Just try it...

Guess it blows all halos away !?!

Bye

dbzgundam · 11th December 2004, 21:05

Just... Wow.

It eliminated all the halos on all of my EE'ed discs (That I tested), and even helped TV rips of anime!

Soulhunter · 13th December 2004, 00:33

Yeah, its like... magic !!!

Code:

BlindDeHalo2(3,3,200).LimitedSharpen()

But don't you think that's the story's end: christmas is still to come ...

@Soulhunter,

Such a nice girl

Why do you blur her so much with the result that you can hardly seen her face anymore?

Kagura · 13th December 2004, 20:00

*snickers*

Blurring something so badly that you have to call a sharpener to recover details? That doesn't sound like good filtering. Maybe you should try toning down the strength of dehalo.

Off topic: Limitedsharpen is best as smode = 1

Soulhunter · 13th December 2004, 20:27

@ Wilbert

Well, its was only a "remove all the halos" test...

Guess BlindDeHalo2(3,3,150) would be already enough !?!

Take a closer look @ the source, imo it looks already very blurry...

The sharpness is mainly "virtual" and caused by the edge-enhancement !!!

Nah, this sounds like -> BlindDeHalo2 does the opposite of LimitedSharpen...

BlindDeHalo2 removes halos, but LimitedSharpen sharpens without producing halos !!!

Chainmax · 13th December 2004, 23:44

Wow, the last picture looks so much more natural than the first one

. Was that really just BDH2 and LS at work?

P.S: there is too much smoothing going on though, it's especially noticeable in the necklace (or whatever that thing around her neck is called).

You should try that pic again with the fist BlindDeHalo Didee posted I like that one little better does not seem blur or soften near as much.

14th December 2004, 01:51

Your new version is quite nice. I use it in conjunction with HQDering, which seems to get rid of some of the dark halos that BlindDeHalo misses, and I get quite nice results.

Now that's more like it. =P

Mainly coz BlindDeHalo2 dont processes the chroma, but the sharpening does...

Didée · 14th December 2004, 10:25

Soulhunter:

Thanks for holding up

Next time I need a varlet to rage against some windmills, I'll call ya ...

BTW, poor Jeanette shows _severe_ bad'n ugly oversharpening, and there's not too much left hiding behind the artefacts... Is that an "original" source, or did you add some enhancement manually?

Wilbert, Kagura:

You should give a 2nd thought on the topic. Know the story about the mathematician that inspected the two only barber shops in a small village, found one shop dirty&ugly with the barber's hair terribly dressed, the other shop bright & clean with the barber having his hair in perfect shape, and then went to the ugly shop to get his hair done ... ?

I fully understand your reactions: "Okay, halos might be gone - but it looks so unimpressing afterwards, has so little contrast..." - and IMO that's exactly how it has to be: First remove the "wrong" sharpening, but keep what's behind the artefacts. Then (eventually) go on and make a better enhancement than the original one.

To find a (too short) explanation about what's the actual problem and what's my opinion about it, as well as an example of what BlindDH2 basically is trying to achieve, please look here (Morpheus' pictures are the deal).

To convince yourself, make this little experiment:

Code:

a =   anysource()
b = a.UnsharpMask(127,3,0)     
c = b.BlindDeHalo2(3.1,3.1,110)  # around these values ... fork a little around 
a = a.subtitle("orig")
b = b.subtitle("enhanced")
c = c.subtitle("BlindDeHalo2")

interleave(a,b,c,a)

I enhanced the halos with some "slight" sharpening !!!

Unfortunately some of my tv channels really look like this...

But thats mainly caused by the very bad analog signal I receive !!!

Kagura · 14th December 2004, 19:31

Didée, I wasn't insulting blinddehalo. Rather, I merely thought that Soulhunter used too strong values in reducing halos on his first two pics.

SirCanealot · 17th December 2004, 20:17

Has anyone got any suggested settings or advice for using this on anime?
I can get it to remove SOME of the halos, but it does as much damage to random high-contrast parts of the picture as it does EE removal.

Thanks all.

I'll post some screenies and what settings I'm trying if anyone wants - I'm really having little luck with anime and this :/

Can someone give me a direct download link for this filter, please? I wish to test it on some DV footage.
