摘要： A method of augmenting a video image comprises the steps of estimating the extent of an identified surface captured within the video image and identifying skin pixels within a test area corresponding to the estimated extent of the identified surface within the video image. The method also includes extrapolating positions for skin pixels within the video image that are outside the estimated extent of the identified surface based upon the identified skin pixels, generating a mask from a combination of identified skin pixels and extrapolated skin pixels, and setting an extent of a computer graphic to be superposed substantially on top of the identified surface within the video image. The extent is greater than the estimated extent of the identified surface. The method further includes superposing the graphical augmentation of the video image responsive to the generated mask.

摘要： Graphics processing systems and methods are disclosed which may minimize invocations to a pixel shader in order to improve efficiency in a rendering pipeline. In implementations of the present disclosure, a plurality of samples within a pixel may be covered by a primitive. The plurality of samples may include one or more color samples and a plurality of depth samples. The nature of the samples which were covered by the primitive may be taken into account before invoking a pixel shader to perform shading computations on the pixel. In implementations of the present disclosure, if at least one sample is covered by a primitive, but none of the samples are color samples, an invocation to a pixel shader may be avoided.

摘要： A method of processing an input image representing at least a part-spherical panoramic view with respect to a primary image viewpoint comprises mapping regions of the input image to regions of a planar image according to a mapping which varies according to latitude within the input image relative to a horizontal reference plane so that a ratio of the number of pixels in an image region in the input image to the number of pixels in the image region in the planar image to which that image region in the input image is mapped, generally increases with increasing latitude from the horizontal reference plane.

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 head-mountable display (HMD) comprises a frame for mounting on a user's head, a camera mounted on the frame for capturing a view of the user's eyes, a motion detector for detecting motion of the HMD and for generating a motion signal representing a movement of the HMD with respect to time, and a controller. The controller estimates a distance between the user's eyes by capturing a relative separation of the user's eyes from an image of the user's eyes captured by the camera at a start position. The controller processes a motion period of the motion signal, and estimates a displacement of the user's eyes with respect to the frame. The HMD can adjust a relative position at which a first image is displayed to one eye and position at which a second image is displayed to the other eye for an improved viewing experience.

摘要： A server for administering an on-line virtual environment comprises a data communication arrangement and a processor. The data communication arrangement receives a signal from a first entertainment device in communication with an instance of the virtual environment. The signal indicates that a user of that device has performed a predetermined action. The processor determines the availability of a second entertainment device, and is operable to switch the second device from a second instance of the virtual environment to the first instance of the virtual environment. The data communication arrangement is operable, if the second device is available, to transmit a signal to the first device indicating that a software controlled avatar within that instance should change modes to represent a user of the second device. The processor is operable to transfer control of a previously software controlled avatar within that instance of the virtual environment to the second device.
