    摘要： A system helps filter and correct video captured and streamed from a mobile device. In particular, the system detects and streams content shown on screens, allowing anyone to stream screen content immediately without needing to develop hooks into external software (i.e. without installing a screen recorder software in the computer). The system can use a variety of user-selectable techniques to detect the screen, and utilizes the mobile device's touchscreen to allow users to manually override detected corners. However, some of these approaches could potentially be applied to other types of content, such as identifying TV screens, appliance LCD screens, other mobile devices' screens, multifunction devices. (e.g. a remote technician could help troubleshoot a malfunctioning MFD by having the end-user point his cellphone to the LCD screen of the MFD).

    摘要： Embodiments of the present invention include a video server that can detect and track the image of a pointing indicator in an input video stream representation of a computer display. The video server checks ordered frames of the video signal and determines movements for a pointing indicator such as a mouse arrow. Certain motions by the pointing indicator, such as lingering over a button or menu item or circling a button or menu item can provoke a control action on the server.

    摘要： A method for navigating instructional video presentations is disclosed. The method includes determining a pause mode of a video presentation, and playing the video presentation on a display device. The video presentation has one or more predetermined pause positions. The method also includes, while playing the video presentation, determining that the video presentation has reached one of the one or more pause positions. The method further includes, in accordance with a determination that the video presentation is in a first pause mode, pausing the video presentation at the one of the one or more pause positions and maintaining a display of a paused frame of the video presentation, and, in accordance with a determination that the video presentation is in a second pause mode distinct from the first pause mode, continuing to play the video presentation through the one of the one or more pause positions.

    摘要： Blogs (and other information sources) are recommended to a user based history of user's online activities. The system: (1) processes the user's web history, (2) identifies blog posts (and web pages) that link to pages read by the user, (3) generates multiple relevance scores for each identified post/page, and (4) produces multiple rankings of the corresponding source blogs (and web sites) by aggregating individual relevance scores (or combinations of relevance scores), according to users' preferences. The system allows the discovery of information sources that are likely to be interesting to the user and allows sources lost in the “long tail” to be seamlessly discovered.

    摘要： A system and method for identifying key frames of a presentation video that include stationary informational content. A sequence of frames is obtained from a presentation video and differences of pixel values between consecutive frames of the sequence of frames are computed. Sets of consecutive frames that are stationary are identified, wherein consecutive frames that are stationary have a proportion of changed pixel values below a first predetermined threshold, and wherein pixel values are deemed to be changed when the difference between the pixel values for corresponding pixels in consecutive frames exceeds a second predetermined threshold. Next, a set of key frames that include stationary informational content is retained. The set of key frames that include stationary informational content is then displayed for user interaction.
