What order for this filters?

[E-Male]

I´m testing some filters on dvd´s with some noise
------
crop
lanczosresize
convolution3d
msharpen
------
what order would you recommend for these filters for best quality (speed doesn´t matter)?

thx

Well if speed isn't a problem i would convolution before resize,so the lanczos resize would sharpen the image,after conv3d had blurred it.But if you are using msharpen i guess you could do it with that.
So the order would be

crop
lanczosresize
convolution3d
msharpen

i think :)

If speed doesn't matter I would recommend :

Crop
Convolution3D
LanczosResize
MSharpen

thx

i forgot one: sandwich (if the new version works without visible errors)
using this one before convolution3d could reduce some noise without too bad sideeffects and make it possible to use convolution3d with lower settings

---
crop
sandwich
lanczosresize
convolution3d
msharpen
---

sandwich should be before resizing to have the original pixels, msharpen should be last and croping first ofcourse
the only question is
lanczosresize <-> convolution3d ??
i gues thats where people should tell me to test it myself, i´ll do that :) , but if you got any more ideas, please post

Hi there.

I think it is generally accepted that any sharpening should be done after the resize, as the interpolation/calculations involved in this would destroy (blur) the effect. Having said that i currently use UNFILTER imediately after conv3d and before resize - i figure that it slightly reverses any bluring that may have come from c3d, with the final pin-sharpening done by MSHARPEN at the end. So -


Crop

Convolution3D
unfilter

.
LanczosResize
MSharpen


Hope this is useful.
