"Denosie"+"sharpen"+"stabilization"

[Nephilis]

I want to continue from here about "Denosie+sharpen" stabilization topic in this thread (http://forum.doom9.org/showthread.php?p=1254768#post1254768)

i want to add two Screenshots

After Denoise and Sharpen
http://img6.imageshack.us/img6/2254/ss1x.png

My first point was denoising without removing the details and a stabilized denoise and sharpen..

Opinions about the SS ? Or any suggestions ?

Thanks in advance..

I would actually scale the sharpening down a bit. It's starting to look a little too fake.

Yeah, his face has become plastic looking :)

What sharpener did you use?

[Betsy25]

That looks like a very good sharpening technique to me :)

Care to share what script you used for that ? :thanks:

[Nephilis]

~MiSfit

Not only one sharpen filter, i used a sharpen filter combo and many filters too..

Are those faces become plastic looking too, in your opinion?

No, to be honest, they look fantastic ! :o

[Sagekilla]

He seems to refer to this technique:


src = last
shrp = src.enhance(sharpness)

src_super = src.MSuper()
shrp_super = shrp.MSuper(levels=1)

bv2 = MAnalyse(src_super, isb=true, delta=2, overlap=4)
bv1 = MAnalyse(src_super, isb=true, delta=1, overlap=4)
fv1 = MAnalyse(src_super, isb=false, delta=1, overlap=4)
fv2 = MAnalyse(src_super, isb=false, delta=2, overlap=4)

src.MDegrain2(shrp_super, bv1,fv1,bv2,fv2,thSAD=??)

I think it looks good for the most part, but there is some weird looking splotchy grain in the 3rd pic (2nd set) to the right of his face

Can you post the source pics for the 2nd set?

[Sagekilla]

Here's another rudimentary example of what Didee posted earlier. Note I only used a naive Sharpen(1). Sometimes, it's good to use a dumb sharpener and then let motion-compensated averaging like MDegrain handle the rest ;)




src = last
sharp = src.Sharpen(1)
src_super = src.MSuper(pel=2)
sharp_super = sharp.MSuper(pel=2, levels=1)

bvec3 = src_super.MAnalyse(isb=true, delta=3, overlap=4)
bvec2 = src_super.MAnalyse(isb=true, delta=2, overlap=4)
bvec1 = src_super.MAnalyse(isb=true, delta=1, overlap=4)
fvec1 = src_super.MAnalyse(isb=false, delta=1, overlap=4)
fvec2 = src_super.MAnalyse(isb=false, delta=2, overlap=4)
fvec3 = src_super.MAnalyse(isb=false, delta=3, overlap=4)

stable = src.MDegrain3(sharp_super, bvec1, fvec1, bvec2, fvec2, bvec3, fvec3)


Interleave(src, stable, sharp)

Dumb Sharpened

Next set of images, I merged the chroma back from the source image into the sharpened image. Doing a dumb Sharpen(1).Sharpen(0.3) in this example amplified the chroma noise -excessively- to the point that even MDegrain3 had trouble handling it nicely.

I can't even play with these filters, MPC HC completely stalls and keeps at the same frame for like a full minute !:eek:

Seems like the stable is too much for my Core2 Duo 2.6Ghz

[Sagekilla]

What, are you trying to do this in real time or something? The filter chain I posted isn't meant for real time processing at all. If you want that, do this:


src = last
sharp = src.Sharpen(1)

src_super = src.MSuper()
sharp_super = sharp.Msuper(levels=1)

bvec = src_super.MAnalyse(blksize=16, isb=true, search=2)
fvec = src_super.MAnalyse(blksize=16, isb=false, search=2)
src.MDegrain1(sharp_super, bvec, fvec)

Oops ! :o

Another thing learned !:p

[Sagekilla]

MVTools isn't designed to be used in real time. It can be used in real time if you tweak it right, but it's usually used for doing very high quality MC.
