New Sharpening Function
Examples : 4x nnedi2, 4x nnedi2 New Sharpening, 4x nnedi2 limitedsharpenfaster smode4, 4x nnedi2 ssssharp.
Edit:Additional examples added, as requested. After reading this post by Didée I decided to take a crack at the problem of sharpening an interpolated or lowpassed image. Out of curiosity I tried the resulting function on a few difficult to sharpen noninterpolated sources (GITS R1 Special eddition, etc.), and it did very well (imo, of course). So here is a new, general sharpening function. Right now its named "blah". Because naming things is difficult, and naming it after what it is actually doing would require a paragraph long function call. Code:
Function blah(Clip c, Int "str", int "strv", int "strh", float "de", float "dev", float "deh", float "re", float "rev", float "reh", float "cstr", float "cstrv", float "cstrh") {# A sharpening function, Version 0.0 str = Default(Str, 4) strv = Default(strv, str) strh = Default(strh, str) de = Default(de, 0.2) dev = Default(dev, de) deh = Default(deh, de) re = Default(re, de/2) rev = Default(rev, re) reh = Default(reh, re) cstr = Default(cstr, 0.5) cstrv = Default(cstrv, cstr) cstrh = Default(cstrh, cstr) de = 20/de dev = 20/dev deh = 20/deh re = 20/re rev = 20/rev reh = 20/reh thrc = 72 thrcv = thrc thrcH = thrc thr2gv = 1/sqrt(thrcv) thr2gh = 1/sqrt(thrch) lp_V = C.NLLV_Variant4() Diff_V = mt_makediff(C, lp_V) lp_H = lp_V.NLLH_Variant4() Diff_H = mt_makediff(lp_V, lp_H) dev_ = string(rev) deh_ = string(reh) DeEmphasis = lp_H.yahr.yahr.Mt_Convolution(Horizontal=" 1 6 15 "+deh_+" 15 6 1 ", vertical =" 1 6 15 "+dev_+" 15 6 1 ", u=1, v=1) STRV_ = string(strv) Max_V = mt_luts( C, C, mode = "max", pixels = " 1 0 1 0 ", expr = "X Y  X Y  X Y  abs 1 + * X Y  abs 1 + "+STRV_+" 1 >= "+STRV_+" 0.5 ^ "+STRV_+" ? + /  128 +", u=1, v=1) Min_V = mt_luts( C, C, mode = "min", pixels = " 1 0 1 0 ", expr = "X Y  X Y  X Y  abs 1 + * X Y  abs 1 + "+STRV_+" 1 >= "+STRV_+" 0.5 ^ "+STRV_+" ? + /  128 +", u=1, v=1) MinMax_High_V = mt_lutXY( Max_V, Min_V, expr = "x 128  abs y 128  abs > x y ? 128  abs", u=1, v=1) MinMax_Low_V = mt_lutXY( Max_V, Min_V, expr = "x 128  abs y 128  abs > y x ? 128  abs", u=1, v=1) minmax_UL_V = mt_lutXY( MinMax_Low_V, MinMax_High_V, expr = "x y x  ", u=1, v=1) minmax_G_V = Average(MinMax_High_V, 0.1, MinMax_Low_V, 0.35, minmax_UL_V, 0.275, minmax_UL_V, 0.275) STRH_ = string(strh) Max_H = mt_luts( C, C, mode = "max", pixels = " 0 1 0 1 ", expr = "X Y  X Y  X Y  abs 1 + * X Y  abs 1 + "+STRH_+" 1 >= "+STRH_+" 0.5 ^ "+STRH_+" ? + /  128 +", u=1, v=1) Min_H = mt_luts( C, C, mode = "min", pixels = " 0 1 0 1 ", expr = "X Y  X Y  X Y  abs 1 + * X Y  abs 1 + "+STRH_+" 1 >= "+STRH_+" 0.5 ^ "+STRH_+" ? + /  128 +", u=1, v=1) MinMax_High_H = mt_lutXY( Max_H, Min_H, expr = "x 128  abs y 128  abs > x y ? 128  abs", u=1, v=1) MinMax_Low_H = mt_lutXY( Max_H, Min_H, expr = "x 128  abs y 128  abs > y x ? 128  abs", u=1, v=1) minmax_UL_H = mt_lutXY( MinMax_Low_H, MinMax_High_H, expr = "x y x  " ) minmax_G_H = Average(MinMax_High_H, 0.1, MinMax_Low_H, 0.35, minmax_UL_H, 0.275, minmax_UL_H, 0.275) Diff_V = mt_lutXY( Diff_V, minmax_G_V, expr = " x 128  y 1 > y 1 ? * y x 128  abs  1 > y x 128  abs  1 ? / 128 + ", u=1, v=1) Diff_H = mt_lutXY( Diff_H, minmax_G_H, expr = " x 128  y 1 > y 1 ? * y x 128  abs  1 > y x 128  abs  1 ? / 128 + ", u=1, v=1) Diff_HV = mt_adddiff(Diff_H, Diff_V) HPSharp = mt_adddiff(DeEmphasis, Diff_HV) rev_ = string(rev) reh_ = string(reh) ReEmphasis = HPSharp.Mt_Convolution(Horizontal=" 1 6 15 "+reh_+" 15 6 1 ", vertical =" 1 6 15 "+rev_+" 15 6 1 ", u=1, v=1) thrcv_ = string(thrcv) V = MT_Luts(ReEmphasis, ReEmphasis, mode="med", pixels = " 0 0 0 1 0 1 0 2 0 2 " ,expr = "X Y  X Y  X Y  abs 1 + * X Y  abs 1 + "+thrcv_+" 1 >= "+thrcv_+" 0.5 ^ "+thrcv_+" ? + /  128 +", u=1,v=1).mt_Lut("X 128  abs", u=1, v=1) thrch_ = string(thrch) H = MT_Luts(ReEmphasis, ReEmphasis, mode="med", pixels = " 0 0 1 0 1 0 2 0 2 0 " ,expr = "X Y  X Y  X Y  abs 1 + * X Y  abs 1 + "+thrch_+" 1 >= "+thrch_+" 0.5 ^ "+thrch_+" ? + /  128 +", u=1,v=1).mt_Lut("X 128  abs", u=1, v=1) Gauss_V = mt_Makediff(ReEmphasis, ReEmphasis.Mt_Convolution(Horizontal=" 1 ", vertical =" 1 6 15 20 15 6 1 ", u=1, v=1)) thr2gv_ = string(thr2gv) cstrv_ = string(cstrv) Gauss_V = mt_lutXY( Gauss_V, V, expr = " x 128  y * "+thr2gv_+" * "+cstrv_+" * 128 + ", u=1, v=1) Gauss_H = mt_Makediff(ReEmphasis, ReEmphasis.Mt_Convolution(Horizontal=" 1 6 15 20 15 6 1 ", vertical =" 1 ", u=1, v=1)) thr2gh_ = string(thr2gh) cstrh_ = string(cstrh) Gauss_H = mt_lutXY(Gauss_H, H, expr = " x 128  y * "+thr2gh_+" * "+cstrh_+" * 128 + ", u=1, v=1) Gauss_VH = mt_adddiff(Gauss_V, Gauss_H) contrast = mt_adddiff(ReEmphasis, Gauss_VH) Return(mergechroma(contrast, C, 1)) } Required Functions: Code:

