A method and apparatus for extracting a model vector representation from multimedia documents. A model vector provides a multidimensional representation of the confidence with which multimedia documents belong to a set of categories or with which a set of semantic concepts relate to the documents. A model vector can be associated with multimedia documents to provide an index of its content or categorization and can be used for comparing, searching, classifying, or clustering multimedia documents. A model vector can be used for purposes of information discovery, personalizing multimedia content, and querying a multimedia information repository.

A finger sensing device includes a finger sensing area, and a processor cooperating therewith for reducing a number of possible match combinations between a sensed finger data set and each of a plurality of enrolled finger data sets. The processor may reduce the number of possible match combinations by generating a plurality of overlap hypotheses for each possible match combination, generating a co-occurrence matrix score based upon the plurality of overlap hypotheses for each possible match combination, and comparing the co-occurrence matrix scores to thereby reduce the number of possible match combinations. The processor may also perform a match operation for the sensed finger data set based upon the reduced number of possible match combinations. The sensed finger data set may include a sensed finger ridge flow data set, and each enrolled finger data set may include an enrolled finger ridge flow data set.

The present invention relates to the encoding and decoding of image information. According to the present invention, the decoding method comprises the steps of: entropy-decoding received information; performing inter prediction on a current block based on the entropy-decoded information; and restoring images by using the prediction results, wherein, in the inter prediction step, a skip mode or merge mode is applied to the current block and movement information of the current block may be determined based on the movement information of a neighboring block of the current block.

Systems, methods, and computer products that improve the techniques used to search multidimensional databases over techniques of the past. The preferred embodiment of the present invention advantageously improves the technique of determining a grid index that is used to locate a geometric shape in a spatial database. More particularly, the preferred embodiment of the present invention improves the technique of defining the grid cell size in a grid for a given data set, thereby improving the grid indexing process that locates a particular minimum-bounding rectangle and the associated geometric shape.

The present invention relates to an apparatus and methods for achieving phase-matching between various waves and/or modes by operation of a waveguide. Phase-matching between interacting waves is achieved by total internal reflection and transverse Bragg reflection waveguides. Using second harmonic generation in GaAs/AlGaAs as an example, properties are investigated and quantified such as nonlinear coupling efficiency, bandwidth, tunability, and limitations due to dispersion. The technique is advantageous when compared to alternate technologies, where it is particularly attractive as a material independent means to obtain ultra-low-loss nonlinear optical elements for monolithic integration with coherent light source and other active devices.

A system and method for assigning attributes to XML document nodes to facilitate their storage in relational databases and the subsequent retrieval and re-construction of pertinent nodes and fragments in original document order is provided. Since these queries are performed using relational database query engines, the speed of their execution is significantly faster than that using more exotic systems such as object-oriented databases. Furthermore, this method is portable across all vendor platforms, and so can be deployed at client sites without additional investments in database software.

Techniques for efficiently indexing and searching similar data are described herein. According to one embodiment, in response to a query for one or more terms received from a client, a query index is accessed to retrieve a list of one or more super files. Each super file is associated with a group of similar files. Each super file includes terms and/or sequences of terms obtained from the associated group of similar files. Thereafter, the super files representing groups of similar files are presented to the client, where each of the super files includes at least one of the queried terms. Other methods and apparatuses are also described.

The invention relates to a method and a system for identifying a form in a layout file and belongs to the technical field of mode identification in the field of computer information processing. The conventional mode identification technology cannot effectively identify and automatically extract the form of a layout. In the method and the system, firstly, independent characters of the layout are combined and organized into content blocks by utilizing automatic combination technology; and secondly, form identification and content combination are performed according to spatial positions, character information and typesetting information of the content blocks. Through the method and the system, the form can be rapidly identified at high efficiency, and the form content is accurately organized through the analysis of the position and the typesetting information of the content of the paper layout.

Sketch-based image search may include receiving a query curve as a sketch query input and identifying a first plurality of oriented points based on the query curve. The first plurality of oriented points may be used to locate at least one image having a curve that includes a second plurality of oriented points that match at least some of the first plurality of oriented points. Implementations also include indexing a plurality of images by identifying at least one curve in each image and generating an index comprising a plurality of oriented points as index entries. The index entries are associated with the plurality of images based on corresponding oriented points in the identified curves in the images.

An indirection system in a shingled storage device is described that uses an efficient algorithm to map LBAs to DBAs based on a predetermined rule or assumption and then handles as exceptions LBAs that are not mapped according to the rule. The assumed rule is that a fixed-length set of sequential host LBAs are located at the start of an I-track. Embodiments of the invention use two tables to provide the mapping of LBAs to DBAs. The mapping assumed by the rule is embodied in the LBA Block Address Table (LBAT) which gives the corresponding I-track address for each LBA Block. The LBA exceptions are recorded using an Exception Pointer Table (EPT), which gives the pointer to the corresponding variable length Exception List for each LBA Block. The indexing into the LBAT and the EPT is made efficient by deriving the index from the LBA by a simple arithmetic operation.
