Abstract
A method for composite noise filtering is disclosed. The method generally includes the steps of (A) generating a selection value in response to a stationary check identifying one of a plurality of blendings for a current item of a current field, (B) generating a filtered item in response to one of (i) a first of the blendings between the current item and a first previous item co-located in a first previous field having an opposite phase of composite artifacts from the current field and (ii) a second of the blendings between the current item and a first motion compensated item from the first previous field and (C) switching between the first blending and the second blending in response to the selection value.
