Abstract: A method for pre-recognition processing of forms with non-fixed fields. One or more objects that are present on a form can be reliably identified after conversion of the form into an electronic state. Objects are preliminarily assigned to act as reference points for spatial binding of data input fields or groups thereof. In the case of a text object as a reference point, text recognition is additionally performed. The spatial location of a reference point may be not fixed. A reference point may be described as alternative. Field identification may be performed either automatically or manually.

Abstract: The proposed technical solution allows processing of machine-readable forms of unfixed format. It comprises a method of specifying the logical structure of a document characterized by: preliminary specification of the list and descriptions of varieties of elements which may be present in the form, specifying an algorithm of setting the search constraints for every element, description of at least the following characteristics of search for every simple or compound element—the spatial characteristics of the search area and the parametric characteristics of the element, description of the method of identification of obtained elements, testing the type of the element, testing the properties which are typical of the type, testing the completeness of composition of the parts of the element.

Abstract: Embodiments of the present invention disclose a method and system for restoring a motion-blurred image. The method comprises determining parameters for a one-dimensional Optical Transfer Function (OTF) for the motion-blurred image in Fourier space; determining a signal-to-noise ratio for the motion-blurred image in the Fourier space; and correcting for motion blur based on the parameters of the OTF. Determining the parameters comprises calculating a function ?(p,q) which is based on the square of the modulus of the Fourier transform |G(p,q)|2 of the motion-blurred image. The parameters include the absolute value of the one-dimensional OTF, and the phase and sign of the OTF.

Abstract: In one embodiment, the invention provides a method for binarizing an image. The method comprises establishing boundaries of image objects of the image and classifying each image object as either suspect or non-suspect. The method further comprises creating a local binarization threshold map comprising threshold binarization values associated with image objects classified as non-suspect and then expanding the local binarization threshold map to cover the entire image thereby to create a global binarization threshold map for the entire image.

Abstract: A device for obtaining graphical information from a single- or multi-page document printed on a hard media where reading out of the position of the document elements is performed by using a method of volumetric scanning of a document (even closed) is described. Processing of scanning results, comprises joining up the separate scanning layers scanning results, removing noise, correction of document image orientation, dividing information into portions relating to separate pages, is performed after reading the information. Then text information recognition contained in the graphical file is performed. Information may be read out by using methods of magnetic resonance scanning, supersonic scanning, X-ray scanning etc. The results of scanning in electronic form may be stored for further transmission thereof on a medium or via communication channels to a distant location for recognition.

Abstract: In one embodiment, a method for identifying areas in a document image is provided. The method comprises generating binarized and gradient images based on the document image; and performing a classification operation to classify areas in the document image into one of a noise area and a picture area based on attributes computed on the binarized and gradient images.

Abstract: The present invention deals with text comprising image parsed to graphemes. A result of character recognition is creation of one or more versions of characters for each grapheme. All possible words versions are obtained using all characters versions, and all parsing versions are examined. A supplementary data of several types is applied successively in the preliminarily prescribed order to the examined words. The processing with the use of supplemental data may be represented as a three times repeated processing of the same text fragment with the use of supplementary information becoming available at each time. The examination comprises three steps. 1) A set of chains LPG is built using all obtained recognized grapheme-to-character versions. 2) All obtained versions are analyzed with the successive application of subsequent supplemental data types in connection with the preliminarily assigned order or with a joint application thereof. 3) A supplementary space recognition correction.

Abstract: In one embodiment, a method for correcting distortions in a scanned image of a page is disclosed. The method comprises identifying at least one set of collinear elements in the scanned image; and generating a corrected image based on the scanned image including for at least some of the collinear elements in each set applying a spatial location correction to position all collinear elements in the set on a common horizontal rectilinear base line in the corrected image.

Abstract: An adjustment method of a machine-readable form model and a filled form scanned image thereof in the presence of distortion comprising model form free of distortion, image form, containing distortion, obtained by optical input device from paper media. One embodiment of the method comprises the steps of assigning of one of the forms as changeable, marking on the form regions containing distortion, computing the consolidated distortion correction factor of the spatial parameters for the said changeable form, parameters correction on the base of the said consolidated factor. Another embodiment of the method setting the correspondence between identical objects of image form and model form is followed by steps of computing distortion correction factors of the spatial parameters for each object of selected level, spatial parameters correction of the changeable form, on the base of the said factors, affecting objects of the same and lower identification reliability levels.

Abstract: A method is described of bit-mapped image analysis comprising division of all analysis means at one's disposal into several groups differing in accuracy and further processing multi-stage analysis. The analysis comprises a primary analysis stage and at least one profound analysis stage, with supplemental data collected at both stages. The primary analysis, includes preliminary recognition of objects with distortion and detection of objects that require more precise analysis means to overcome the distortion. At the primary analysis stage, the analysis means from the group of the most inaccurate group are used. The profound analysis stage includes repeating recognition of objects with a distortion taking into account the supplemental data obtained at the previous stage, detecting objects that require more precise analysis means to overcome the distortion, and collection of newly appeared supplemental data. Each subsequent profound analysis stage uses analysis means from the group of more accurate means.
