  • Patent number: 10839245
    Abstract: A structured document analyzer that associates keys and values in structured documents based on key, value, and key-value container bounding boxes. A trained machine learning model analyzes images of structured documents to determine bounding boxes for keys, values, and key-value containers in the images with confidence scores for the classifications. For each image, duplicate bounding boxes are removed, and then a set of key-value containers are selected and sorted based on the confidence scores. For each key-value container, a best key and value are determined for the container based on overlap of the key and value bounding boxes with the container bounding box and the confidence scores. Optical character recognition may be performed on the image to determine text for the keys and values.

    Abstract: Systems and methods for computationally efficient and precise transformation recovery using two image frames are provided. A key image frame and a tracked image frame are selected from a series of image frames, a plurality of points on the key image frame are selected, and the plurality of points are then projected onto the tracked image frame to produce a number of corresponding points. Then, for each corresponding point, a patch of pixels is defined centered on the corresponding point. Each pixel of the patch is reprojected back onto the key image frame to identify a reprojected pixel in that image frame. An intensity value for each reprojected pixel is determined and each patch is parameterized. A normal equation for each patch is determined and then solved for the transformation.

    Abstract: The current application is directed to methods and systems that convert document images, which contain Arabic text and text in other languages in which symbols are joined together to produce continuous words and portions of words, into corresponding electronic documents. In one implementation, a document-image-processing method and system to which the current application is directed employs numerous techniques and features that render efficiently computable an otherwise intractable or impractical document-image-to-electronic-document conversion. These techniques and features include transformation of text-image morphemes and words into feature symbols with associated parameters, efficiently identifying similar morphemes and words in an electronic store of standard-feature-symbol-encoded morphemes and words, and identifying candidate inter-character division points and corresponding traversal paths using the similar morphemes and words identified in the word store.

  • Patent number: 9417286
    Abstract: A system and method for image enhancement associated with scan generators is provided. For example, a source stimulates a device under test (DUT) at electrical interconnects. An internal clock of the DUT is synchronized with the scan rate of the source to reduce the noise of the output signal and enhance a resultant image. A phase adjustment is effected to further reduce the noise in the signal. The synchronization and the phase adjustment seek to ensure that the data is collected at uniform times relative to the reference signal and thereby reduce the noise introduced into the system, by such offsets. Post-scan processing increases the signal-to-noise ratio through averaging techniques. Using a pixel overlay algorithm the averaged data is transformed into a 2-D array and the image of the DUT reconstructed.

The Character chopper component is configured to produce a set of (possibly curved) chop-lines which divide a bitmap of any given word into its individual character or glyph candidates. Cases where an input bitmap contains two separate words are handled by marking a place where those words should be split. The character segmentation algorithm computes the set of vertically oriented, curved chop-lines by considering glyph and background colors in a given word bitmap.

  • Patent number: 8472719
    Abstract: A method of identifying stricken-out characters in handwriting, comprising parsing a scanned image into regions and objects, defining objects containing handwritten characters, applying structural or feature classifiers for primary character recognition, applying one or more supplemental feature classifiers preliminarily trained by strike-out characters, and identifying a stricken-out character if any. The stricken-out character may be further examined by special procedures, either automated or manual.

  • Patent number: 8467566
    Abstract: A method is provided for authenticating an image printed at a predefined print resolution or in accordance with a predetermined print grid. The method includes the steps of scanning the image to produce digital data and segmenting the data into first and second groups corresponding, respectively, to first and second predefined sections of the image. Next, a determination is made concerning the anticipated spatial position of select columns of digital data from each of the first and second groups of data. By examining the data, differences may be identified between the anticipated and actual spatial position of the columns, to determine the authenticity of the image. The identified differences which may include (i) a rotary/linear displacement in the actual spatial position of the select columns. (ii) a change in beat frequency between sections of the image, and/or (iii) a phase shift in a beat frequency.

  • Patent number: 8467607
    Abstract: Methods and systems for processing an image to create an object model are disclosed. In accordance with one embodiment, each segment of the image is assigned to a respective bin of a bounding box. For each bin of the bounding box, the value of a feature for the bin is computed based on the values of that feature for each of the segments assigned to the bin. An object model is then created based on the values of the feature for the bin.

  • Patent number: 8457443
    Abstract: To handle static text and logos in stabilized images without destabilizing the static text and logos, a method of handling overlay subpictures in stabilized images includes separating an existing overlay subpicture from an input image to generate a separated overlay subpicture and a separated input image. The separated input image is stabilized to form a stabilized image. The separated overlay subpicture is then merged with the stabilized image to obtain an output image.

  • Patent number: 8416244
    Abstract: A graphics or image rendering system, such as a map image rendering system, receives image data from an image database in the form of vector data that defines various image objects, such as roads, geographical boundaries, etc., and textures defining text strings to be displayed on the image to provide, for example, labels for the image objects. The imaging rendering system renders the images such that the individual characters of the text strings are placed on the image following a multi-segmented or curved line.

  • Patent number: 8384917
    Abstract: A method, system, and computer program product for font reproduction in electronic documents are provided. The method includes: receiving an image of a printed document; extracting pairs of consecutive characters from the image of the printed document; storing the extracted pairs as images of the characters; and reproducing the printed document as an electronic document with text of overlapping extracted character pair images. Extracting pairs of consecutive characters includes extracting adjacent horizontal characters, extracting spaced horizontal characters, and extracting spaced vertical characters. Reproducing the printed document as an electronic document includes reproducing the spacing between words and between lines using the spaced horizontal characters and the spaced vertical characters as anchors in the reproduced document.

  • Patent number: 8363947
    Abstract: A method, system and computer program product for recognizing cursive and non-cursive handwriting. The invention comprises capturing a handwritten character as an image of pixels, partition the image into a plurality of segments each having a pixel ratio of the number of pixels in the segment divided by the total number of pixels in the image, and compare the pixel ratio for each segment to a value range associated with a corresponding segment of a reference character. The handwritten character is recognized as the reference character if more than a predetermined number of the segments in the image have the pixel ratios within the respective value ranges of the reference character.
