    摘要: An image processing system such as a multi-function device (MFD) with an “e-reader” mode is disclosed. The e-reader mode can be activated by a user from the MFD user interface, or automatically detected by the system if the mode is set to “auto.” Once in e-reader mode, the system automatically locates the area corresponding to the e-reader screen, crops it, de-skews it when necessary, and enhances the image. In addition, N-Up (printing several pages of content on one physical page) may be applied if users desire. The enhancement adjusts background color, boosts the contrast, and de-blurs the image when necessary. Two embodiments of enhancement are presented. The first one performs Tone Reproduction Curve (TRC) adjustment and possible de-blurring on the entire screen area. The second one segments the screen area into three kinds of objects (text/picture/background). Different TRCs are applied to enhance the objects.

    摘要: A system resizes content within a document that includes a document segmenter that receives a document that contains content. The document segmenter analyzes the content within the document and segments the content into a plurality of object types. An object priority applicator determines a class value associated with each object type. A location scaler identifies a datum point for each object type within the document, wherein each datum point maintains a relative location to one another regardless of document resizing. An object sizing component resizes each object based at least in part upon the class value.

    摘要: A method is provided for embedding miniature security marks within documents and images, utilizing a mark parameters database, graphical user interface, and detection simulator. The method includes predicting detection error rates for each pixel location of a host image, defined as a digital representation of at least one recipient of the miniature security marks. The detection error rates for each pixel are displayed with the host image on a graphical user interface and the desired miniature security mark locations are selected. At least one set of miniature security mark parameters is identified, with the parameters being mark parameters that enable determination of an optimized balance between detectability and visibility of the miniature security marks. The host image with the miniature security mark is displayed on the graphical user interface for review and adjustment by an operator.

    摘要: A method for embedding coded information in a document border includes encoding information as a plurality of data carrying dot pair patterns where each dot is too small to be visually noticeable. For each page of a document to be rendered, the method includes determining whether the border area is blank. If found not blank the border area is cleared. Each of the plurality of data carrying dot patterns is embedded in the blank border area of the document page. The document page with the embedded data carrying dot patterns is then rendered, where each data carrying dot is too small to be visually noticeable.

    摘要: Systems and methods are described that facilitate determining an original document format for a scanned document by analyzing a bitmap thereof. Text objects are extracted from the document, binarized, and segmented to identify text. Page orientation and text size are used to distinguish between a slideshow-type document, and a word processing or spreadsheet-type document. To further distinguish between the word processing and spreadsheet types, text column structure and count is analyzed.

    摘要: In preparation for rendering respective portions of a document via a respective plurality of engines, objects within the document are identified and characterized. A determination is made as to whether gamut variations between the engines might result in objectionable variations in the appearance of rendered versions of identified objects having similar characteristics. For those objects within the document for which the determination is made that variations might be objectionable, a target gamut is selected to be an intersection gamut of the engines to be used to render the document. For those objects within the document for which the determination is made that variations would be unobjectionable, the target gamut is selected to be that of selected individual engines. A system for selecting target gamuts for objects within a document can include an object identifier, a characteristic identifier and a gamut selector.

    摘要: A method for enhancing color fidelity in multi-reproduction, includes scanning an image to be reproduced, wherein the image contains an invisible digital watermark including color information; decoding the color information contained in the watermark; comparing the decoded color information with the scanned image; generating a correction table from the differences between the decoded color information and the scanned image; and performing color correction on the scanned image using the correction table. This method confines the color error to one generation, even when copies go through multiple reproduction.
