A small mod (with new options, improvements...) needed for MCTemporalDenoise v1.0.00...
 Speed comparaison (with v1.9): Code:
LimitedSharpenFaster() = 17.4 fps LSFmod(defaults="fast") = 16.8 fps LSFmod(defaults="slow") = 7.6 fps Last edited by LaTo; 5th October 2009 at 18:02. |

w00t, LaTo does it again
 so atm I'm using LimitedSharpenFaster(ss_x=1.0,ss_y=1.0,strength=40) an improved(speed-wise? PQ-wise?) LSFmod call would be : LSFmod(Smode=3,ss_x=1.0,ss_y=1.0,strength=40) ? I dunno what do to with Smethod... any chance you could use the limitedsupport.dll for realtime speed increase ?  EDIT: w00ps, LSF is 310fps, LSFmod is 113

ok, thanks for the tip!
so LSFmod(Smode=3,Lmode=1,ss_x=1.0,ss_y=1.0,strength=40,soothe=false) is 290fps still a bit slower than the LSF that uses limitedsupport.dll, any chance you could use it ? I might as well mod your script and call it LSFMod2() is there any point using this LSFMod call over the original one ? you said you "fixed" some stuff if I got it right

Very interesting. I will have to play with this. Oh, and I can't wait for Didee to spin by. He may offer some great insight.

LaTo, congratulations for the good work.
In the comments write that the "SdmpHi" work in the opposite way than "SdmpLo". Small number for "SdmpHi" mean big reduction for "big sharpening changes" and usefull numbers are 15~30.

SdmpLo: the higher, the stronger reduction SdmpHi: the lower, the stronger reduction Quote:
new Smode=4 + Smethod=1 is the old Smode=4 new Smode=5 is the same as Smode=4 but with a fix in the formula (no Szrp shift with SdmpLo&SdmpHi!=0) new Smethod=3 is the same as Smethod=2 but softer, I like the result... maybe too soft, so Smethod=5 is the same as Smethod=3 but sharper Smethod=4 is the sharpest... I will post some screenshot later

So, this is some screenshots about Smethod with LSFmod(Smode=1,strength=300,Smethod=X)... (High strength to see better)
Screenshot 1: Smethod=1 Smethod=2 Smethod=3 Smethod=4 Smethod=5 Screenshot 2: Smethod=1 Smethod=2 Smethod=3 Smethod=4 Smethod=5 In order of strength: - 1 < 3 < 5 < 2 < 4 + In order of speed: - 5 < 4 < 3 < 2 < 1 + In order of quality: - 4 < 2 < 1 < 3 < 5 + By default in Limitedsharpenfaster: With Smode=3, similar as Smethod=2 is used... (It's sharp but produce some ugly artefacts... look at the sky in the screenshot1 & in the back of the chair in the screenshot2) With Smode=4, similar as Smethod=1 is used... (It's too soft, especially with a default power at 2 and an "auto SdmpLo" changing with strength) By default in LSFmod: With Smode=1, Smethod=5 is used... (It need a sharp Smethod because this Smode is linear sharpening) With Smode=2&3, Smethod=3 is used... (This Smethod is soft but it's compensated by the Spwr parameter of nonlinear sharpening) Rmq: You can change Skernel to 19, it will be sharper... but there are little artefacts Last edited by LaTo; 28th November 2008 at 18:35. |

About the difference between Smode4 & Smode5 :
  In the original version, when SdmpLo or SdmpHi != 0 the curves don't pass through Szrp... So, in the corrected version, all curves pass through Szrp... It's not very important, but I'm a perfectionnist EDIT: Oups I forgot the 1/Spwr when I made these graph! It isn't a problem, the principle remains the same... I will correct these graph when I have time  EDIT2: Now all is ok, curves are fixed

all this stuff doesn't make much sense to me, I think I'll stick to the original LSF that uses limitedsupport.dll

1. There is something wrong in your graphs. The bellow graph is from Didee:  Light blue shows "Szp=16, Spower=4, SdampLo=0.01, SdampHi=255". Dark blue shows "Szp=16, Spower=2, SdampLo=3, SdampHi=255" Dark green shows "Szp=16, Spower=4, SdampLo=4, SdampHi=24" 2. From the original SeeSaw function: Sstr = default( Sstr, 1.5 ) Szp = default( Szp, 16 ) # or 16+2 Szp = Szp / pow(Sstr, 1.0/4.0) / pow( (ssx+ssy)/2.0, 1.0/2.0 ) SdampLo = default( SdampLo, 5) # Spower+1 SdampLo = SdampLo / pow(Sstr, 1.0/4.0) / pow( (ssx+ssy)/2.0, 1.0/2.0 ) from your LSFmod: strength = default( strength, Select(num, 100 , 100 ) ) Szrp = default( Szrp, Select(num, 16 , 16 ) ) strength = float(strength)/100.0 Szrp = Szrp == 0 ? 1 : Szrp SdmpLo = default( SdmpLo, Select(num, strength/25 , 4 ) ) If you want explain the differents.

LaTo one more comment.
I prefer separate overshoot value for edges and non edges instead of Lfactor, but this is just my opinion, your mod is nice. Thanks to Didee for the wonderful ideas. Edit Another comment. Code:
### SOFT sharpdiff = mt_makediff(tmp,last,U=1,V=1) sharpdiff = mt_lutxy(sharpdiff,sharpdiff.removegrain(19,-1), \ "x 128 - abs y 128 - abs > y "+string(soft)+" * x "+string(100-soft)+" * + 100 / x ?",U=1,V=1) soft==0 ? last : mt_makediff(tmp,sharpdiff,U=1,V=1) (ss_x > 1.0 || ss_y > 1.0) || (dest_x != ox || dest_y != oy) ? spline36resize(dest_x,dest_y) : last ### SOOTHE diff = mt_makediff(clp,last,U=1,V=1) diff2 = diff.temporalsoften(1,255,0,32,2) diff3 = mt_lutxy(diff,diff2,"x 128 - y 128 - * 0 < x 128 - 100 / "+string(keep)+ \ " * 128 + x 128 - abs y 128 - abs > x "+string(keep)+" * y 100 "+string(keep)+" - * + 100 / x ? ?",U=1,V=1) soothe ? mt_makediff(clp,diff3,U=2,V=2) : last.mergechroma(clp) return edgemode!=-1 ? last : edge.spline36resize(dest_x,dest_y).greyscale() }
