摘要： A method of digitally adding the appearance of makeup to a videoconferencing participant. The system and method for applying digital make-up operates in a loop processing sequential video frames. For each input frame, there are typically three general steps: 1) Locating the face and eye and mouth regions; 2) Applying digital make-up to the face, preferably with the exception of the eye and open mouth areas; and 3) Blending the make-up region with the rest of the face. In one embodiment of the invention, the background in the frame containing a video conferencing participant can also be modified so that other video conferencing participants cannot clearly see the background behind the participant in the image frame. In one such embodiment of the invention, the video conferencing participant tries to make his or her own image look comical or altered. In another embodiment of the invention, a particular remote participant tries to make another participant look funny to the other participants.

摘要： Systems and methods are disclosed that facilitate real-time information exchange in a multimedia conferencing environment. Data Client(s) facilitate data collaboration between users and are maintained separately from audio/video (AV) Clients that provide real-time communication functionality. Data Clients can be remotely located with respect to one another and with respect to a server. A remote user Stand-in Device can be provided that comprises a display to present a remote user to local users, a digital automatic pan/tilt/zoom camera to capture imagery in, for example, a conference room and provide real-time information to an AV Client in a remote office, and a microphone array that can similarly provide real-time audio information from the conference room to an AV Client in the remote office. The invention further facilitates file transfer and presentation broadcast between Data Clients in a single location or in a plurality of disparate locations.

摘要： Background blurring is an effective way to both preserve privacy and keep communication effective during video conferencing. The present image background blurring technique is a light weight real-time technique to perform background blurring using a fast background modeling procedure combined with an object (e.g., face) detector/tracker. A soft decision is made at each pixel whether it belongs to the foreground or the background based on multiple vision features. The classification results are mapped to a per-pixel blurring radius image to blur the background. In another embodiment, the image background blurring technique blurs the background of the image without using the object detector.
摘要翻译：背景模糊是在视频会议中保持隐私和保持通信有效的有效方式。目前的图像背景模糊技术是使用与对象（例如脸部）检测器/跟踪器组合的快速背景建模过程来执行背景模糊的轻量级实时技术。基于多个视觉特征，在每个像素上做出软判决是否属于前景或背景。分类结果映射到每像素模糊半径图像以模糊背景。在另一个实施例中，图像背景模糊技术在不使用对象检测器的情况下模糊图像的背景。

摘要： A program distribution system includes a plurality of set-top boxes that receive broadcast programming and segmentation data from content and information providers. The segmentation information indicates portions of programs that are to be included in skimmed or condensed versions of the received programming, and is produced using manual or automated methods. Automated methods include the use of ancillary production data to detect the most important parts of a program. A user interface allows a user to control time scale modification and skimming during playback, and also allows the user to easily browse to different points within the current program.

摘要： A “virtual video studio”, as described herein, provides a highly portable real-time capability to automatically capture, record, and edit a plurality of video streams of a presentation, such as, for example, a speech, lecture, seminar, classroom instruction, talk-show, teleconference, etc., along with any accompanying exhibits, such as a corresponding slide presentation, using a suite of one or more unmanned cameras controlled by a set of videography rules. The resulting video output may then either be stored for later use, or broadcast in real-time to a remote audience. This real-time capability is achieved by using an abstraction of “virtual cameramen” and physical cameras in combination with a scriptable interface to the aforementioned videography rules for capturing and editing the recorded video to create a composite video of the presentation in real-time under the control of a “virtual director.”

摘要： A combined digital and mechanical tracking system and process for generating a video using a single digital video camera that tracks a person or object of interest moving in a scene is presented. This generally involves operating the camera at a higher resolution than is needed for the application, and cropping a sub-region out of the image captured that is output as the output video. The person or object being tracked is at least partially contained within the cropped sub-region. As the person or object moves within the field of view of the camera, the location of the cropped sub-region is also moved so as to keep the subject of interest within its boundaries. When the subject of interest moves to the boundary of the FOV of the camera, the camera is mechanically panned to keep the person or object inside its FOV.
