    Abstract: A digital document skew detection and correction system that uses horizontal pixel projection analysis to detect the prominent writing line of Arabic text. The system removes both small and large components and divides the document into segments. The system uses the pixel projection results at varying angles to pinpoint the highest horizontal pixel concentration corresponding to the writing line of the Arabic text to determine the skew angle for each divided document segment. The skew angle variable is averaged between the documents segments before being reattached; a user notification application is activated if the differences between skewed angles exceed a threshold. The original document is rotated in the opposite direction of the estimated skew angle to correct the skew.

    Abstract: Architecture that enables optical character recognition (OCR) of text in video frames at the rate at which the frames are received. Additionally, conflation is performed on multiple text recognition results in the frame sequence. The architecture comprises an OCR text recognition engine and a tracker system; the tracker system establishes a common coordinate system in which OCR results from different frames may be compared and/or combined. From a set of sequential video frames, a keyframe is chosen from which the reference coordinate system is established. An estimated transformation from keyframe coordinates to subsequent video frames is computed using the tracker system. When text recognition is completed for any subsequent frame, the result coordinates can be related to the keyframe using the inverse transformation from the processed frame to the reference keyframe. The results can be rendered for viewing as the results are obtained.

A final digital relief form is generated and said final digital relief form and said digital image are projected in a geographical or cartographic system, for the purpose of their georeferencing. The pair of digital images in the same focal plane are acquired in a small stereoscopic base configuration by sensors located in the same focal plane.

  • Patent number: 8842902
    Abstract: In a method for aligning a part of a product (moving object) with a reference object, triangle data of the moving object is acquired, and feature elements of the moving object is fitted according to the triangle data. Feature elements of the reference object which match the feature elements of the moving object are determined, and the moving object is moved from a position of a center point of the feature elements of the moving object to a position of a center point of the matched feature elements of the reference object. A moving-and-rotating matrix of the moving object is obtained according to Quasi-Newton methods, and the moving object and the reference object are aligned by moving and rotating the moving object according to the moving-and-rotating matrix.

  • Patent number: 8831381
    Abstract: An electronic device and method use a camera to capture an image of an environment outside the electronic device followed by identification of regions, based on pixel intensities in the image. At least one processor automatically computes multiple values of an indicator of skew in multiple regions in the image respectively. The multiple values are specific to the multiple regions, and thereafter used to determine whether unacceptable skew is present across the regions, e.g. globally in the image as a whole. When skew is determined to be unacceptable, user input is requested to correct the skew, e.g. by displaying on a screen, a symbol and receiving user input (e.g. by rotating an area of touch or rotating the electronic device) to align a direction of the symbol with a direction of the image, and then the process may repeat (e.g. capture image, detect skew, and if necessary request user input).

  • Patent number: 8818132
    Abstract: A “Camera Calibrator” provides various techniques for recovering intrinsic camera parameters and distortion characteristics by processing a set of one or more input images. These techniques are based on extracting “Transform Invariant Low-Rank Textures” (TILT) from input images using high-dimensional convex optimization tools for matrix rank minimization and sparse signal recovery. The Camera Calibrator provides a simple, accurate, and flexible method to calibrate intrinsic parameters of a camera even with significant lens distortion, noise, errors, partial occlusions, illumination and viewpoint change, etc. Distortions caused by the camera can then be automatically corrected or removed from images. Calibration is achieved under a wide range of practical scenarios, including using multiple images of a known pattern, multiple images of an unknown pattern, single or multiple images of multiple patterns, etc.

    Abstract: A biometric authentication apparatus includes an image shooting unit to capture a vessel image of a person to be authenticated and an authentication unit to verify verification vessel position information of the captured vessel image of the person to be authenticated against registered vessel position information of a registered vessel image registered in advance. When the verification vessel position information is not identical with the registered vessel position information, the authentication unit performs authentication using vessel size information of the registered vessel image registered in advance.

    Abstract: A portion within an image in which a plurality of objects (21 and 22) overlap is partitioned into a plurality of small regions (31a and 32a), each of the units of identification information for the plurality of objects (21 and 22) is assigned to a dot corresponding to the plurality of small regions (31a and 32a), and thereby, identification-use layout information is generated, whereby even if a plurality of objects overlap upon a layout of a display image, upon the layout of the identification-use layout information that has been generated for identifying the plurality of objects, the identification information corresponding to each object does not overlap. As a result, it is possible to identify each object by the identification information acquired from the position of the cursor.

  • Patent number: 8773739
    Abstract: An image reading device includes a conveying unit, reading unit, detecting unit, and control unit. The conveying unit conveys two sheets of the original one by one. The reading unit reads a sheet passing past a reading position. The detecting unit detects a sheet passing past a detection position upstream of the reading position in a conveying direction. The control unit controls the reading unit to start a reading process when a leading edge of sheet reaching a position upstream of the reading position by a first distance, controls the reading unit to stop the reading process when a trailing edge of sheet reaching a position downstream of the reading position by a second distance, determines an interspace between the trailing edge of sheet and a leading edge of a subsequently-conveyed sheet, and updates the first distance and the second distance based on the interspace.

  • Patent number: 8768101
    Abstract: A new optical imaging process for how to best fuse information from multiple target images into a single target image is described. The process has two primary components. First, rotating, translating and scaling each target image to register or calibrate them against a reference image and, second, determining weighing factors for each thus registered target image to select those images which add value to a final target image. The first component determines optimal rotational and translation matrices by a least squares measure using singular value decomposition. The second component determines weighing factors using correlations and statistical signal analysis techniques.
