  • Publication number: 20070070201
    Abstract: An object tracking apparatus includes a buffer unit that is configured to store picture information, an object position detecting unit that detects positional information of an object from the picture information, an object region detecting unit that detects a region of the object in the picture information based on the positional information, a storage unit that detects a feature properties of the object located in the region and stores the positional information, the feature properties and the region of the object, a predicting unit that predicts a position of the object of the next frame in the picture information from the position information, a determining unit that determines a predictive area of the next frame where the region is to be moved based on the position of the object of the next frame, and a verifying unit that verifies the feature properties of the object within the predictive area of the next frame and outputs a most resemble region.

  • Patent number: 5838828
    Abstract: A method and apparatus for motion estimation in a video signal includes an edge detector for generating present and reference binary edge bit maps and a binary block matcher for receiving the present and reference binary edge bit maps from the edge detector and for generating a motion vector for each of a plurality of blocks in the binary edge bit maps. By using binary edge bit map data to generate motion vectors, computational requirements are reduced. If the apparatus is provided as an integrated circuit, the technique of the present invention reduces cost, power requirements and size of the integrated circuit.

  • Patent number: 5790269
    Abstract: Edge or contour information is extracted from an image array by filtering and encoded. In order to improve reproduction accuracy, two separate filters are used to detect edge information. One of the filters detects "sharp" edges, or edges in which the discontinuity in pixel intensity values occurs over a range of a few pixels. The other filter detects "level" edges in which the pixel intensity value discontinuity occurs over a larger range of pixels than the "sharp" edges. The "smooth" areas between edges or contours are assumed to vary continuously between the contours, but for efficient implementation, a one-dimensional linear interpolation is used to regenerate the contour information between edges. In addition, to further improve performance, a line is fitted to the pixel intensity data. The end values of this line are then used for the pixel intensity data.

  • Patent number: 5403452
    Abstract: The invention relates to a method for determining the concentration of gases in a mixture of gasses by means of a gas sensor composed of three electrodes 1,2,3 and a solid electrolyte 4 upon the surface of which are secured the electrodes. A voltage Us being composed of a dc component Udc and an ac component Uac is applied to at least two electrodes, the measuring electrode 1 and the counter electrode 2. Us is controlled with reference to the reference electrode 3. The voltage components Udc and Uac of the voltage Us are chosen so that the metal salt formed by the ions of the solid electrolyte 4 with the gaseous components to be detected is again decomposed. The ion, current flowing between the electrodes is measured in dependence upon the voltage as applied. The concentration of the several gasses can be determined by known mathematical methods from the functional relation between the ion current and the voltage Us.
