20150331852 | FINDING AN APPROPRIATE MEANING OF AN ENTRY IN A TEXT - Disclosed are systems, computer-readable mediums, and methods for providing a meaning of an entry in a text is described. A lexico-morphological analysis is performed on the text. A syntactical analysis is performed on the text. A semantic analysis is performed on the text. A syntactical structure and a semantic structure for the entry is chosen. One or more syntactic links between each alternative meaning of words in proximity to the entry is determined. A weight is determined. One or more semantic links between each word in proximity to the entry are determined. For each semantic link, a weight associated with each semantic link is determined; and based on the weights associated with each semantic and syntactic link, determining meaning of the entry. | 11-19-2015 |
20150085327 | METHOD AND APPARATUS FOR USING AN ENLARGEMENT OPERATION TO REDUCE VISUALLY DETECTED DEFECTS IN AN IMAGE - Systems and method for improving the quality of document images are provided. One method includes identifying a plurality of image fragments within a previously received document image that includes text. The method further includes separating the plurality of image fragments into a plurality of classes. Each class includes a subset of the plurality of image fragments that are substantially similar to one another. The method further includes, for each of the plurality of classes: (1) processing a class of image fragments to generate a combined and substantially enlarged image fragment for the class; and (2) filtering the combined and substantially enlarged image fragment to generate a filtered image fragment for the class. The method further includes generating an improved document image by replacing or modifying the image fragments within the document image based on the filtered image fragments. | 03-26-2015 |

20140376060 | AUTOMATIC CAPTURING OF DOCUMENTS HAVING PRELIMINARILY SPECIFIED GEOMETRIC PROPORTIONS - Methods, devices, and systems for capturing documents are provided. A frame in a viewfinder is selected and is converted into a binary version. Segmentation of the binarized version of the frame is performed using computed horizontal and vertical histograms. At least one document is identified in the selected frame. The at least one document is captured upon determining that values of the one or more parameters associated with the document match predetermined values of corresponding one or more parameters. | 12-25-2014 |
20140307967 | STRAIGHTENING OUT DISTORTED PERSPECTIVE ON IMAGES - Methods for correcting distortions in an image including text, or an image of a page that includes text, are disclosed. The methods include identifying reliable and substantially straight lines from elements in the image. Vanishing points are determined from the lines. Parameters associated with a rectangle are determined. A coordinate conversion is performed. | 10-16-2014 |
20140307959 | METHOD AND SYSTEM OF PRE-ANALYSIS AND AUTOMATED CLASSIFICATION OF DOCUMENTS - Automatic classification of different types of documents is disclosed. An image of a form or document is captured. The document is assigned to one or more type definitions by identifying one or more objects within the image of the document. A matching model is selected via identification of the document image. In the case of multiple identifications, a profound analysis of the document type is performed—either automatically or manually. An automatic classifier may be trained with document samples of each of a plurality of document classes or document types where the types are known in advance or a system of classes may be formed automatically without a priori information about types of samples. An automatic classifier determines possible features and calculates a range of feature values and possible other feature parameters for each type or class of document. A decision tree, based on rules specified by a user, may be used for classifying documents. Processing, such as optical character recognition (OCR), may be used in the classification process. | 10-16-2014 |
20140188456 | Dictionary Markup System and Method - A method for providing the appropriate meaning of an entry in a text is described. The method includes the steps of determining if there are alternative meanings of the entry in an electronic dictionary and if there are alternative meanings determining the dictionary markup theme associated with each of the alternative meanings of the entry. Also, the theme associated with the text is determined. For a hierarchical structure associated with themes of entries in the electronic dictionary, the distance between the theme of the text with the dictionary markup theme of the alternative meanings of the entry is compared. Based on the distance between the theme of the text and the dictionary markup theme of the alternative meanings of the entry, the appropriate meaning is selected. | 07-03-2014 |
20140126812 | DETECTING A JUNCTION IN A TEXT LINE OF CJK CHARACTERS - A method for detecting a junction in a received image of the line of text to update a junction list with descriptive data is provided. The method includes creating a color histogram based on a number of color pixels in the received image of the line of text and detecting, based at least in part on the received image of the line of text, a rung within the received image of the line of text. The method also includes identifying a horizontal position of the detected rung in the received image of the line of text and identifying a gateway on the color histogram, wherein the identified gateway is associated with the detected rung. The junction list is updated with data including a description of the identified gateway. | 05-08-2014 |
