Filed:

Dec 16, 2004

Appl. No.:

11/013865

Inventors:

James E. Crenshaw - Palatine IL, US

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G06K 9/00

US Classification:

382100, 382118, 382181

Abstract:

Upon determining () a need for image recognition facilitation content, a corresponding process () first determines ( and ) whether adequate local resources are available. When true, those local resources are used () to facilitate the desired image recognition. When false, however, one or more remote resources are accessed () and supplemental image recognition facilitation content is received () and locally used () to effect the desired image recognition process. Local memory management can optionally comprise, if desired, deletion () of some (or all) locally stored image recognition facilitation content and/or storage () of the remotely sourced image recognition facilitation content.

US Classification:

382106, 382100, 356 3, 34820815, 34833304

Abstract:

A system and method for reducing distance-based distortion in a camera image of an object, where the distanced-based distortion is due to differences in distance from the camera to different parts of the object. In one approach, the distortion is reduced by estimating distances to different parts of the object and then generating a reprojected image of the object dependent upon the estimated distances and upon a virtual viewpoint that is more distant than the camera from the object. In a further approach, the image is warped such that points in the image match corresponding points in one or more stored templates. In a still further approach, if excessive distortion is present in the image, the camera zoom is increased and a magnified image is displayed, prompting a person to move farther from the camera thereby reducing the distortion.

Inventors:

James E. Crenshaw - Palatine IL, US

Assignee:

Motorola Mobility, Inc. - Libertyville IL

International Classification:

G06K 9/20

US Classification:

382293, 382276

Abstract:

Straight lines in a compensated image of a wide-angle image are identified () and corresponding curved lines of pixels in the wide-angle image identified () as well. For given points in the aforementioned straight lines, a corresponding point in the corresponding curved lines is identified by determining an intersection of those curved lines with another line of pixels in the wide-angle image (). The latter can comprise either a curved line that corresponds to another straight line in the compensated image, in which case the intersection is noted by tracing the curved lines using a scan-rasterization algorithm. The latter can also comprise, if desired, a straight line that corresponds to another straight line in the compensated image. In either case, the point of intersection is readily and efficiently determined.

US Classification:

382115, 382286, 340 582, 348E13004

Abstract:

A method is provided for identifying and verifying a person using hand biometrics with an anti-spoofing measure. The method comprises acquiring () a first image () of a hand in a first configuration, acquiring () a second image () of the hand in one of the first and a second configuration for comparison with the first image (), determining () whether a person can be identified from at least one of the first image () and the second image (), and determining () from a comparison of the second image () with the first image () whether the hand is a counterfeit.

International Classification:

H04N 7/14

US Classification:

348 1404, 348 1401

Abstract:

A videotelephony system has an electronically controllable camera with a field of view, a visual token disposed within the field of view, and a camera controller. The camera controller is configured to detect the visual token and reconfigure the field of view relative to a detected position of the visual token.

Assignee:

General Instrument Corporation - Horsham PA

International Classification:

H04N 60/33

US Classification:

725 10, 725 12

Abstract:

A system and method of measuring audience reaction to media content includes obtaining images or other information of each individual of the audience as the individual views the content and analyzing the images or other information with software to generate emotional response source data for each individual. The emotional response source data identifies the emotion or emotions or change of emotions of the individual as interpreted by the software. The emotional response source data of the individuals is aggregated to identify a set of primary emotions of the audience, and thereafter, the emotional response source data is re-evaluated in view of the primary emotions to refine and more accurately classify the emotional responses of each individual of the audience.

US Classification:

375/240160, 348/699000

Abstract:

A method according to the invention includes the steps of determining a signature metric () for a portion of a first image (). A second image () is searched () for at least one relative match of the signature metric, yielding one or more candidate regions. In a pixel domain, the one or more candidate regions are searched () for the portion of the first image to obtain a motion vector for the first image (). The second image () is searched in a search window () that is smaller than the area of the second image ().
