| 20080239365 | Masking of text in document reproduction - An apparatus for masking text in a rendered copy of an original document includes a text modification system which is configured to receive a print job from an application and modify the print job in accordance with a print job description, whereby when rendered on an output device, a selected text element is masked. A user interface is configured to receive instructions from a user to build the print job description including instructions for selecting text elements to be masked. | 10-02-2008 |
| 20080243842 | Optimizing the performance of duplicate identification by content - In accordance with the disclosure, there is provided a method for identifying duplicate documents comprising drafting a first document and creating a near unique representative string based on the document content. The method further comprises searching for other documents with the same NRS and selectively assigning a duplicate group identification to the first document, the duplicate group identification is unique if no near unique representative string matches are found, or the duplicate group identification is the same as an associated duplicate document's duplicate group identification that matches the NRS. The method further comprises placing the DGI into a meta-data of the first document and recalling a list of duplicates of a particular document based upon user demand by searching the meta-data and selecting documents using the same DGI. | 10-02-2008 |
| 20080246986 | METHODS AND APPARATUS FOR IMPROVED OPERATION OF NETWORKED PRINTING SYSTEM - Methods and systems are presented for performing one or more printer device management functions in a network, in which affinities between printers are determined from job tracking data to indicate associations between printer devices and user devices, and the affinity data is used to perform one or more printer management functions such as determining printer connections for new or roaming user devices, print job redirection, and identification of underutilized printer device assets. | 10-09-2008 |
| 20080270516 | Method and Apparatus for Controlling Document Service Requests from a Mobile Device - Methods for controlling a document service request involve defining a document service request workflow and redirecting document service requests from the mobile device. In one embodiment, through a short-range connection with a document processing device on a foreign network, a mobile device establishes a secure connection to the mobile device's native network to identify a document stored on a file server operating thereon. Once a document is identified, the mobile device over the secure connection initiates a document service request by requesting an output server operating on the native network to retrieve and convert the identified document into an output-ready format suitable for the document processing device. Upon receipt of the output-ready document, the mobile device resends the output-ready document over a local connection to the document processing device to carry out the document service request. | 10-30-2008 |
| 20100092084 | REPRESENTING DOCUMENTS WITH RUNLENGTH HISTOGRAMS - An apparatus and method are provided for generating a representation of an image which may be used in tasks such as classification, clustering, or similarity determination. An image, such as a scanned document, in which the pixel colorant values are quantized into a plurality of colorant quantization levels, is partitioned into regions, optionally at a plurality of different scales. For each region, a runlength histogram is computed, which may be a combination of sub-histograms for each of the colorant quantization levels and optionally each of plural directions. The runlength histograms, optionally normalized, can then be combined to generate a representation of the document image. | 04-15-2010 |
| 20110078191 | HANDWRITTEN DOCUMENT CATEGORIZER AND METHOD OF TRAINING - 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. | 03-31-2011 |
| 20110137898 | UNSTRUCTURED DOCUMENT CLASSIFICATION - A document classification method comprises: (i) classifying pages of an input document to generate page classifications; (ii) aggregating the page classifications to generate an input document representation, the aggregating not being based on ordering of the pages; and (iii) classifying the input document based on the input document representation. A page classifier for use in the page classifying operation (i) is trained based on pages of a set of labeled training documents having document classification labels. In some such embodiments, the pages of the set of labeled training documents are not labeled, and the page classifier training comprises: clustering pages of the set of labeled training documents to generate page clusters; and generating the page classifier based on the page clusters. | 06-09-2011 |
| 20110150323 | CATEGORIZATION QUALITY THROUGH THE COMBINATION OF MULTIPLE CATEGORIZERS - A system categorizes one or more objects based at least in part upon one or more characteristics associated therewith. A first classifier includes a rule set to determine if each of the one or more objects meets or exceeds a quality threshold. A second classifier, orthogonal to the first classifier, includes a rule set to determine if each of the one or more objects meets or exceeds a quality threshold. In one embodiment, the quality threshold associated with the first classifier and the quality threshold associated with the second classifier are less than a predetermined target threshold. The result for each object of the first classifier is compared to the result of the second classifier. The object is categorized if the result of the first classifier and the result of the second classifier match. The object is uncategorized if the result of the first classifier does not match the result of the second classifier. | 06-23-2011 |
