Feb 6, 1998

Appl. No.:

09/020044

Inventors:

Andrew Dean Christian - Lincoln MA
Brian Lyndall Avery - Lexington MA

Assignee:

Compaq Computer Corporation - Houston TX

International Classification:

G06K 900

US Classification:

382103, 382107, 382199, 348 29, 348 39, 348155, 348169

Abstract:

A technique for tracking objects through a series of images is disclosed. In one embodiment, the technique is realized by obtaining at least first and second representations of a plurality of pixels, wherein at least one grouping of substantially adjacent pixels has been identified in each of the first and second representations. Each identified grouping of substantially adjacent pixels in the first representation is then matched with an identified grouping of substantially adjacent pixels in the second representation.

International Classification:

G06K 968

US Classification:

382219, 382162, 358520, 345 22, 348631

Abstract:

A technique for differencing an image is disclosed. In one embodiment, the technique is realized by measuring light values in a scene to generate a first image and a second image. The first image is separated into first luminance and chrominance components, and the second image is separated into second luminance and chrominance components. A difference is determined between the first and the second luminance components to generate a luminance mask. Similarly, a difference is determined between the first and the second chrominence components to generate a chrominance mask. The luminance mask and the chrominence mask are combined to determine a difference between the first and the second images.

Abstract:

A technique for locating objects within an image is disclosed. In one embodiment, the technique is realized by obtaining an image and then identifying an object within the image based upon an orientation of the object within the image. The image can be a representation of a plurality of pixels, wherein the plurality of pixels are arranged in a plurality of columns and rows, and wherein at least some of the plurality of pixels are enabled to represent the object.

International Classification:

G06K 900

US Classification:

382165, 382103, 382283, 348152

Abstract:

A technique for classifying objects within an image is disclosed. In one embodiment, the technique is realized by identifying a portion of an image, and then filtering the portion of the image based upon an object characteristic and a reference within the image. The image can be a representation of a plurality of pixels, wherein at least some of the plurality of pixels are enabled to represent the identified portion of the image. The reference can be one of a reference plane or a terrain within the image.

Brian Avery - Lexington MA, US
Steven Ayer - Marblehead MA, US

International Classification:

G06F015/173

US Classification:

709223000, 709224000

Abstract:

Several sensors or other data collecting and transmitting devices may be made accessible to computers on a network by advertising their presence and establishing communications. This may be accomplished by using a standard network protocol and an aggregating device on the network. One such protocol is the Session Initiation Protocol. The sensor devices may be heterogeneous.

International Classification:

H04L 12/66

US Classification:

370352000

Abstract:

A voice data security method and apparatus of the present invention modifies a subject voice data stream. Modification is by insertion of noise or similar interference effects. The amount of audio distortion is controllable. Audio or voice communications over a data network are thus made secure, and unauthorized use of the data network over voice channels is prevented.

Appl. No.:

12/004543

Inventors:

Andrew Christian - Lincoln MA, US
Brian Avery - Lexington MA, US

International Classification:

H04Q 7/20

US Classification:

4554261, 4554141

Abstract:

An apparatus includes a data processor; a user interface; a first communication interface through which a call may made; a second communication interface; and a memory that stores information received through the second communication interface. The information is received from at least one mobile communication device when disposed in proximity to the apparatus, such as being received through a Bluetooth link. The data processor is configurable to operate with the user interface, the memory and the first communication interface to initiate a call to the at least one mobile communication device using the stored information. The call is initiated when the at least one mobile communication device is no longer disposed in proximity to the apparatus. In the exemplary embodiments the stored identification-related information enables a user of the apparatus to continue a face-to-face conversation conducted with a user of the at least one second mobile device after the user of the second mobile device is no longer in proximity to the user of the apparatus.
