09/222566

Inventors:

Ning Lu - Mountain View CA

Assignee:

Sony Corporation - Tokyo
Sony Electronics, Inc. - Park Ridge NJ

International Classification:

G06K 962

US Classification:

382209, 707 6

Abstract:

A method and an apparatus for content identification and categorization of textual data is disclosed. Using the Burrows-Wheeler transform in conjunction with mapping techniques and statistical comparison, useful information can be extracted from textual documents. This information can be used to categorize, authenticate, and compare such documents, thereby leading to automated searching of databases of documents.

International Classification:

G06F 1727

US Classification:

704 9, 707 7, 704 10

Abstract:

A method and an apparatus for sorting is disclosed. This method of sorting is adapted to sorting textual data in an efficient manner, but could be applied to other types of data with similarly satisfactory results. The method breaks marked data items to be sorted down into groups, each group sorted relative to other groups, and then sorts those subgroups as necessary, thereby minimizing comparisons and swapping.

US Classification:

348416, 37524016

Abstract:

An innovative method and apparatus for decoding an encoded image such as a video. In one embodiment a method for decoding an encoded block of an image, e. g. ,a video frame, having an error in its motion vector is disclosed. Sub-blocks are extracted from neighboring blocks to the encoded block. A motion vector is generated for each sub-portion and the generated motion vectors are used, for example, averaged, to estimate a motion vector for the encoded portion.

US Classification:

342 13, 342 42, 342190, 342191, 702 5, 702127

Abstract:

Systems and methods for monitoring and classifying RF emissions in the field include storing an electronic signature map (ESM) of a selected geographic area, where the electronic signature map includes previously detected emitter closeness measures (ECMs) in the selected geographic area. The ECMs are representative of detected sources of radio frequency energy. A RF energy emission is detected, a new ECM for that RF energy emission is created, and that the new ECM is compared with the ECMs in the ESM. That comparison may help to determine whether the RF energy emission should be considered a threat.

International Classification:

H04K 3/00

US Classification:

455 1, 4554561, 455513, 4551153, 4554042, 455456, 342 14, 342 16, 342 17

Abstract:

According to an embodiment of the present invention jamming energy is allocated to a plurality of emitters based on a three-dimensional (3-D) emitter geolocation technique that determines the geolocation of radio frequency (RF) emitters based on energy or received signal strength (RSS) and/or time differences of arrival (TDOAs) of transmitted signals. The three-dimensional (3-D) emitter geolocations are used to rank emitters of interest according to distance and available radio frequency (RF) jamming energy is allocated to the emitters in rank order. The techniques may be employed with small unmanned air vehicles (UAV), and obtains efficient use of jamming energy when applied to radio frequency (RF) emitters of interest.

Inventors:

Ning Lu - Mountain View CA, US

International Classification:

H04N011/04

US Classification:

375240100

Abstract:

An image encoding system includes a processor and a memory device coupled to the processor. The processor is configured to receive input data containing image information, to generate encoded data based on a frequency domain transform of the input data, and to selectively generate an encoded reference based on a frequency domain transform of the input data. The system also includes a memory device coupled to the processor. The processor is further configured to store the generated encoded reference in the memory device when no encoded reference is available in the memory device and generate residue data representing the difference between the encoded data and the stored encoded reference when the encoded reference is available in the memory device.
