  • Publication number: 20080013784
    Abstract: A path connecting a target sample of an arbitrary N-dimensional vector to a plurality of candidate samples in a sample set in an N-dimensional space having ?-dimensional positions and an ?-dimensional feature quantity is set. On the path, the feature quantity is integrated to obtain an integration value. Using the integration value as a variable value of a preset kernel function, a kernel function value corresponding to the target sample is calculated.

  • Patent number: 7298911
    Abstract: A video encoding apparatus is provided with a resolution converting section, an encoding section, and a transmitting section. The resolution converting section enlarges or reduces a binary picture which represents the shape of an object. The encoding section encodes a binary picture reduced by the resolution converting section. The reduction ratio used by the resolution converting section is encoded, and the transmitting section transmits this encoded reduction ratio along with encoded data on the binary picture. The amount of encoded data produced from the encoding section is controlled by changing the enlargement/reduction ratio used by the resolution converting section.
