摘要： A printing system accurately prints proprietary marks and selected colors. A dictionary of recognizable patterns and defined colors corresponding to the proprietary marks and selected colors is linked to a user interface wherein a user may designate a location within a document and at least one of the proprietary marks with defined colors from an accessible menu. A processor associates the defined colors with the image at the specified location and generates a printer signal representative thereof. Alternatively, the processor includes a pattern recognizer for identifying recognizable patterns within a document. The patterns have a likeness to defined patterns within a pattern dictionary and can be converted to the defined patterns for display or imaging.

摘要： Text, images, and/or graphics of electronic documents should be organized and laid out in a two-dimensional format for presentation to the viewer. The best such layout depends upon the content present, the creator's intent, the output device, and the viewer's interests. To analyze the qualitative nature of the layout in quantifiable terms, the electronic document is measure using various quantifiable factors; such as, balance, uniformity, white space management, alignment, consistency, legibility, etc.; that impact a qualitative nature of a document. Such quantifiable factors are then used to quantize the aesthetics, ease of use, eye-catching ability, interest, communicability, comfort, and convenience of the document.

摘要： A method and apparatus selectively displays a processor generated image in accordance with user instructions detected by a processor from a processor viewing device disposed to view a real reference item controlled by the user. The real item, preferably a page of paper, is disposed as a reference frame for an electronic image to be displayed. The orientation of the page is identified by the system. Corresponding real world coordinates are computed for the captured image and compared with predetermined standards to verify the nature of the object.

摘要： A method of smoothing edges of an input image is provided for use in connection with an image rendering engine that supports two opposing intensity levels and a range of intermediate intensity levels there between. The method includes sampling scan lines from the input image. Each scan line includes an array of pixels, and each pixel possesses one of the two opposing intensity levels. Simultaneously a plurality of the scan lines are buffered. Thereafter, the method includes detecting defined patterns in an unbounded region within the buffered scan lines. Finally, intensity levels of selected pixels are adjusted to intermediate intensity levels in response to the defined patterns detected.

摘要： The present invention provides a method for filtering noise out of an image. The image is constructed of pixels having varying intensity values. The method includes reading the intensity values for pixels within a neighborhood of an object pixel. Thereafter, a number of intensity values are selected from the read intensity values. The selected intensity values are those closest to the intensity value of the object pixel. A median value for the selected intensity values is then calculated. Finally, the median value is assigned as a new intensity value for the object pixel.

摘要： A method of combining a foreground image and a background image includes scaling up a pixel of interest, which is positioned along an edge between a subject and a key colored backing, into a plurality of edge subpixels. The pixel of interest is included in a digital antialiased foreground image. A corresponding pixel of a digital background scene is also scaled up. The corresponding pixel is associated with the pixel of interest and is scaled up into a plurality of background subpixels. For each of the edge subpixels, if a color of the edge subpixel matches the key colored backing, a respective new color of the edge subpixel is determined as a function of one of the background subpixels, which is associated with the edge subpixel. Also, the new color is stored to the edge subpixel. After all the subpixels have been evaluated, the edge subpixels are scaled down to a new pixel of interest.

摘要： Systems and methods for determining the texture of the images to be processed are provided. An image data manager is provided that is capable of generating summed-area tables to be applied in texture mapping for texture that have no special direction or orientation, by generating summed-area tables for areas that best approximate circles. The image data manager uses the generated summed-area tables to process the image data. The summed-areas tables applied include a hexagon and an octagon. Accordingly, problems in processing images having textures that have no special direction or orientation, are reduced or eliminated.

摘要： A method and system compensates for the line width growth or shrinkage in an image rendering system that supports high-addressability. The amount of width adjustment can be a function of the line width. The method is applied after rendering, to the sub-pixel, bit patterns and is compatible with antialiasing and other sub-pixel rendering techniques such as half-bitting. The method and system also require less scan buffering for marker line width compensation than conventional methods. More specifically, the method and system require N+3 scans to detect and adjust widths up to N pixels for leading edges or trailing edges rather than the 2N+3 necessary conventionally. Moreover, the detection and adjustment of widths up to N pixels may be performed for both leading edges and trailing edges using a buffer that can handle 2N+3 scans.

摘要： A document containing colored text is reproduced in a way to preserve the color intent if the reproduced document is copied on a black-and-white device. For small text, the fact that it is colored, is conveyed by reproducing it bold, and for medium size text, by reproducing it outlined. For large text, both the fact that it is colored and the color used can be conveyed by filling the interior of the characters with patterns that correspond directly to the color.