Defaults are intended for strong sharpening on 2x upscaled material. For normal sharpening, set de to 0.02, str to 3 and cstr to 0.75 and go from there. The failure modes are as graceful as I can reasonably get them, considering the strength of the sharpening required. Also, the degree of sharpening that can be "gotten away with" varies pretty wildly by source. parameters: str = strength of highpass sharpening default 4 strv = vertical version of str defaults to str strh = horizontal version of str defaults to str de = deemphasis strength default 0.2 dev = vertical version of de defaults to de deh = horizontal version of de defaults to de re = reemphasis strength defaults to de/2 rev = vertical version of re defaults to re reh = horizontal version of re defaults to re cstr = strength of contrast sharpening default 1, values above 1 will cause halos cstrv = vertical version of cstr defaults to cstr cstrh = horizontal version of cstr defaults to cstr edit: thanks to Archimedes and Gavino for spotting two mistakes, both should now be fixed. edit2: Changed nonlinear lowpass function, new one should be generally more consistent Last edited by *.mp4 guy; 10th June 2010 at 23:47.

I always like your style, mp4 guy. Keep throwing luts at the problem, pare it down to what works, figure out why and use that to start the process again. I'll give this a shot tonight, though I have a feeling it's not going to work in realtime at all.

Edit: Here is a question in return. Is the reduction in sharpening strength good or bad in your opinion? Last edited by *.mp4 guy; 16th June 2010 at 06:34.

I mostly use sharpening in avsynth on upscaled still images via FritzPhoto, much like the examples you posted.
I found the lack of texture was a let down to be honest. Also it seem to overemphasize speckle like features and "stray pixels". But then it's remarkably immune to halos so I'll keep my eye on any developments.

Alright, new spin off function. Pretty much just a general purpose sharpener now, but imo better then medsharp or sssharp. Also, better name then blah.

Been testing Recon on a few web sized digicam and camera phone photos and I'm finding results are really pleasant and settings are simple and intuitive. I can see my self reachng for ReCon for most photos now. I'll still use lsfmod and sssharp for difficult sources and maximizing texture respectively. ReCon is in my eye the better general purpose sharpener now. Hats off for you *.mp4 guy!

Using a radius above 4 is not supported. If a radius above 4 is selected, mask generation is disabled (clip c is used instead). Radii above 4 are not supported because they become unusably slow, and the limiting method breaks down.
In this case, the blur is too much, and the limiting fails. In light of this I have added an unlimited mode, lmode=4, as upon further testing, the sharpening kernel performs better then unsharp masking on this source. try theses settings with the updated version: ReCon(rad=4, str=3, lmode=4) Also, let me restate, rads that are not equal to 0.5, 1, 1.5, 2, 2.5, 3 or 4 do not function properly.

I like the lmode range in the updated version !
I tried the blurry butterfly photo wih the new version was ab improvement. But I'm guessing you'd have to downscale that image further for a 4 pixel radius to fit.... Rather than talking about my special case I want to report that ReCon seems susceptible to alising in some sources, more so than lsfmod and sssharp.

However, on such blurred sources, antialiasing with supersampling afterwards (e. g. with NNEDI2) is not bad at all (if supersampling beforehand isn't a choice).

Instead of source > upsize > filter > downsize one would do 1) source > upsize > filter 2) get difference(upsize,filtered) 3) source.apply(difference.downsize) This way, the supersampling process affects only (well, mostly) the difference of the filter, not the source material in itself.

Things can be so easy. That will minimize the blur causing by the interpolation (up and downscaling), indeed. But that's not the fly in the ointment (© http://www.leo.org). It's much more the "difference.downsize" which I dislike in combination with normal sharpening.
