US Classification:

382307, 712 10, 712 16, 382281

Abstract:

An array transform system for parallel computation of a plurality of elements of an array transform includes a memory for storing an array of data elements. Each column of data elements from the memory is copied to a shifter that shifts the column of data elements in accordance with a shift value to produce a shifted column of data elements. The shifted columns of data elements are accumulated in a plurality of accumulators, with each accumulator producing an element of the array transform. A controller controls the shift value dependent upon the position of the column of data elements in the array of data elements.

Abstract:

An interface () to a video imaging device () that generates captured frames of a video image () is described. The interface includes control registers () that store at least two sets of stream parameters () corresponding to at least two regions of interest (ROIs) and a function () that generates at least two corresponding ROI video streams () that are derived from the captured frames as essentially simultaneous output signals using the at least two sets of stream parameters. In some embodiments a new selection value () is determined from a current selection value and a derivative parameter stored as a portion of a set of stream parameters. In these embodiments, the generating of the at least two corresponding ROI video streams as essentially simultaneous output signals includes using the new selection value.

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.

US Classification:

716018000

Abstract:

A streaming processor circuit of a processing system is automatically generated by selecting a set of circuit parameters consistent with a set of circuit constraints and generating a representation of a candidate streaming processor circuit based upon the set of circuit parameters to execute one or more iterations of a computation specified by a streaming data flow graph. The candidate streaming processor circuit is evaluated with respect to one or more quality metrics and the representation of the candidate streaming processor circuit is output if the candidate streaming processor circuit satisfies a set of processing system constraints and is better in at least one of the one or more quality metrics than other candidate streaming processor circuits.

International Classification:

G06K 9/00

US Classification:

382105

Abstract:

A system includes an interface that receives an image, which includes a motor vehicle and background, and a processing device that performs a method for object recognition on the received image. The method includes the steps of: determining motion information corresponding to at least one of the moving vehicle and the background; detecting the moving vehicle in the image using the motion information; detecting an object of interest on the moving vehicle; and performing an object recognition process on the object of interest. The system may be part of a license plate recognition system.

US Classification:

348157, 348E07085

Abstract:

A device for use with an imaging system that is operable to provide an image signal based on an object disposed at a first distance from the imaging system. The imaging system includes a first camera, a second camera and a display. The first camera is operable to generate a first image signal based on the object and includes a first optics system and a first detector. The first optics system has a focal length, whereas the first detector has a resolution. The second camera is operable to generate a second image signal based on the object. The second camera includes a second optics system and a second detector. The second optics system has the same focal length of the first optics system and the second detector has the same resolution as the first detector. The second camera is separated from the first camera by a second distance. The display is operable to display an image based on a modified image. The device comprises an image processor that is operable to establish a virtual separation membrane and to output a modified image based on the first image signal, the second image signal, the virtual separation membrane, the second distance, the focal length and the resolution.
