摘要： The present invention is a method and apparatus for automatically detecting the characteristics of a document object placed on the platen of a digital copier or similar scanning system. The invention accomplishes the detection by processing a digitized image in a highly efficient manner using binary moments, and using the moments characterizes the shape of a boundary about the object. Once determined, the shape of the object may be employed to further process the image to automatically crop, derotate, and register the image at a predefined location in an output image suitable for rendering on a document substrate.

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： 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.

摘要： A relevance based print integrity method includes comparing current raster image data that define a document to be printed with golden raster image data that define a previous version of said document with a known (perfect) quality. A plurality of differences between said current raster image data and said golden raster image data are calculated, and each of the differences is processed to determine a relevance value of the difference and to assign the relevance value to the difference. The method includes generating and storing a list of the differences, wherein the list is ordered in terms of the relevance value assigned to each difference. The difference list is presented to a user textually or graphically and/or is used to control or interrupt printing operations.

摘要： The present invention is an intelligent scanning system for processing a digital input image to automatically characterize a plurality of objects therein. The system then employs the characterizations as the basis for rudimentary image editing operations so as to produce a digital document. In the digital document, the objects may be derotated, shifted, cropped or otherwise aligned in a predetermined fashion in accordance with a template. The scanning apparatus of the present invention not only enables the scanning of a plurality of objects, but does so in an intelligent manner so as to enable further processing and manipulation of the images associated with the objects to create an output document.

摘要： A control system for pipelined image processing emulates a multi-tasking environment using a single tasking application. A number of predefined image processing tasks are provided in a library. When a host application needs a processed image from an image source, the host application creates a pipeline of initialized instantiations of one or more of the tasks from the library. When the host application invokes the pipeline, the first data request for the heater of the image travels upstream in a first channel. The processed image header is returned down the first channel. Then a data request for scanlines of image data is sent upstream in a second data channel. The data request ripples upstreamwardly to the upstream-most instantiation of one of the tasks from the task library. The upstream-most instantiation of a task obtains a scan line from an image data source and returns it downstreamwardly to the host application in the second channel. Each instantiation of a task from the task library further operates on the image data. Once all of the scanlines have been processed, the memory allocations and data structures created during initialization are released to free up that memory.
