denoiser comparison for analogue caps
Ivo (i4004) and I, finally finished our denoiser comparison for analogue captures!
The comparison can be found here: http://www.geocities.com/wilbertdijk...comparison.htm A summary of the conclusions: Quote:
1) Images can be downloaded separately (see introduction), if the site loads too slow. 2) If someone knows how to simplify/improve the javascript, please let us know. |

Thanks!
@Fizick, I stripped out the large bmp pictures (from the raw XviD animation): http://www.geocities.com/wilbertdijk...log_simple.zip It's 1.11 MB. |

Can I consider these tests valid on anime analog material too?

Fizick's FFT3DFilter
@Wilbert,
Fizick's FFT3DFilter (Version 1.3 - July 20, 2005) has reached a point where it may be better at denoising and preserving detail than PixieDust: http://forum.doom9.org/showthread.ph...122#post689122 Since your comparison results are "based on our visual inspection", would you & Ivo (i4004) be willing to put this filter through your test?

Once I have played with PeachSmoother (suppose to be useful for any filter with startup delay), I used a trick with extra added first n-frame part of movie.
After processing the movie I have trimmed this extra leading part away.

@North2Polaris
It's been a long time since they did that test... Quote:
_____________________________ Back in December '03 when I was a total newbie playing with videos (and not just a semi-newbie like now!) I sifted these forums for all the denoising advice and scripts I could get, and then spent about a fortnight comparing them against each other split-screen using the CompareVersions script I posted elsewhere... about 20-25 different filters IIRC; I ended up deciding that there were plenty of contenders on still scenes but the Dust filters were the only ones I was happy with on motion scenes. I remember being pretty happy on finding this thread and seeing that people who knew about video had reached the same conclusion. But about a year or so later it seemed, at least to me, that the ground rules had changed completely... there were sufficiently good motion estimation + compensation tools out there (MVTools) that all the denoising filters would have to be tested against Dust again but this time with a motion compensation forward/back frames interleaved in.
