SSXSharpen in realtime....

Well, its not really SSXSharpen...

But this combo looks imo 90% the same!

Code:
# The plugins

aSharp(0.4,0,0).aWarpsharp(3,1,bm=3,cm=0,thresh=0.99)
Source:


SSXSharpen:


The combo:



Thanks n' Bye

Very nice indeed. At the same time, it looks like in some areas that the combo gives even more detail enhancement then SSXSharpen.

If you dont like this effect, just lower the tresh of aSharp!

Btw, if you "hack" this combo into LimitedSharpen...

Code:

# LimitedSharpen
#
# A multi-purpose sharpener by Didée, hacked by Akirasuto n' Soulhunter... ^^
#

function LimitedSharpen2( clip clp,

Even better looking. I will definitely be doing some testing with that.

Does the "non hacked" version of LimitedSharpen work for you?

Going to test this LimitedSharpen hack my self the pic looks pretty damn nice.

BTW Soulhunter what does the call script for the hacked LimitedSharpen look like?

Nah, not at all...

The combo itself should run @ "above realtime" speed!

The default is...

LimitedSharpen2(Smode=4)


But you can disable super-sampling...

LimitedSharpen2(ss_x=1,ss_y=1,Smode=4)

Thanks!

Looks like the only real change is Smode to 4 so one could still use the full LimitedSharpen call like the following correct?

LimitedSharpen2( ss_x=1.0, ss_y=1.0,
\ Smode=4, strength=40, radius=2,
\ Lmode=1, wide=false, overshoot=1,
\ soft=false, edgemode=0, special=false,
\ exborder=0 )

Under investigation. Looks promising, but I have some doubts about speed advantage in LS (the currently used sharpeners by themselves aren't slow, as well ... it's the complete bunch of operations together that suck the CPU time).

And let me ask here, too: in *what* way have the used DLLs of aSharp and aWarpSharp been modified? To know what's actually going on would help on further improvement ... after all, LimitedSharpenEX gets closer to completion - but perhaps a few days more would be beneficial

Changed from what? They haven't been changed for quite some time since MarcFD stopped coding.

I heard a rumour those DLLs were "slightly modified". But looking at the file dates, and remembering that MarcFD wasn't the busyiest with releasing sources ...

Well, at least you dont need super-sampling anymore...

And getting SSXS a'like results in realtime is enough for me!

Have to ask pruned for the exact changes...

IIRC it was about "finer precision" or something like this!?

Well, since it looks like he reverse engineered it (adding an extra tweak parameter (what's it do? ) and more chroma modes doesn't really work with mere patching) - could you ask him if he'd release the source? The aWarpSharp used in ffdshow never really worked right for me, and this would be a great opportunity to get it working...

One can dream, right?

np: Autechre - Lowride (Incunabula)

He didn't reversed engineered awarpsharp since he made awarpsharp to begin with ^_~

The modified awarpsharp does a shock filtering and the asharp to do real sharpening, iirc. I could be wrong, though ^^;

Edit: Oops, I was corrected... wrong person.

I thought aWarpSharp was made by marcFD?

btw, the source of asharp should be available (at least I have the "old" source) since it's GPL.
