Mcneeley David Lowell, Fling Russell Thomas: Adjustable antialias filters.. Rca Licensing, August 1, 1990: EP0380351-A2 (102 worldwide citation)

A programmable sampled data subsampling system includes a programmable antialias filter which bandlimlts the information bandwidth of the signal to be subsampled in accordance with the subsampling rate. The antialias filter includes a recursive filter which scales and combines (304,306,308) input sa ...

Andrew Derek, Morris Octavius John: Motion vector estimation, motion picture encoding and storage.. Philips Electronics, Philips, April 7, 1993: EP0535746-A2 (79 worldwide citation)

In the encoding of a frame (P3) in a digitised motion picture sequence, the frame is divided into blocks (A) of pixels and a motion vector (VA) found to predicts the contents of each block A from a block (A') in a previous frame (IO). Rather than evaluate many thousands of candidate vectors to find ...

A system for generating a digest of a moving image according to the present invention includes: a generating section for generating a moving image having a plurality of frames, and for generating an operation signal in response to an input received by the generating section during the generating of ...

Lo Muzio Pierluigi: Recursive video signal processor.. Philips, Philips, August 11, 1993: EP0554586-A2 (39 worldwide citation)

To be able to cope with the high video signal data rates which occur in a high definition video signal, a recursive video signal processor for estimating motion vectors demultiplexes the incoming video signal into four adjacent quadrants which are each processed by four separate motion estimators. T ...
