Did I hear you correctly when you said that you plan on integrating LimitedSharpen into iip? Do you have an estimate when you would have something ready to share?

It would be very nice if you gonna integrate limitedsharpen into iiP...

There's surely the problem about the encoding speed and how to merge some funktions to get more FPS of the encoding.... but I'm not an advanced so i can only imagine that there would be more problems someone wanna solve


PS: LimitedDarken? Let me imagine what that can be

Does it perhaps go in direction of Mf's Toon-function? Maybe to control the darkening of lines and avoid thick lines?...

It also could be a controled color-correcting function??

Give us some hints please

Okay. For all the impatient people, a little preview: "The quick hack".

No guarantees, no claims, no responsibilities.

No support.

No need to report any bugs.

LimitedSharpen works really pretty but it's very slow. It slowed down my encodings about 5 x.

Funny thing is, one of LimitedSharpen's main appeal compared to the other sharpening methods is it's speed!

This is my script:
Import("C:\PROGRA~1\GORDIA~1\AviSynthPlugins\limitedsharpen.avsi")
LoadPlugin("C:\PROGRA~1\GORDIA~1\AviSynthPlugins\dgdecode.dll")
LoadPlugin("C:\Program Files\GORDIA~1\AviSynthPlugins\MaskTools\MaskTools.dll")

mpeg2source("D:\My Documents\My video\Mind\Mind.d2v", idct=0)
crop(4,6,712,562)
LimitedSharpen()
LanczosResize(592,320)

Any ideas why it is so slow ?

Well, there are scripts out there that slow down the encoding by factors 10x ~ 30x, or even more ...

Before you get too disappointed, try the following:

--------------------------------------------
crop(4,6,712,562)
Lanczos4Resize(712*4,562*4).XSharpen(255,255)
LanczosResize(592,320)
--------------------------------------------

After trying *that*, tell again how slow LimitedSharpen really is ...


However there are two or three steps to make it faster:

1.
Use crop(4,6,712,562,true) because of memory related Avisynth-internal details.


2.
You are doing one resizing step too much. Try

--------------------------------------------
crop(4,6,712,562,true)
LimitedSharpen(dest_x=592,dest_y=320)
--------------------------------------------

This won't give you the real breaktrough either, but it will be faster.


3.
Reduce supersampling (but quality as well). Try

-----------------------------------------------------------------------------
crop(4,6,712,562,true)
LimitedSharpen(ss_x=1.0,ss_y=1.0,dest_x=592,dest_y=320,Smode=2,strength=40~~80)
-----------------------------------------------------------------------------


Rule of thumb: The better the result, the longer it takes.

(The reverse conclusion is not necessarily true, however)

I took a look at the alpha some hours ago and it looks cool ATM.

The speed is approx 2-3 FPS (Athlon XP 2600+ @ 2300 MHz on nForce 2 Dual Channel 521 MB RAM)

I think that could be the best quality improving filterfunction ever posted in this forum ... but i'm beginner

I am trying to use LimitedSharpen on a new encode I'm trying but for some reason warpsharp.dll can't be loaded. Does LimitedSharpen need it if it's going to be called like this: LimitedSharpen(ss_x=2.0, ss_y=2.0)?

No because then you are using Smode=3 (the default mode). If you use that mode, you only need MaskTools.dll.

BTW.. warpsharp.dll loads normally here.

I had inspected the avs and didn't catch any warpsharp calls except for unsharpmask, but I wanted to make sure. BTW, warpsharp usually loads without problems Has anyone else had any issues trying to load it?

if you reformated, you have to check if you have the msvcp71 and msvcr71 dlls in the system dir. other than that, no other loading problems for the japanese version of warpsharp I'm aware of.

LimitedSharpen washes out the color?

First of all if you have read my thread on using Avisynth in ffdshow for DVD playback you know I am using LimitedSharpen in an unorthodox manner for on the fly DVD viewing.

Here are the settings I use:

LimitedSharpen(ss_x=1.0,ss_y=1.0,Smode=3,strength=40)

If you look at the before and after pics you can see I get a much sharper image but the colors are faded compared to the original. So now I am wondering if there is a way to automatically compensate for that with little overhead and without having to mess with Hue & Saturation settings?

Thanks for any input

Here are the pics;

Before



After Limited Sharpen

That's not the fault of LimitedSharpen: It does not process chroma at all (the last step in the function is the merging of the unprocessed original color planes).

In these two pictures here it's a luma problem - there is much contrast missing, it looks like a gray haze was layed over the 2nd one.
Also note that none of your screenshots in the other thread actually show this problem, so ... dunno what it is, but something went wrong here.
