20080232706 | METHOD AND APPARATUS FOR ENCODING AND DECODING IMAGE USING PIXEL-BASED CONTEXT MODEL - A method and apparatus for encoding and decoding an image are provided. The method includes selecting a context model by referring to previously encoded pixels that are adjacent to the current pixel for entropy-encoding a binary value of a pixel value of the current pixel, and entropy-encoding the binary value using the selected context model, thereby performing entropy-coding with high compression efficiency. | 09-25-2008 |
20080240247 | METHOD OF ENCODING AND DECODING MOTION MODEL PARAMETERS AND VIDEO ENCODING AND DECODING METHOD AND APPARATUS USING MOTION MODEL PARAMETERS - Provided are a method of efficiently transmitting motion model parameters using temporal correlation between video frames and a video encoding and decoding method and apparatus, in which motion estimation and motion compensation are performed by generating a plurality of reference pictures that are motion-compensated using motion model parameters. Motion model parameters are encoded based on temporal correlation between motion vectors of representative points expressing the motion model parameters, global motion compensation is performed on a previous reference video frame using motion model parameters in order to generate a plurality of transformation reference pictures, and a current video frame is encoded using the plurality of transformation reference pictures. | 10-02-2008 |
20080240592 | IMAGE ENCODING AND DECODING METHOD AND APPARATUS USING MOTION COMPENSATION FILTERING - Provided are an image encoding method and apparatus for encoding image data, in which compression efficiency is further improved by filtering motion-compensated image data, thereby reducing errors with respect to original image data, and an image decoding method and apparatus for decoding encoded image data. A filter is generated using previously decoded surrounding pixels of a current frame and surrounding pixels of a reference frame, and prediction data is then filtered using the generated filter. Therefore, it is possible to decrease a size of residual data to be encoded. | 10-02-2008 |

20080294652 | Personalized Identification Of System Resources - A processing device may display a representation of a system resource. The system resource may include a menu, a folder, a filename, a shortcut, a textbox, or other resource. The user may make a gesture to indicate a desire to create a personalized identifier for the system resource. The processing device may display a personalized identifier writing area for inputting personalized identifier information. Personalized identifier information may be input via text, speech, digital ink, or other methods. The processing device may permit the user to configure types of information to be stored with personalized identifiers and how the personalized identifier information may be indexed for searching. In one embodiment, the input personalized identifier information may be translated to a second language and indexed for searching. Further, the processing device may permit the user to configure whether or how to display a personalized identifier for a system resource. | 11-27-2008 |
20080310723 | TEXT PREDICTION WITH PARTIAL SELECTION IN A VARIETY OF DOMAINS - A computing system may predict a word based on received user input that selects a part of the word (e.g., the first characters, the first root, etc.). Specifically, a program, when run on the computing system, may perform a method including creating a candidate list of words based on received user input. These words may be then organized into a hierarchy, or tree structure, in which each word is associated with a parent and each parent is a partial match for its associated words. The top-tier partial matches may be presented, and user input corresponding to a selected partial match may be received. A set of candidates related to the selected partial match may then be presented for user selection. | 12-18-2008 |
20090006261 | PORTABLE DEVICE FOR CARRYING LICENSES - A licensing device is used for storing one or more licenses for licensable content such as music, video, e-books, software applications, online memberships, and the like. The licensing device communicates with a user's computing devices enabling licensable content to be downloaded and/or activated on a particular computing device. The communication can take many forms such as wireless, wired, or optical. Downloading and/or activation of the content upon confirmation of a valid license may be automatic or partially based on user input. | 01-01-2009 |
20110225133 | METADATA-AWARE SEARCH ENGINE - Described herein are various principles that may be used together or separately to implement a search engine to retrieve and use metadata information in performing a search. In one embodiment described herein, a search engine accepts input from a user that describes a search the user desires to be performed. The search engine may then examine the input to determine whether the input relates to an artifact and to what artifact the input relates. The search engine may then retrieve metadata information from a source related to the determined artifact and use the metadata information in performing the search requested by the user. | 09-15-2011 |
20110225644 | BEHAVIOR-BASED SECURITY SYSTEM - Described herein are techniques for operating a security server to determine behavioral profiles for entities in a network and to detect attacks or unauthorized traffic in a network based on those behavioral profiles. In one technique, a behavioral profile may be generated based on requests for security operations to be performed that are received at a security server from an entity in a network. The behavioral profile may be generated using learning techniques, including artificial intelligence techniques such as neural networks. When the security server receives from an entity one or more requests for security operations to be performed, the security server may compare properties of the requests to the behavioral profile for the entity and properties of requests commonly sent by the entity. The security server may determine a similarity score indicating how similar the request are to the behavioral profile and to requests commonly received from the entity. | 09-15-2011 |
20130218918 | CLAIM BASED EXECUTION CONTROL - Methods, systems, and computer program products are provided for using a claims model to control the execution of an execution unit. The execution unit is executed. An identity principal is identified under which the execution unit is executed. At least one claim is identified that is required for the execution unit. Each identified claim has a claim name and a claim value. One or more claims associated with the identified identity principal is/are requested from a claims provider. The claim(s) is/are received from the claims provider. The received claim(s) is/are compared with the identified claim(s). An action for the identified claim(s) is determined based on a result of the comparison. | 08-22-2013 |
