摘要： A framework for facilitating collaborative interaction between users of a web application is presented. The framework provides persistence and sharing mechanisms for arbitrary application-defined objects. The sharing mechanism is coupled with a consistency mechanism that keeps client states consistent even when users perform conflicting operations. This framework is application-independent in that the persistence, sharing between clients and maintaining a consistent state among the clients is accomplished without the need for specific knowledge of the design of the web application. Thus, web developers can focus on the logic of the application and the UI, instead of spending time designing and implementing collaborative capabilities.
摘要翻译：介绍了一种用于促进Web应用程序用户之间的协作交互的框架。该框架为任意应用程序定义的对象提供持久性和共享机制。共享机制与一致性机制相结合，即使在用户执行冲突操作时也能保持客户端状态的一致性。该框架是独立于应用程序的，因为在客户机之间的持久性，共享和维护一致的状态之间完成了这一任务，而不需要Web应用程序设计的特定知识。因此，Web开发人员可以专注于应用程序和UI的逻辑，而不是花时间设计和实现协作功能。

摘要： A system and process for improving the appearance of improperly colored and/or improperly exposed images is presented. This involves the use of two novel techniques—namely an automatic color correction technique and an automatic exposure correction technique. The automatic color correction technique takes information from within an image to determine true color characteristics, and improves the color in improperly colored pixels. The automatic exposure correction technique measures the average intensity of all of the pixels and adjusts the entire image pixel by pixel to compensate for over or under exposure. These techniques are stand alone in that each can be applied to an image exclusive of the other, or they can both be applied in any order desired.
摘要翻译：提出了一种用于改善不正确着色和/或曝光不正确的图像外观的系统和过程。这涉及使用两种新颖的技术 - 即自动色彩校正技术和自动曝光校正技术。自动色彩校正技术从图像中获取信息以确定真实的颜色特性，并改善不正确的彩色像素中的颜色。自动曝光校正技术测量所有像素的平均强度，并逐像素地调整整个图像以补偿曝光或曝光过度。这些技术是独立的，因为每个可以应用于不同于另一个的图像，或者它们都可以以任何所需的顺序应用。

摘要： A mobile device is provided that includes a digit input that can be manipulated by a user's fingers or thumb, an air conduction microphone and an alternative sensor that provides an alternative sensor signal indicative of speech. Under some embodiments, the mobile device also includes a proximity sensor that provides a proximity signal indicative of the distance from the mobile device to an object. Under some embodiments, the signal from the air conduction microphone, the alternative sensor signal, and the proximity signal are used to form an estimate of a clean speech value. In further embodiments, a sound is produced through a speaker in the mobile device based on the amount of noise in the clean speech value. In other embodiments, the sound produced through the speaker is based on the proximity sensor signal.

摘要： A system that captures both whiteboard content and audio signals of a meeting using a video camera and records or transmits them in real-time. The Real-Time Whiteboard Capture captures pen strokes on whiteboards in real time using an off-the-shelf video camera. Unlike many existing tools, the RTWCS does not instrument the pens or the whiteboard. It analyzes the sequence of captured video images in real time, classifies the pixels into whiteboard background, pen strokes and foreground objects (e.g., people in front of the whiteboard), and extracts newly written pen strokes. This allows the RTWCS to transmit whiteboard contents using very low bandwidth to remote meeting participants. Combined with other teleconferencing tools such as voice conference and application sharing, the RTWCS becomes a powerful tool to share ideas during online meetings.

摘要： A real-time approximately 360 degree image correction system and a method for alleviating distortion and perception problems in images captured by omni-directional cameras. In general, the real-time panoramic image correction method generates a warp table from pixel coordinates of a panoramic image and applies the warp table to the panoramic image to create a corrected panoramic image. The corrections are performed using a parametric class of warping functions that include Spatially Varying Uniform (SVU) scaling functions. The SVU scaling functions and scaling factors are used to perform vertical scaling and horizontal scaling on the panoramic image pixel coordinates. A horizontal distortion correction is performed using the SVU scaling functions at at least two different scaling factors. This processing generates a warp table that can be applied to the panoramic image to yield the corrected panoramic image. In one embodiment the warp table is concatenated with a stitching table used to create the panoramic image.

摘要： Described herein is a technique for creating a 3D face model using images obtained from an inexpensive camera associated with a general-purpose computer. Two still images of the user are captured, and two video sequences. The user is asked to identify five facial features, which are used to calculate a mask and to perform fitting operations. Based on a comparison of the still images, deformation vectors are applied to a neutral face model to create the 3D model. The video sequences are used to create a texture map. The process of creating the texture map references the previously obtained 3D model to determine poses of the sequential video images.
