摘要： A method of image reconstruction is provided. The method includes capturing a stereoscopic pair of images of a scene, generating a disparity map for the pair of images, and defining a series of value ranges corresponding to disparity with each value range in the series having an end point corresponding to a greater disparity than an end point of preceding value ranges in the series. For each value range in the series, and progressing in order through the series from the first value range in the series, the method includes selecting points in the disparity map falling within the respective value range and generating a mesh responsive to those selected points. The method also includes subsequently merging the series of generated meshes to form a 3D model of the scene.

摘要： A method of rendering an image based upon a first stereoscopic image comprising a pair of images is provided. The method includes generating a virtual three-dimensional model of the scene depicted in the first stereoscopic image responsive to distances derived from the first stereoscopic image, detecting one or more free edges in the three dimensional model, and generating one or more textures for the virtual three-dimensional model from at least one of the pair of images of the first stereoscopic image. The method also includes applying at least one texture to a respective part of the three dimensional model, and rendering the virtual three dimensional model from a different viewpoint to that of the first stereoscopic image. Rendering the virtual three dimensional model comprises modifying a transparency of rendered pixels of an applied texture as a function of the pixel's distance from that free edge.

摘要： A display is disclosed that comprises an array of display pixels, in which light sensing pixels are interspersed with the display pixels substantially across the area of the display. At least one colour display sub-pixel is arranged to be switched off when the corresponding colour light sensor pixel closest to that display sub-pixel is detecting light to generate an image. A portable electronic device is disclosed which comprises the display. The display is then operable to capture an image from the light sensing pixels, so that for example it can then operate as one or more of a digital mirror, scanner, biometric lock or touch panel. When a user looks at the display for a video call, the captured image of the user appears to look directly the other party.

摘要： An entertainment device comprises an input, a marker detector and a failure boundary calculation processor. The input is operable to receive a captured image from a video camera. The marker detector is operable to detect a fiduciary marker within the captured image, and is also operable to estimate a distance and angle of the fiduciary marker. The failure boundary calculation processor is operable to calculate at least one of an additional distance and an additional angle from the currently estimated distance and angle of the fiduciary marker at which recognition of the fiduciary marker is assumed to fail.

摘要： A head-mountable display system comprises a head mountable display having a frame to be mounted onto an observer's head, the frame defining one or two eye display positions which, in use, are positioned for viewing by the observer. The frame comprises one or more shutters for obscuring the observer's view of the surrounding real environment and a display element mounted with respect to each of the eye display positions. The display element provides a virtual image of a video display of a video signal from a video signal source to the observer. An object detector detects the presence of an object within a detection range of the observer's head. And a controller controls operation of the head mountable display so as to allow the observer to view at least a portion of the surrounding real environment in response to detection of the presence of an object within the detection range.

摘要： A head-mountable display system comprises a frame to be mounted onto an observer's head. The frame defines one or two eye display positions for positioning in front of a respective eye of the observer. A display element is mounted with respect to each of the eye display positions, and provides a virtual image of a video display of a video signal from a video signal source to that eye of the observer. A motion detector detects motion of the observer's head. A high-pass filter is arranged to generate higher frequency and lower frequency components of the detected motion, according to a threshold frequency associated with the response of the high-pass filter. And a controller controls the display of the video signal based upon the detected motion, to compensate for the higher frequency component of motion by moving the displayed image in an opposite direction to that of the detected motion.

摘要： A method captures a video image frame of a book, estimates a position of at least a first endpoint of the book's spine, applies an edge detection operation to the video image frame to generate an edge image, applies a Hough transform to a first region in the edge image to obtain a plurality of line estimates, and rejects line estimates that do not substantially intersect with an estimated endpoint of the book's spine. For line estimates that are not rejected, detecting one or more clusters of angles of the line estimates with respect to an estimated endpoint of the book's spine, and generating an average angle from the cluster of angles. An average angle is selected, and an angular position of the turning leaf in the book's image responsive to the currently selected average angle is estimated.

摘要： A method of augmented reality interaction for repositioning a virtual object on an image of a surface comprises capturing successive video images of the surface and first and second control objects and defining an interaction start area over the surface with respect to the virtual object. The method detects the control objects in successive video images, detects whether the control objects are brought together over the interaction start area, and if so, analyses a region of successive video images using optical flow analysis to determine the overall direction of motion of the control objects and augmenting the video image to show the virtual object being held by the control objects. Augmenting the video image itself comprises superposing a graphical effect on the video image prior to superposition of the virtual object, such that the graphical effect visually disconnects the virtual object from the video image in the resulting augmented image.

摘要： A method of assisting a first player of a videogame is provided. The method includes making a game state of the first player accessible to a second player. The game state describes a state of the videogame as played by the first player. The method also includes executing the videogame for the second player using the game state of the first player to define the initial state of the videogame for the second player, allowing the second player to play the videogame based upon the game state of the first player until a first predetermined criterion is met, and providing to the first player data for updating their game state in response to the play of the second player.
