SimpleResize-like

[Marc FD]

hi, i coded a mmx-optimised YV12 filter very close to simpleresize.

if tom is not against that, i can release it.

it's a faster than PointResize in YV12 or SimpleResize in YUY2

waiting.....;)

[ffroms]

Where is it? Can you put it on your site?

Marc -

By all means, release it.

I actually took another crack at YV12 SimpleResize last night, some weeks after writing it. But it still seems to be terminally busted, so I can't release mine yet.

But please don't call it SimpleResize since that would probably come back to haunt us forever. ;)

no problem, tom, i called it FastBilinearResize.
i've done a bicubic version too, because my project is to make a hyperfast bicublin resampler, IMHO a very good trade-off between speed and quality. so it would be a 3 in 1. i'm gonna release some beta stuff today ^^.

Can you implement 2 in 1, please?
Crop + FastBicubicResize in one?

Any more thoughts on a resizer that thakes YUY2 input and converts it to YV12 on output, like I suggested in this thread (http://forum.doom9.org/showthread.php?s=&threadid=40057) a while ago. The bicublin would be wonderful to have modified in this way.

[Marc FD]

okay, here's the stuff.

i tested it a lot.

i hope you will like it :)

hakko, this bicublin is unfiltered, i'm not sure that using YUY2->YV12 resising will lead to better quality. i'll try anyway (C coding is so fast ^^)

@Marc FD,

Sorry for being OT, but have you read this thread (http://forum.doom9.org/showthread.php?s=&threadid=42871).

@wilbert

i know, i know, i'm gonna do that this WE.
that's one of the last thing i'll do, so i take my time ^^

You are prodigious powerful! :D
One month - one new filter!

[Marc FD]

thx Harry

well, in fact, i've coded much more than that. edeen & atc are fully working & optimised, but i still didn't released them. i'll do that this WE too. they would be my 2 last releases.

so, does the stuff work ? i've spend many hours of debugging, i'd like to know how perform the last filter i'll probably write before a long time.

First tests seem ok. Hard to say about visual quality, I need to test more to say, but seems OK.

About compressibility, BicublinResize with default parameters gave me similar results than bicubic 0.6.

"that's one of the last thing i'll do, so i take my time " -> are you too busy (your "bac") or what else ? ;)

Cheers,
FuPP.

[wotef]

this looks good

could you make the filter raise an error to the user if not fed a YV12 source?

really!
that's the reason of my "waiting"...;)

>"that's one of the last thing i'll do, so i take my time " -> are you >too busy (your "bac") or what else ?

no, i'm just tired of filter devel, i programmed a lot of stuff and i simply don't need anything more ^_^

>could you make the filter raise an error to the user if not fed a YV12 >source?

yep, i'll do it, but it's only a beta, i want things to work first, i play after ^^

[seewen]

Really nice filters.. I don't see any difference ( but didn't tested a lot ) between FastBilinear or Bilinear..

But FastBilinear is really faster..

-------

But there's a little bug with you filters. I saw this with "FastBicubic" & "Bicublin" ( not with "FastBilinear" )
When I try this script ( source = DivX 528@288 :

AviSource("*.avi", false)
#Crop(4,30,-4,-30)

FastBicubicResize(640,288,1/3,1/3)
#BicublinResize(640,288)


With FastBicubic, there's a Red-Magenta Vertical Line at the extreme right of the picture. ( http://seewen.levillage.org/download/FastBicubic_nocrop.jpg )
If I un-comment the crop() command of the script, the line turn Green ;) ( http://seewen.levillage.org/download/FastBicubic_crop.jpg )

With this script + "Bicublin", the line turn White ( difficult to see, I didn't take picture ).

-----------

But what is more strange, is that if I open this script ( crop() un-commented ), the Green line appear.
Then if I comment the "FastBicubic" line ( with VdubMod editor ) and un-comment "Bicublin" the line turn white.
But then, if I comment "Bicublin" and un-comment "FastBicubic", the green line doesn't appear...
And if I comment "FastBicubic" and un-comment "Bicublin", the white line doesn't appear too !

Then if I just close the script. and re-open it, the line doesn't appear.. But if I close VdubMod and Re-open it, the green line come back..

And changing crop values changes color, or make line disapear ( like #Crop(2,30,-4,-30) or #Crop(4,30,-2,-30) for example ).


Sorry, I cannot be more precise, as this problem is so special.. ;)

A+

P.S.
Using avisynth 2.50 ( 10.1.2003 ) and the last VdubMod and Vdub ( bug appear in both ).

[Marc FD]

no, no, it's a normal problem.

it took my several hours to tweak the boders, my best advice is to oversize and to crop after resize. it's so fast anyway, and the problem only occurs with very specific input/output sizes

[HarryM]

FastBicubicResize works O.K. for me, nice sharp look.
Only compressibility is worse than built-in BicubicResize. But FastBicubicResize is pretty fast... :cool: :cool: :cool:

Hi Marc FD,

your filter is really amazing fast!!

[DickModeOn]
I get nearly 44fps in first pass and almost 51fps in second pass... (XP1600, 256 RAM, single 60GB_HD without raid, WinXP-SP1)
[/DickModeOff]

I've used the following simple script:


LoadPlugin("D:\Tools\AVISynth_Plugins\Avisynth_2.5\MPEG2Dec3.dll")
LoadPlugin("C:\Tools\AVISynth_Plugins\Avisynth_2.5\BicublinResize.dll")
mpeg2source("D:\Movies\the 51st state\51.d2v")
crop(2,8,716,553)
BicublinResize(544,288,0.75,0.5)


but I have to:
seewen
With this script + "Bicublin", the line turn White ( difficult to see, I didn't take picture ).

I can notice a line as well, but not a the right - I can notice the line at the bottom ( a blue, very thin line)

I did test relatively a lot but the standard parameters

BicublinResize(544,288,1/3,1/3)

and leaving the b,c values away

BicublinResize(544,288)

gave me same result_a thin blue line @ the bottom. To soothe you a bit, this line did appear only at one unharried scene (within a 1min test_clip). I didn't attach an image because it's not very noticeable within a picture but it is present.

my 2 cents and with kind regards

I'm not sure if it's ok to bump such an old post. I need such a fast bilinearresizer for some batch svcd encoding. Is this filter still around, or is it obsolete anyway these days (meaning the standard resize has improved).

I made some tests recently for some batch svcd encoding with the result, that SimpleResize is still the fastest. FastBicubic is as fast as Lanczos, Bicublin is a bit slower than SimpleResize.
