TTempSmooth

The TTempSmooth filter was designed to be a motion adaptive (only works on stationary parts of the picture), temporal smoothing filter aimed at preventing as many artifacts as possible at given lthresh and cthresh settings.
To do this it processes luma/chroma together when checking for pixel similarity and processes out from the current center frame continuously checking difference to the center frame pixel as well as to the previous frame pixel. Its averaging method allows it to create stable images and makes it very good at removing grain in stationary areas.
The filter includes TTempSmooth, the original version that uses an inverse difference weighting system, as well as TTempSmoothF, which is a faster version (40-50%) that is a special case of TTempSmooth with lmdiff/cmdiff set equal to or greater than lthresh/cthresh.
