Abstract:
Embodiments of the present invention are directed to a system and method for recursive noise reduction. An exemplary method comprises receiving a first film frame having a first frame rate and a second film frame having the first frame rate and converting the first film frame into a first plurality of video frames having a second frame rate. The exemplary method further comprises converting the second film frame into a second plurality of video frames having the second frame rate, wherein the first plurality of video frames is positioned adjacent the second plurality of video frames at a border between the first plurality of video frames and the second plurality of video frames and updating a noise reduction correction signal only on the border between the first plurality of video frames and the second plurality of video frames when operating in a first mode.
