    摘要: A subject captured by a camera may be affected by environmental lighting provided by nearby light sources and the sun or moon, which may cause underexposure or overexposure of the image or aesthetically displeasing color tones. Image processing and camera adjustments may mitigate some imaging problems with limited effect and introduce undesirable side effects. A lighting array may be devised to expose the subject to various types of light (e.g., white light comprising full spectrum illumination and red, green, and blue lights comprising partial spectrum illumination) to resolve lighting problems in a more effective manner. Moreover, the lighting array may be responsively controlled to adjust the subject image with respect to one or more target spectra specifying desirable colors for the subject image. The lighting array may be iteratively controlled, e.g. by a gradient descent algorithm, for incrementally adjusting parameters with respect to proximate target spectra for the image.

    摘要: Systems are disclosed that provide improved transfer speed of video data from a video capture device to a computing device using multiple video feeds respectively comprising different resolutions. A high-resolution image sensor is used to convert light images into a high-resolution video data stream. A down sampler converts the high-resolution video data stream to a low-resolution video data stream, so that both a low-resolution data stream and a high-resolution data stream are available. While the low resolution-data stream can be sent to the computing device, a digital signal processor (DSP) processes the high-resolution video data stream in accordance with an input control signal that is comprised of desired high-resolution video stream parameters derived from the low-resolution video data stream.

    摘要: A system that captures both whiteboard content and audio signals of a meeting using a digital camera and a microphone. The system can be retrofit to any existing whiteboard. It computes the time stamps of pen strokes on the whiteboard by analyzing the sequence of captured snapshots. It also automatically produces a set of key frames representing all the written content on the whiteboard before each erasure. The whiteboard content serves as a visual index to efficiently browse the audio meeting. The system not only captures the whiteboard content, but also helps the users to view and manage the captured meeting content efficiently and securely.

    摘要: A videoconferencing conferee may be provided with feedback on his or her location relative a local video camera by altering how remote videoconference video is displayed on a local videoconference display viewed by the conferee. The conferee's location may be tracked and the displayed remote video may be altered in accordance to the changing location of the conferee. The remote video may appear to move in directions mirroring movement of the conferee. This effect may be achieved by modeling the remote video as offset and behind a virtual portal corresponding to the display. The remote video may be displayed according to a view of the remote video through the virtual portal. As the conferee's position changes, the view through the portal changes, and the remote video changes accordingly.

    摘要: The system provides improved procedures to estimate head motion between two images of a face. Locations of a number of distinct facial features are identified in two images. The identified locations can correspond to the eye corners, mouth corners and nose tip. The locations are converted into as a set of physical face parameters based on the symmetry of the identified distinct facial features. The set of physical parameters reduces the number of unknowns as compared to the number of equations used to determine the unknowns. An initial head motion estimate is determined by: (a) estimating each of the set of physical parameters, (b) estimating a first head pose transform corresponding to the first image, and (c) estimating a second head pose transform corresponding to the second image.The head motion estimate can be incorporated into a feature matching algorithm to refine the head motion estimation and the physical facial parameters.In one implementation, an inequality constraint is placed on a particular physical parameter—such as a nose tip, such that the parameter is constrained within a predetermined minimum and maximum value. The inequality constraint is converted to an equality constraint by using a penalty function. Then, the inequality constraint is used during the initial head motion estimation to add additional robustness to the motion estimation.

    摘要: Videos are retargeted to a target display for viewing with little to no geometric distortion or video information loss. Salient regions of video frames may be determined using scale-space spatiotemporal information. Video information loss may be a result of spatial loss, due to cropping, and resolution loss, due to resizing. A desired cropping window may be determined using a coarse-to-fine searching strategy. Video frames may be cropped with a window that matches an aspect ratio of the target display, and resized isotropically to match a size of the target display.

    摘要: Described is a technology by which personal information that comes into a computer system is intelligently managed according to current state data including user presence and/or user attention data. Incoming information is processed against the state data to determine whether corresponding data is to be output, and if so, what output modality or modalities to use. For example, if a user is present and busy, a notification may be blocked or deferred to avoid disturbing the user. Cost analysis may be used to determine the cost of outputting the data. In addition to user state data, the importance of the information, other state data, the cost of converting data to another format for output (e.g., text-to-speech), and/or user preference data, may factor into the decision. The output data may be modified (e.g., audio made louder) based on a current output environment as determined via the state data.
