  • Patent number: 7362351
    Abstract: A method and system for detecting an object in a zone located proximate to an interface between two liquid and/or gaseous media having different refractive indices, for example of the air/water type. The method and system produce at least a video image of the interface and the zone and produces electric signals representing each video image. Then, the electric signals are digitized and the data is processed by discriminating the data corresponding to the video image of the real object from those corresponding to the apparent video image generated by the interface.

  • Patent number: 7349475
    Abstract: A motion vector detection method includes extracting a first block from the m-th picture, extracting second blocks having a large correlation with respect to the first block from a (m+n)-th picture ((m+n)>m-th), detecting first motion vectors between the first and second blocks, extracting a third block located in spatially the same position as that of the first block from a (m+i)-th picture ((m+n)>(m+i)>m-th), computing second motion vectors of (n?1)/n times the first motion vectors, extracting a fourth block corresponding to a movement position of the third block from the (m+n)-th picture according to the second motion vector, and selecting an optimum motion vector maximizing a correlation between the third and fourth blocks from the first motion vectors.

  • Patent number: 7324592
    Abstract: A method acquires a plurality of input videos. The frames of each input video are acquired at a fixed sampling rate. Joint analysis is applied concurrently and in parallel to the input videos to determine a variable and non-uniform temporal sampling rate for each input video so that a combined distortion is minimized and a combined frame rate constraint is satisfied. Each input video is then sampled at the associated variable and non-uniform temporal sampling rate to produce output videos having variable temporal resolutions.

  • Patent number: 7310371
    Abstract: An apparatus comprising an output circuit, a first processing circuit and a second processing circuit. The output circuit may be configured to generate an output data stream in response to (i) a first intermediate signal, (ii) a second intermediate signal, and (iii) a third intermediate signal. The first processing circuit may be configured to generate the first intermediate signal in response to (i) a processed video signal and (ii) a prediction flag. The second processing circuit may be configured to generate (i) the processed video signal, (ii) the second intermediate signal and (iii) the third intermediate signal in response to an input video signal.
