    摘要： In one embodiment, a fingerprint is generated for each document (e.g., e-mail, web page) containing markup language (e.g., HTML) code. The fingerprint is indicative of the structure of the markup language code in the document. The fingerprint may be formed by extracting markup language tags from the document and then linking together the extracted tags to form a single string. The fingerprint may be hashed through a hashing function to generate a signature key that may be used to create a directory for the document and other documents having the same fingerprint. The grouping of documents with the same fingerprint facilitates creation of anti-spam rules or identification of web pages from particular websites, for example.

    摘要翻译： 在一个实施例中，为包含标记语言（例如，HTML）代码的每个文档（例如，电子邮件，网页）生成指纹。 该指纹指示文档中标记语言代码的结构。 可以通过从文档提取标记语言标签然后将提取的标签链接在一起以形成单个字符串来形成指纹。 可以通过散列函数对指纹进行散列，以生成签名密钥，该签名密钥可用于为文档和具有相同指纹的其他文档创建目录。 具有相同指纹的文档分组有助于创建反垃圾邮件规则或从特定网站识别网页。

    摘要： A method of tracking an inventory of objects via a mobile communications device includes acquiring an image of one or more of the objects via the mobile communications device, which also collects a location of the mobile communications device while acquiring the image of the one or more of the objects. The location and image are transferred from the mobile communications device to a remote server via a wireless network, such that the one or more of the objects are identified at the server based on the image, and the location and identity of the one or more objects are stored on a database associated with the server.

    摘要： The described system and method provide joint rate control and scalable stream adaptation for multiple clients concurrently competing for the same access networks. For each such client, an optimization problem is constructed and solved to determine the streaming rate over each access network, the video packets to be transmitted, and the access network over which each video packet is sent. The rate control and stream adaptation problem is constructed as an integer program in an embodiment of the invention, with an objective to minimize a cost function of the expected video distortion. Randomized packet scheduling is accounted for in an embodiment of the invention by relaxing the integer program into real-valued optimization programs and deriving convex programming approximations.

    摘要： A method for encoding video for streaming includes receiving a plurality of sequential image frames generated by a 3D graphics rendering engine. Graphics rendering contexts are obtained, including pixel depth map, rendering camera parameters, and camera motion from the 3D rendering engine. The method next entails selecting key frames among the plurality of sequential image frames, interpolating non-key frames via 3D image warping, and encoding all key frames and warping residues of non-key frames. The system is implementable on a server linked to a mobile user device for receiving the encoded frame data. The mobile user device is configured to decode the encoded frame data and display a corresponding image to a user of the mobile user device.
