20080240621 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - An image processing apparatus comprises an operation unit configured to set an input resolution, an image input unit configured to input image information at the input resolution, and an appropriate resolution determination unit configured to determine whether the input resolution is appropriate or not on the basis of the input image information inputted by the image input unit. | 10-02-2008 |
20090060396 | FEATURES GENERATION AND SPOTTING METHODS AND SYSTEMS USING SAME - An image partitioner is configured to find a partition point that divides a received image into four sub-images each having a pre-selected activated pixel count. A recursion processor is configured to (i) apply the image partitioner to an input image to generate a first partition point and four sub-images and to (ii) recursively apply the image partitioner to at least one of the four sub-images for at least one recursion iteration to generate at least one additional partition point. A formatter is configured to generate a features representation of the input image in a selected format. The features representation is based at least in part on the partition points. The features representation can be used in various ways, such as by a classifier configured to classify the input image based on the features representation. | 03-05-2009 |
20090220175 | Adaptive OCR for Books - A system is presented for scanning entire books or document all at once using an adaptive process where the book or document has known fonts and unknown fonts. The known fonts are processed through a verification system where sure words and error words are determined. Both the sure words and error words are sent to OCR training where they are re-OCR'ed and repeatedly verified until they meet a predetermined quality criteria. Characters or words not meeting the predetermined quality criteria receive additional OCR training until all the characters and words pass the predetermined quality criteria. Unknown fonts are scanned and clustered together by shape. Outliers in the shapes are manually keyed-in. Those symbols that are manually classified go to OCR training and then to the known type optimization process. | 09-03-2009 |
20090238494 | SYSTEM FOR CHARACTER RECOGNITION - A system for character recognition from a sheet bearing a plurality of characters, has a base for supporting the sheet, an image input device for taking an image of each of the characters on the sheet, a handle for supporting and manipulating the image input device, an axis, a sphere part, a receiving part fixed to the base and having a hollow for accommodating the sphere part, one of the sphere part and the hollow having a plurality of depressions and the other having a projection for fitting into one of the depressions, whereby when a view angle of the image input device is changed to point a location of each of characters on the sheet by manipulation of the handle, the image input device is rotated about the axis and a character recognizing unit for recognizing the character on the image taken by the image input device. | 09-24-2009 |
20090252439 | METHOD AND SYSTEM FOR STRAIGHTENING OUT DISTORTED TEXT-LINES ON IMAGES - 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. | 10-08-2009 |
20100086236 | METHOD OF IMAGING POSITION-CODING PATTERN HAVING TAG COORDINATES ENCODED BY SUCCESSIVE SUBSEQUENCES OF CYCLIC POSITION CODE - A method of decoding a position-coding pattern disposed on a surface of a substrate. The method comprises the steps of: (a) operatively positioning an optical reader relative to said surface and capturing an image of a portion of the coding pattern, the coding pattern comprising: a plurality of tags, each tag encoding a w-bit subsequence of a cyclic code sequence having a length n and a dimension k, the w-bit subsequence mapping to a corresponding coordinate codeword for the tag; (b) sampling a windowed subsequence contained in the imaged portion; (c) identifying a coordinate codeword corresponding to the windowed subsequence; and (d) determining a position of the optical reader from the coordinate codeword. The imaged portion has a diameter of more than one tag diameter and less than two tag diameters, and n>w>k. | 04-08-2010 |
20130114914 | SIGNATURE MARK DETECTION - A system and method for detection of signature marks in documents are provided. The method includes selecting candidate text objects in document pages and identifying a sequence of elements therein. The sequence has a numbering pattern including an incremental part and optionally a fixed part. Missing elements between two detected elements of the sequence are permitted. For an identified sequence, a model of the sequence is generated, which includes the numbering pattern of the sequence, an increment, which is computed based on the distance between pages on which consecutive elements of the sequence are identified, a valid sequence having an increment of greater than 1, and a first page, which corresponds to a page of the document on which the sequence starts. The sequence is then validated with the model, allowing elements of the sequence in the pages of the document to be identified as signature marks. | 05-09-2013 |
