not mine - and if I would alter it, then it wouldn't be "HQdering by mf" anymore ...

Then name it "HQdering by mf - hacked by Didée" or so...

As you might now, this somewhat childish style is not mine.
Moreover, I've little need to "hack" mf's scripts - I do have my own solutions.

Aaargh! Don't say the *EX-word!

- Last steps are often the most difficult ones. That alone is reason enough ...

- Then I *must* process lots of stuff, since my HDs are are really bursting now - I could already spot some cracks in them (I've stuff worth half a year of encoding time, waiting to get done)

- And on top of that, the German Doom9 collegues urged me to write a "DeLogo Guide" - seems without additional guidance, they can't do anything other than blurry-box-smearing ... (Not all of them, but many ...)

- Plus I must prepare new photographs from me, for my family ... they only see me from behind, sitting at the darn machine. Last time I turned around, my wife scared "who are you"
