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.

Perspective improvement for image and video applications

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.

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.

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.

Method and apparatus to facilitate forming a compensated image of a wide-angle image

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.

Image recognition facilitation using remotely sourced content

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.
