Dotkill - spatial dotcrawl remover

This is a new year's eve bonus from my small collection of unfinished things.

It's a filter doodle that's been sitting around for a long time without making more progress. It's a pure spatial dotcrawl remover that works after field matching or on progressive input. It generally doesn't artifact much and when it does it's rarely worse than the original dotcrawl anyway.

core.dotkill.DotKill(clip[, napply=1, ignorematch=False])
clip = core.vivtc.VFM(clip, order=1)
clip = core.dotkill.DotKill(clip, napply=1)
clip = core.vivtc.VDecimate(clip)

This filter should be placed AFTER field matching with VFM if field matching is needed. The napply setting is how many times to apply the filter, values between 1 and 4 are generally sane. The higher you go the bigger chance of artifacting. The ignorematch argument is only for testing purposes and should probably never be touched.

It will most likely perform very poorly on purely interlaced content.

The plan is still to add temporal filtering some day but don't expect it anytime soon.

And don't forget to support the projects you like. Especially the ones where you don't have to donate before you can try it.
