Method for efficient coding of shape descriptor parameters |
November 4, 2008 |
| A method of representing an object appearing in a still or video image, by processing signals corresponding to the image, comprises deriving a plurality of sets of co-ordinate values representing the shape of the object and quantising the co-ordinate values to derive a coded represen |

Method and apparatus for representing and searching for an object in an image |
June 17, 2008 |
| A method representing an object appearing in still or video image for use in searching, wherein the object appears in the image with a first two-dimensional outline, by processing signals corresponding to the image, comprises deriving a view descriptor of the first outline of the obj |

Method and apparatus for representing and searching for an object using shape |
April 22, 2008 |
| A method is disclosed for representing a sequence of images constituting a moving image by processing signals corresponding to the image. An object appearing in one image is identified in the sequence in a first perspective view, and the same object appearing in another image is iden |

Determining statistical descriptors of a signal from a set of its samples |
April 1, 2008 |
| An entity is subjected to an interrogating signal, and the reflection from the entity is repeatedly sampled to obtain a first set of values each dependent on the intensity of the reflected signal. A logarithmic transformation is applied to the sample values to obtain a second set of |

Method for efficient coding of shape descriptor parameters |
January 22, 2008 |
| A method of representing an object appearing in a still or video image, by processing signals corresponding to the image, comprises deriving a plurality of sets of co-ordinate values representing the shape of the object and quantizing the co-ordinate values to derive a coded represen |

Method and apparatus for representing and searching for an object in an image |
September 11, 2007 |
| A method of representing an object appearing in an image, the method comprising deriving a plurality of view descriptors of the object, each view descriptor corresponding to a different view of the object, and associating the two or more view descriptors, the method comprising indica |

Method and apparatus for detecting and/or tracking one or more colour regions in an image or seq |
June 26, 2007 |
| A method of detecting a region having predetermined colour characteristics in an image comprises transforming colour values of pixels in the image from a first colour space to a second colour space, using the colour values in the second colour space to determine probability values ex |

Hough transform based method of estimating parameters |
March 12, 2002 |
| A Hough transform based method of estimating N parameters a=(a.sub.1, . . . , a.sub.N) of motion of a region Y in a first image to a following image, the first and following images represented, in a first spatial resolution, by intensities at pixels having coordinates in a coordinate sys |
