摘要： An image rendition and capture method includes rendering a first image on a surface using a first set of wavelength ranges of light. While the first image is being rendered, a second image is captured using a second set of wavelength ranges of light but not the first set. The second image is of the surface on which the first image is being rendered.
摘要翻译：图像再现和捕获方法包括使用第一组波长范围的光在表面上渲染第一图像。当第一个图像被渲染时，使用第二组光的波长范围而不是第一组拍摄第二个图像。第二个图像是第一个图像被渲染的表面。

摘要： Embodiments of the present invention are directed to a visual-collaborative system enabling geographically distributed groups to engage in face-to-face, interactive collaborative video conferences. In one aspect, a visual-collaborative system comprises a display screen, a camera system, and a projector. The display screen has a first surface and a second surface, and the camera system is positioned to capture images of objects through the display screen. The projector is positioned to project images onto a projection surface of the display screen, wherein the projected images can be observed by viewing the second surface. The system includes a first filter disposed between the camera and the first surface, where the first filter passes light receives by the camera but substantially blocks the light that is produced by the projector.

摘要： A video sequence control system that includes an input video frame buffer and an output video frame selection component is described. The input video frame buffer receives input video frames from a video source. The output video frame selection component determines the video frame to be output according to a scheduler that provides timing information and modulation information. The timing information includes information regarding when a video frame will be output. The modulation information varies dependent upon the frame types available to be output, wherein the available frame types include at least image frames from the input video frame buffer and functional frames, wherein the at least image frames and functional frames are output according to a pattern defined by the scheduler. In addition based on the timing information, a synchronization output signal is output corresponding to the output of the functional frame.

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.
摘要翻译：一种使用深度传感器信息处理视频的方法，包括以下步骤：将图像区域划分成大致等于深度传感器分辨率的多个条带，每个仓对应于多个相邻图像像素; 将每个深度测量添加到表示深度测量对应的图像区域的部分的bin; 平均每个仓的深度测量值，以确定每个仓的单个平均值; 以及对所登记的深度图的每个仓应用阈值以产生阈值图像。
