摘要： An artifact removal and quality assurance method and system for digital images, wherein a document comprising at least one printed page is scanned or the original image data are otherwise input. The input digital image data are segmented into components as to content type. The components are classified as either information or noise components. An information component image defined by the information components and a noise component image defined by the noise components are generated and displayed to the user. The user inputs quality assurance input data to indicate zero or more improperly classified components and any improperly classified component is reclassified. The component images are then regenerated and displayed to account for the reclassified component(s). The reclassified component is moved as a unit in real time as viewed by the user from an original location in one of the component images to a corresponding location in the other of the component images. Both component images are saved or otherwise output as desired.

摘要： The teachings as provided herein relate to a watermark embedded in an image, and methodology for same, that has the property of being relatively indecipherable under normal light, and yet decipherable under UV light. This fluorescent mark comprises a substrate containing optical brightening agents, and a first dot design printed as an image upon the substrate. The first dot design has as a characteristic, the property of strongly suppressing substrate fluorescence. A second dot design having a property of providing a differing level of substrate fluorescence suppression from that of the first dot design such that when rendered in close spatial proximity with the first dot design image print, the resultant image rendered substrate suitably exposed to an ultra-violet light source, will yield a discernable image evident as a fluorescent mark.

摘要： A method for creating a differential gloss image includes providing first and second anisotropic halftone structures. The first and second anisotropic structures have different orientations. One of the first and second anisotropic structures is applied to image data in a first region of an image to be halftoned. The other of the first and second anisotropic structures may be applied to image data in a second region of an image to be halftoned. A mixture of the first and second anisotropic structures is applied to image data in a third region of the image to be halftoned, whereby when printed, the three regions each have a gloss characteristic which differs from that of the other two regions.

摘要： Disclosed is a method to detect streaks in the scanned documents. The principle of this method is that the profiles of streaks change very little from line to line, while profiles of other thin lines, as content of scanned documents, usually vary in a degree. Therefore, each scan-line can be searched for streak profiles. Once such a profile is detected, it is compared with a profile stored in a buffer, which represents a dynamic average of previously recorded scan-lines. If a stable streak profile is detected and lasted for a certain length, say one inch, the streak alarm can be turned on and a corresponding correction process can be applied for streak removal. With a limited buffer increase and without any major hardware modification, the proposed method can detect occurrence of streaks at run time of the scanning process.
摘要翻译：公开了一种检测扫描文档中的条纹的方法。这种方法的原理是，条纹的轮廓从一行到另一方变化很小，而作为扫描文档的内容的其他细线的轮廓通常在一定程度上变化。因此，可以搜索每条扫描线的条纹轮廓。一旦检测到这样的轮廓，就将其与存储在缓冲器中的轮廓进行比较，这表示先前记录的扫描线的动态平均值。如果检测到稳定的条纹轮廓并持续一定长度，例如一英寸，则可以打开条纹报警，并且可以应用相应的校正过程来进行条纹去除。在缓冲区有限的情况下，没有任何主要的硬件修改，所提出的方法可以检测扫描过程运行时的条纹发生。

摘要： The present invention relates to expanding the range of image densities over which the manipulation of differential gloss as may be inherent in halftoned images may be achieved. By selectively applying halftones with anisotropic structure characteristics which are significantly different in orientation while remaining identical in density, a gloss image may be superimposed within an image without the need for special toners or paper. This technique may be enhanced across low and high density areas by application of clear toner to expand the range of image densities over which a desired glossmark image will bear an effect.

By selectively applying halftones with anisotropic structure characteristics which are significantly different in orientation while remaining identical in density, a gloss image may be superimposed within an image without the need for special toners or paper. This technique may be enhanced across low and high density areas by application of clear toner. Further, in color systems, light color toner may be applied to low density image areas and dark under-color applied in high density image areas, to expand the range of image densities over which a desired glossmark image will bear an effect.

摘要： A printing apparatus and method for duplex printing a document having a show-through watermark wherein the watermark is comprised of first and second images on both sides of the document. The images comprise stoclustic halftone screens having a substantially common registration wherein the second image is relatively shifted from the first image for forming an associated overlay pattern between the first and second images resulting in a recognizable pattern comprising the watermark upon illumination by a show-through light source. The watermark is unrecognizable from either image alone upon illumination from a front light source. The relative shifting can be implemented by either phase, frequency or angle shifting between the front and back side images.

摘要： A system and method for classifying an image block of a printed image into contone, halftone, or error diffusion classes, includes scanning the printed image; selecting an n by n block of pixels from the scanned image in a luminance channel; calculating an array of DCT coefficients of the pixel block, wherein the calculated DCT coefficients are representative of spatial frequency and spatial orientation of the pixel block; comparing the array of DCT coefficients with an array of predetermined values, wherein the array of predetermined values are indicative of contone, halftone and error diffusion classes; and determining the image classification of the pixel block based on the comparison of the DCT coefficients with the array of predetermined values. If the image is determined to be halftone, then the method further evaluates the DCT coefficients to determine the frequency of the halftone screen.
