View Full Version : Arbitrary Median Filter

02 February 2007, 12:15 PM
I finally did a screen capture of an Arbitrary Input Median Filter.

So in laymen's terms, what is that?

Basically with a still camera, it removes moving stuff.
(There are a lot more applications, but this is the one I did my demo on)

So I produced a simple video of me using the tool on some popular footage, and I was curious to know if anyone else uses either Temporal Median Filters, or something else that does the same sort of thing.

I wrote this node in C++ and on a fairly humble Macintosh, it'll work through a 10 frame sampling in about a second. I used a fairly simple sort algorithm since the gains over such small amount of frames that I'm sampling (usually between 5 and 15) don't give much of an increase (at least to warrent the extra programming time).
(I hope no one minds that I used youtube to save bandwidth)

Furnace comes with a tool called "rig removal" that does something similar.
