<p>In a video noise reducer, the problem of noise at the edges of moving objects is dealt with by the introduction - into those regions - of spatial noise reduction. An adaptive low pass filter works especially well for spatial noise reduction, with adaption by reference to a dynamic noise measurement. Also, where pixel information is recursively filtered, with recursion being disabled at a disjuncture (caused by motion, panning, shot-change or otherwise), recursively filtered pixel information prior to a disjuncture continues to be output until pixel information following the disjuncture has been recursively filtered to an appropriate degree of noise reduction.</p> |
