  • Publication number: 20110078191
    Abstract: A method and an apparatus for training a handwritten document categorizer are disclosed. For each category in a set into which handwritten documents are to be categorized, discriminative words are identified from the OCR output of a training set of typed documents labeled by category. A group of keywords is established including some of the discriminative words identified for each category. Samples of each of the keywords in the group are synthesized using a plurality of different type fonts. A keyword model is then generated for each keyword, parameters of the model being estimated, at least initially, based on features extracted from the synthesized samples. Keyword statistics for each of a set of scanned handwritten documents labeled by category are generated by applying the generated keyword models to word images extracted from the scanned handwritten documents. The categorizer is trained with the keyword statistics and respective handwritten document labels.

  • Patent number: 7916972
    Abstract: A form reader includes a landmarks extractor configured to select textboxes of a converted document as form landmarks based on textual characteristics. A set of positional constraints constrain the form entries relative to the identified form landmarks. A constraints solver selects textboxes of the converted document as form entries by solving the set of positional constraints respective to a set of facts including the selected form landmarks and converted document. In some embodiments, the constraints solver includes a query engine configured to (i) construct a query in a logic programming language setting forth the set of positional constraints and the set of facts and to (ii) input said query to a logic programming language query solving engine and to (iii) receive a response from the query solving engine responsive to the input.

  • Patent number: 7917049
    Abstract: A control method for monitoring the cleaning performance of a single or multiple blade xerographic cleaning subsystem includes looking at the photoreceptor post-cleaner with a full width array sensor and adjusting the blade load on the photoreceptor to the minimum required to maintain effective cleaning. Blade load is adjusted using a stepper motor. Monitoring of cleaning failures can be done during non-print time, when a toner patch is developed to evaluate cleaning. Re-adjustment is needed periodically since environmental stresses can change, and the blade ages due to set and wear. Two toner patches at the ends of the blade with two stepper motors can be used to assure the same load from end to end.

  • Patent number: 7914000
    Abstract: A method and system for performing sheet registration are disclosed. Output values for a sheet may be identified within a reference frame. A difference between each output value and a corresponding desired output value may be determined. Input values may be determined based on at least the differences. State feedback values may be determined based on information received from one or more sensors. Jerk values may be determined for multiple drive rolls based on the input values and the state feedback values. A desired angular velocity for each drive roll may be determined based on the corresponding jerk value. A motor voltage may be determined for each drive roll that tracks an observed angular velocity value to the desired angular velocity value. The jerk values may create a linear differential relationship between the input values and the output values. The steps may be performed multiple times.

  • Patent number: 7916893
    Abstract: An image processing apparatus includes an image capturing section, a marker-image defecting section, a judging section and an output section. The image capturing section captures at least a part of a target image, which includes a plurality of marker images and a recognition target range defined by the plurality of marker images, to acquire a captured image. The marker-image detecting section detects the marker images from the captured image. The judging section judges based on a detection result, whether or not the recognition target range is included in the captured image. When the judging section judges that the recognition target range is not included in the captured image, the output section outputs guidance for capturing the recognition target range.

  • Patent number: 7913999
    Abstract: A system, method, and resulting resilient belt type sheet compiler with a mixed sheet length mode is provided. The device includes a resilient belt transport for sequentially feeding sheets from a sheet inlet to a compiler tray, the compiler tray having a lead edge stop and a trail edge wall. A monitoring means is positioned proximate to the trail edge wall for detecting a lead end and a trail end of sequentially fed sheets from the sheet inlet to the compiler tray. A sheet brake, responsive to the monitoring means detecting a short sheet, selectively stalls the detected short sheet until a lead end of a subsequent sheet is detected by the sensor or subsequent sheets are absent.
