    摘要: Disclosed are embodiments of systems and methods for synthesizing a detailed depth map from a video image. In embodiments, the motion vectors decoded from a video stream may be classified into groups by the application of K-Model clustering techniques based on an affine model. In embodiments, a coarse depth map of the image pixels may be generated using the image segmented according to the motion vector clusters. In embodiments, high resolution gradient maps of the image may be generated using the coarse depth map as well as edge information from the image. In embodiments, a surface reconstruction algorithm, such as the Frankot-Chellappa algorithm, may be applied to the high resolution gradient maps to synthesize a detailed depth map of the image. A detailed depth map of an image may be used to render a three-dimensional surface, for example.

    摘要: Disclosed are embodiments of systems and methods for identifying features using color information in an image. The image may be formed from one or more display images comprising color information and features or feature components. Because color information may be used to identify features, more than one feature or feature component may be displayed in a display image. Because a plurality of features may be identified in a calibration image, an image system, such as a projector-camera system, can reduce the number of display images needed to calibrate the system.

    摘要: A method for presentation interaction. The method includes, receiving by a computer system an indication of a manual selection of a region proximate to an audience member of an audience wherein the indication is received via an interaction with a displayed image of the audience. The method also includes utilizing a microphone array communicatively coupled with a beam-forming component of the computer system to focus audio pickup from the region proximate to the audience member in response to receiving the indication. The method also includes displaying an enhanced image of the region proximate to the audience member using the computer system in response to receiving the indication.

    摘要: Disclosed herein are multimedia-conferencing systems and methods enabling local participants to hear remote participants from the direction the remote participants are rendered on a display. In one aspect, a method includes a computing device receives a remote participant's image and sound information collected at a remote site. The remote participant's image is rendered on a display at a local site. When the local participant is in close proximity to the display, sounds generated by the remote participant are played over stereo loudspeakers so that the local participant perceives the sounds as emanating from the remote participant's location rendered on the display.

    摘要: A method for processing video using depth sensor information, comprising the steps of: dividing the image area into a number of bins roughly equal to the depth sensor resolution, with each bin corresponding to a number of adjacent image pixels; adding each depth measurement to the bin representing the portion of the image area to which the depth measurement corresponds; averaging the value of the depth measurement for each bin to determine a single average value for each bin; and applying a threshold to each bin of the registered depth map to produce a threshold image.

    摘要: Light distortion due to light noise or light scattering object in the path of a light beam from a projector to a camera's image sensor in projector-camera systems are mitigated, or eliminated, by a simple modification to a light transport matrix T. For each row in light transport matrix T, matrix entries along a common row are compared, and all but the highest valued entry in the row are zeroed out, i.e. nullified. It is preferred that an array and record notation be used in order to reduce the size of the light transport matrix T, and its modified version to two arrays.
