摘要： A method of improving the lighting conditions of a real scene or video sequence. Digitally generated light is added to a scene for video conferencing over telecommunication networks. A virtual illumination equation takes into account light attenuation, lambertian and specular reflection. An image of an object is captured, a virtual light source illuminates the object within the image. In addition, the object can be the head of the user. The position of the head of the user is dynamically tracked so that an three-dimensional model is generated which is representative of the head of the user. Synthetic light is applied to a position on the model to form an illuminated model.

摘要： Systems and methods for encoding/decoding a video stream. Animated talking heads are coded using partial offline encoding, multiple video streams, and multiple reference frames. The content of a face animation video that is known beforehand is encoded offline and the remaining content is encoded online and included in the video stream. To reduce bit rate, a server can stream multiple video sequences to the client and the video sequences are stored in the client's frame store. The server sends instructions to play a particular video sequence instead of streaming the particular video sequence. Multiple video streams can also be streamed to the client. Positional data and blending data are also sent to properly position one video stream relative to another video stream and to blend one video stream into another video stream.

摘要： A system and method of providing sender-customization of multi-media messages through the use of emoticons is disclosed. The sender inserts the emoticons into a text message. As an animated face audibly delivers the text, emoticons associated with the message are started a predetermined period of time or number of words prior to the position of the emoticon in the message text and completed a predetermined length of time or number of words following the location of the emoticon. The sender may insert emoticons through the use of emoticon buttons that are icons available for choosing. Upon sender selections of an emoticon, an icon representing the emoticon is inserted into the text at the position of the cursor. Once an emoticon is chosen, the sender may also choose the amplitude for the emoticon and increased or decreased amplitude will be displayed in the icon inserted into the message text.
