Abstract: A set of electronic slide decks is searched using a target slide of a first electronic slide deck, each of the electronic slide decks containing a sequence of slides to be presented individually. A computer system receives from a user input individually selecting the target slide as a search input from the slides of the first electronic slide deck, compares the target slide with the slides of each electronic slide deck in the set to determine whether any of those slides matches the target slide, so as to determine, for each of the set of electronic slide decks, whether that electronic slide deck contains at least one slide that matches the target slide; and displays a set of search results in response to the user input, wherein each of the search results represents one of the electronic slide decks determined to contain at least one matching slide.

Abstract: A system is provided that allows a user to visualize data. A dataset that includes a plurality of data items arranged in a two-dimensional (2D) format is received. A request to visualize the dataset in three dimensions is then received. A three-dimensional (3D) visualization of the dataset is then generated based on this request. This 3D visualization adds a third dimension to the 2D arrangement of data items, where the extent of the third dimension is commensurate with the type and value of the data items. This 3D visualization includes an initial depiction of the dataset which is generated from a point of view that is specified by this request. The initial depiction of the dataset is then displayed on a display device of the system in lieu of the dataset itself.

Abstract: This disclosure relates to computer-implemented management of first and second electronic documents, each of containing a sequence of content components. A user interface displays a first sequence of display elements to represent the first electronic document, and a second sequence of display elements to represent the second electronic document. Each of the display elements in each of the displayed sequences represents an individual content component or group of content components of the electronic document represented by that sequence. The first and second sequences are displayed alongside each other, with their respective display elements in an initial alignment, to allow a side-by-side comparison of the electronic documents. The user can automatically realign the sequences to a selected content component.

Abstract: This disclose relates to computer-implemented management of an electronic slide deck, the electronic slide deck containing a set of slides to be presented individually.

Abstract: A flexible multi-layer sensing surface comprises a first flexible layer and a second flexible layer. The first flexible layer is a sensing layer and the second sensing layer is another sensing layer or an output layer. The sensing surface also comprises a calibration module which is configured to use the first flexible sensing layer to detect the relative position of the first and second flexible layers and this detected relative position is then used to update one or more stored operating parameters.

Abstract: Systems and methods for reducing interference between multiple infra-red depth cameras are described. In an embodiment, the system comprises multiple infra-red sources, each of which projects a structured light pattern into the environment. A controller is used to control the sources in order to reduce the interference caused by overlapping light patterns. Various methods are described including: cycling between the different sources, where the cycle used may be fixed or may change dynamically based on the scene detected using the cameras; setting the wavelength of each source so that overlapping patterns are at different wavelengths; moving source-camera pairs in independent motion patterns; and adjusting the shape of the projected light patterns to minimize overlap. These methods may also be combined in any way. In another embodiment, the system comprises a single source and a mirror system is used to cast the projected structured light pattern around the environment.

Abstract: A liftgate is provided with a modular sensor housing that spans a substantial portion of the width of the liftgate. The sensor housing has a plurality of rearward-facing apertures adapted to permit the cameras and/or proximity sensors from the vehicle to “see” through the housing. The sensor housing incorporates a plurality of sensor mounting brackets specifically adapted to the particular configuration of the vehicle sensors. The modular sensor housing enables a liftgate to be installed without disabling the rearview camera and proximity sensors.

Abstract: Foreground and background image segmentation is described. In an example, a seed region is selected in a foreground portion of an image, and a geodesic distance is calculated from each image element to the seed region. A subset of the image elements having a geodesic distance less than a threshold is determined, and this subset of image elements are labeled as foreground. In another example, an image element from an image showing at least a user, a foreground object in proximity to the user, and a background is applied to trained decision trees to obtain probabilities of the image element representing one of these items, and a corresponding classification assigned to the image element. This is repeated for each image element. Image elements classified as belonging to the user are labeled as foreground, and image elements classified as foreground objects or background are labeled as background.

Abstract: Real-time camera tracking using depth maps is described. In an embodiment depth map frames are captured by a mobile depth camera at over 20 frames per second and used to dynamically update in real-time a set of registration parameters which specify how the mobile depth camera has moved. In examples the real-time camera tracking output is used for computer game applications and robotics. In an example, an iterative closest point process is used with projective data association and a point-to-plane error metric in order to compute the updated registration parameters. In an example, a graphics processing unit (GPU) implementation is used to optimize the error metric in real-time. In some embodiments, a dense 3D model of the mobile camera environment is used.

Abstract: Generating computer models of 3D objects is described. In one example, depth images of an object captured by a substantially static depth camera are used to generate the model, which is stored in a memory device in a three-dimensional volume. Portions of the depth image determined to relate to the background are removed to leave a foreground depth image. The position and orientation of the object in the foreground depth image is tracked by comparison to a preceding depth image, and the foreground depth image is integrated into the volume by using the position and orientation to determine where to add data derived from the foreground depth image into the volume. In examples, the object is hand-rotated by a user before the depth camera. Hands that occlude the object are integrated out of the model as they do not move in sync with the object due to re-gripping.
