U S Philips Corporation, Michael E Marion, November 15, 1994: US05365280 (33 worldwide citation)

In a method of controlling a picture signal processing mode, first and second motion vectors are determined (ME, D.sub.T) for first and second fields, and a picture signal processing mode control signal is obtained by comparing (D.sub.T, -, COMP-R) the first and second motion vectors. The control si ...

In a method of measuring noise in image signals, a number of noise estimates (SAD) is calculated (1). Subsequently, it is determined (3-9) which noise estimation interval [A, B] out of a plurality of predetermined noise estimation intervals [A, B] contains at least a predetermined number of noise es ...

Olukayode A Ojo: Spatial noise reduction circuit and approach therefor. October 20, 2011: US20110255606-A1

Video data is processed according to grid-based characteristics. According to an example embodiment of the present invention, regions of an image centered on a horizontal and/or vertical grid are identified. For each of these regions, video data representing central sub-regions therein is filtered t ...
