摘要:
A method and system for creating guilloché base pattern with two-dimensional periodicity in a plurality of replicate patterns is shown wherein the creating can be assessed in real-time for pattern acceptability by a user. A base pattern is set on an imaging device in vector space relative to a set of predetermined pattern nodes. The base pattern is modulated via a user interface by adjusting positions of the pattern known for selectively controlling curve shapes of the pattern. A guilloché mark is illustrated by display on the imaging device of the adjusted base pattern and a compilation of associated replicate patterns for user assessment of the mark.

A text-like data representation technique and a text-like data representation apparatus are disclosed that may: acquire image data from a scanned image; segment text regions from the image data; further extract each connected component in the text regions; form clusters based on the connected components; group each connected component in the text regions into one of the clusters with similar or identical characters; generate a high-resolution representative for each cluster; generate a vector representation for each high-resolution representative; and code the text as text data by associating each connected component with its vectorized high-resolution representative, and location in the document.

A system for generating a security mark includes a data reception component that receives information. A security mark generation component in communication with the data reception component generates at least one security mark configuration based at least in part upon the received information. The at least one security mark configuration includes at least one simulation mark which resembles a natural feature. An application component applies one configuration of the at least one security mark configurations to a recipient. The applied security mark configuration obeys at least one rule whereby the security mark is distinguishable from the natural feature which it resembles by a system for detection of security marks.

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 method of defining a glyph font character representing an input binary code includes defining a first portion of a matrix using an input binary code including a plurality of input bits. A second portion of the matrix is defined by performing a transformation on the input binary code so that the second portion of the matrix includes a plurality of transformed bits. A glyph character is derived that corresponds to the matrix. The glyph character is defined by a plurality of components corresponding in location to said bits of said matrix, wherein the components of the glyph character comprise a first component (e.g. a forward slash /) that corresponds to and represents a “1” bit of the matrix and second component (e.g., a backslash \) that corresponds to and represents a “0” bit of the matrix. The transformation operation includes a NOT operation or other logic operation, and includes a shift operation. The transformation can be repeated to derive additional portions of the matrix by transforming the group of bits of the preceding matrix portion. The glyph characters corresponding to alphabet characters are each defined as a bitmap and are saved as Postscript Type 3 font.

摘要:
A light compression method that error diffuses image data provided with luminance and chrominance channels. During error diffusion, a higher number of bits are allocated to the luminance channel. A decompression method for the image data based on sigma filtering is also provided. By manipulating the bits in the luminance and chrominance color spaces, the image output quality may be increased in reconstructed images.

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.

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.

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.
