摘要： 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.

摘要： Described is a method for identifying text or other information in one or more images and reflowing images of individual elements of text at a word boundary or character boundary on devices of different sizes. The text may be rescaled while retaining the look and feel of the original text. The size may be scaled according to one or more parameters. Text may be captured in a plurality of images and merged together to form a single document or document-like collection. Text may be fully recognized, indexed, sorted and/or be made searchable. Text may be wrapped around objects and features identified as non-text or non-informational elements in an image. Borders or edges between successive elements of text may be smoothed, combined, overlapped and/or blended. Backgrounds of text may be adjusted to make the appearance of successive elements aesthetically pleasing or as close to the original as possible. Fonts may be automatically generated for display of the text on any device in its original form—with breaks in the text at a word or other natural language boundary not found in the original representation of the text.

摘要： 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.

摘要： Embodiments of the invention disclose techniques for processing of machine-readable forms of unfixed or flexible format. An auxiliary brief description may be optionally specified to determine the spatial orientation of the image. A method of searching for elements of a document comprises the following main operations in addition to the operations of preliminary image processing: selecting the varieties of structural description from several available variants, determining the orientation of the image, selecting the text objects, where the text must be recognized, and determining the minimal required volume of recognition, recognizing the text objects, searching for elements of the form. Searching for elements of the form comprises the following actions: selecting a searched element in the structural description, gaining the algorithm of search constraints from the structural description, searching for the element, testing the obtained variants.

摘要： A method is described for creating a scheme for dividing a text line of Chinese, Japanese or Korean (CJK) characters into character cells prior to applying classifiers and recognizing individual characters. Gaps between characters are found as a window is moved down the length of a text line. A histogram is built based on distances from the start of the window to a respective gap as the window is moved. The window is moved to the end of each gap after each gap is found and distances measured. This is repeated until the window reaches the end of the text line. A linear division graph (LDG) is constructed according to the detected gaps. Penalties for certain distances are applied. An optimum path is one with a minimal penalty sum and can be used as a scheme for dividing a text line into character cells.

摘要： Described herein is a method for segmenting a document image into a picture component, a special or significant picture component, and a non-picture component. The non-picture component is compressed and may include character blocks. Separately, picture components are compressed with a lossy algorithm or with a preliminary defined compression ratio. Subsequently, the compressed picture component, significant picture component and the compressed non-picture component are saved in memory or in a storage location so that the document image may be recomposed based on the compressed picture component or compressed significant picture component and the compressed non-picture component.
