It's one of the older filters taking from a nineties thesis. It cannot be
multithreaded because of the way it works, I'm afraid.

Erm, well, what is going on is that the filter in question is not
multithreaded, so it will always use only one of your cores. 

It looks to be a convolution-like filter, but it would need a closer look.
