摘要： A system and method for pipelined data processing emulates multi-tasking pipelined data processing in a single tasking environment. A host application running in the single tasking environment creates a pipeline of linked data processing tasks to process data from a data source and to provide the processed data to the host application. As each data processing task of the pipeline is created, the task calls an external procedure to obtain header data indicative of the data to be received by the task. Each task alters the obtained header data to reflect the data processing operation to be performed by the task, then the task creates an external procedure callable by other tasks or the host application. The external procedure provides the processed header data from within a task to the calling task or host application. After all tasks of the pipeline are created the host application invokes the pipeline to obtain processed data from the pipeline.

摘要： An image editor for an image processing system has a predefined set of system colors. Color pixel color index values for an image to be edited are stored in an image buffer. A color lookup register bank stores color values in respective registers for a predefined set of system colors. Each buffer index value corresponds to a lookup register having the specified color value. The image is thus displayed by indexing the image pixels to the lookup register bank for the color signal inputs to the display. A mouse is used to designate displayed colors that a user desires to modify in a region of the displayed image. Pixel position data corresponding to the designated colors is detected and hue, saturation and brightness (HSB) values are determined from the stored color values for the designated image pixels. A minimum range of values is determined for each of the HSB variables. A preselected color edit operation is applied to those image pixels having colors corresponding to HSB values within the respective minimum HSB ranges.

摘要： An image file representing at least a portion of a printed document is processed to highlight the differences between foreground material (e.g., text or other characters) from background. The method includes selecting a neighborhood of pixels, determining a weighted average of an attribute values (e.g., luminance) for each pixel, and modifying each pixel's value based on the weighted average. Graylevel scaling, error diffusion, and a bit level conversion are also performed each pixel ends up with either a first attribute value level (e.g., luminance of 0) or a second attribute value level (e.g., luminance of 255).

摘要： Systems and methods are described that facilitate importing scanned image data into a production workflow, in accordance with various features described herein. A plurality of loosely-coupled, dynamically loaded plugins can be defined in a configuration file for a given production scanning job. The plugins can be invoked in response to a trigger with which each plugin is associated, and triggers can be associated with different phases of the production workflow, such as image data acquisition (importation), data filtering (pre-scanning), image analysis (scanning), and metadata processing (post-scanning). In this manner, the overarching scanning architecture need not have direct knowledge of which plugins are triggered, or even present, and custom plugins as well as standard plugins can be provided for each production scanning job.

摘要： A system for electronically distilling information from a business document uses a network scanner to electronically scan a platen area, having a business document thereon, to create a bitmap. A network server carries out a segmentation process to segment the scan generated bitmap into a bitmap object, the bitmap object corresponding to the scanned business document; a bitmap to text conversion process to convert the bitmap object into a block of text; a semantic recognition process to generate a structured representation of semantic entities corresponding to the scanned business document; and a document generation process to convert the structured representation into a structure text file. The semantic recognition process includes the processes of generating, for each line of text having a keyword therein, a terminal symbol corresponding to the keyword therein; generating, for each line of text not having a keyword therein and absent of numeric characters, an alphabetic terminal symbol; generating, for each line of text not having a keyword therein and having a numeric character therein, an alphanumeric terminal symbol; generating a string of terminal symbols from the generated terminal symbols; determining a probable parsing of the generated string of terminal symbols; labeling each text line, according to a determined function, with non-terminal symbols; and parsing the business document information text into fields of business document information text based upon the non-terminal symbol of each text line and the determined probable parsing of the generated string of terminal symbols.

摘要： A novel method is disclosed for laying out a plurality of rectangles onto a bounding box area, where bboxArea represents a total area of the bounding box and totalRectArea represents the sum of the areas of all the rectangles. The method comprises the steps of: first adjusting all rectangles to a specified aspect ratio and then computing a sum of areas of all rectangle intersections (overlap) occurring as a result of said arrangement. Next, the function blackArea=totalRectArea−overlap is used to approximate the black area and all non-overlapping spaces remaining between the arranged rectangles are computed by: WhiteSpace=bboxArea−blackArea. Then, for the current arrangement, an energy function E=whiteSpace+(overlapPenlalty * overlap) is calculated and for each energy function, a state probability function is calculated such that: Pr=exp(−(Enew−Eold)/kT), where Eold is the energy computed for the previously accepted state, Enew is the energy calculated for the current state, T is a control parameter from T0−Tend, and k is a constant. Typically, initial value of T0=100 and Tend=0.0 and the overlapPenalty has an initial value of 100. The value for the control parameter T is subsequently lowered by a fraction of its present value using the relationship: TN+1=TN* 0.95. A random number between 0 . . 1 is then selected and if the random number is less than the value of Pr then the new state Enew is accepted thus new states are always accepted where Enew is less than Eold. The rectangles are again randomly arranged on the bounding box area and the method repeats itself until either Tend is reached or the value of Pr is within acceptable limits.

摘要： A system for organizing a heterogeneous set of page image data, such as including both simple-compressed and JPEG compressed, and/or color and monochrome data, so that the data can be organized as a single, multi-page, TIFF-FX document. Different page images and image components are named according to a simple convention. When a TIFF-FX writer application is applied to the data, the writer application responds to the names of the files and the file hierarchy to write a single, multi-page TIFF-FX document.

摘要： A method and device for describing a complex color raster image as a collection of objects in a hierarchical and device independent format. The purpose of structured imaging (SI) is to expand the scope of a raster image to a collection of individually manipulable component objects. An SI is a hierarchical description of a single output image raster which may be used as one component of a page in a structured document. Objects contributing to the output raster may originate from text, graphics, other rasters or a combination thereof, and all maintain their heritage for selectability and modification. The SI describes not only the source data but also the image processing operations required for rendering the output raster. SI technology supports re-editability, customization and enhancement, automatic image assembly and high performance imaging. Thus, such a model has implications not only in an image editing and processing arena, but also in the filing and printing services used for image handling. Importantly, the present invention describes how Structured Image themes which encapsulates many aspects of a particular document production system to render images into a single entity. A Theme definition includes a signature definition, a set (organization of related themes, and a specific template, background image, or background color for each page. Definitions are, for the most part, loaded from text files at run-time.

摘要： A period-based method for converting digital image data for a plurality of pixels from a first bit depth to a second bit depth includes receiving an input scanline of an arbitrary length comprising digital image data for a plurality of input image pixels. Each of the input image pixels is defined at the first bit depth. The input scanline is divided into a plurality of periods each comprising digital image data for a select number of input image pixels. The period is selected so that the image data for the select number of input image pixels exactly comprises m bytes when defined at the first bit depth and exactly comprises n bytes when defined at the second bit depth, wherein m and n are different integers. For each of the periods in succession, the image data for each of the select number of input image pixels is converted from the first bit depth to the second bit depth. A code generator generates hard-coded conversion operating instructions and a look-up table for specified bit conversion operations and generic conversion operating instructions for all other bit conversion operations.
