A first image of both of the first and second foreground objects is acquired whilst the first foreground object emits electromagnetic radiation with the first spectral power distribution. A second image of the first and second foreground objects is acquired whilst the first foreground object is not emitting electromagnetic radiation or is emitting electromagnetic radiation with a second spectral power distribution which is different to the first spectral power distribution. An alpha matte of the first and second foreground objects is generated based on a comparison of the first image and second image. | 04-28-2011 |

20120207359 | Image Registration - Image registration is described. In an embodiment an image registration system executes automatic registration of images, for example medical images. In an example, semantic information is computed for each of the images to be registered comprising information about the types of objects in the images and the certainty of that information. In an example a mapping is found to register the images which takes into account the intensities of the image elements as well as the semantic information in a manner which is weighted by the certainty of that semantic information. For example, the semantic information is computed by estimating posterior distributions for the locations of anatomical structures by using a regression forest and transforming the posterior distributions into a probability map. In an example the mapping is found as a global point of inflection of an energy function, the energy function having a term related to the semantic information. | 08-16-2012 |
20120269407 | AUTOMATIC ORGAN LOCALIZATION - Automatic organ localization is described. In an example, an organ in a medical image is localized using one or more trained regression trees. Each image element of the medical image is applied to the trained regression trees to compute probability distributions that relate to a distance from each image element to the organ. At least a subset of the probability distributions are selected and aggregated to calculate a localization estimate for the organ. In another example, the regression trees are trained using training images having a predefined organ location. At each node of the tree, test parameters are generated that determine which subsequent node each training image element is passed to. This is repeated until each image element reaches a leaf node of the tree. A probability distribution is generated and stored at each leaf node, based on the distance from the leaf node's image elements to the organ. | 10-25-2012 |

20100034132 | TELECOMMUNICATIONS SYSTEM AND METHOD - A telecommunications system for communicating data to and from a mobile device. The system comprises a plurality of repeater nodes disposed to form a network. Each repeater, node has a transceiver unit operable to transmit the data with a first transmission power to one or more other of the repeater nodes within one of a plurality of slots of a time frame. Each repeater node is allocated a time slot, and the mobile device is arranged to transmit and receive data to and from the repeater nodes in the network. Each of the repeater nodes is operable to transmit a pilot signal during the same one of the time slots of the time frame with a second transmission power, the second power being less than the first transmission power. The pilot signal includes an identifier of the repeater node which is transmitted with the pilot signal and the mobile device is operable to receive one of the pilot signals. | 02-11-2010 |

20100302993 | TELECOMMUNICATIONS SYSTEM AND METHOD - A telecommunications system, for communicating data to and from a mobile device. The system comprises a plurality of repeater nodes, each repeater node having a transceiver unit operable to transmit and receive data to or from one or more other of the repeater nodes or the control node or the mobile device within a predetermined range, and processing unit operable to control the transceiver unit. The system also comprises a control node operable to transmit data in a downstream direction from the control node to the mobile device via the repeater nodes and to receive data from the mobile device transmitted in an upstream direction from the mobile device to the control node via the repeater nodes. The control node, the mobile device and the plurality of repeater nodes are arranged to communicate the data in the downstream direction from the control node to the mobile device via the repeater nodes using a time frame divided into a plurality of time slots, and to communicate the data in the upstream direction from the mobile device to the control node via the repeater nodes using the time frame, and the time slots of the time frame are allocated to the repeater nodes to the effect that each repeater nodes transmits to another repeater node in one of the upstream or the downstream directions in a time slot which is a minimal time from the time slot in which the other repeater node transmits in the upstream or downstream direction. The telecommunications system reduces the time taken for upstream or downstream data to be transmitted from a mobile terminal within the network, via the repeater nodes to the control node. | 12-02-2010 |

20090198676 | Indexing Documents for Information Retrieval - Information retrieval systems such as web search systems locate documents amongst millions and even billions of possible documents on the basis of query terms. In order to achieve this document indexes are created. We propose creating new fields in the documents to store feedback information. This information comprises query terms used in a particular search as well as information about whether a particular document retrieved is given positive or negative feedback for example. Indexes are created on the basis of this feedback information in addition to other available information. As a result relevance of search results is improved. Multiple fields of information are available for given documents (such as abstract fields, title fields, anchor text fields as well as our feedback fields). Any search algorithm which deals with multiple fields as well as multiple query terms and which provides for differential weighting of document fields is used. | 08-06-2009 |
