摘要： A method for run-time streak removal from a scanned image includes providing a scan line of image data from the scanned image; detecting corrupted data within the scan line; evaluating image data located in a neighborhood before and after the corrupted data on the scan line; if the evaluated image data in the neighborhood is smooth, replacing the corrupted data with image data determined by a linear interpolation process; and else if the evaluated image data in the neighborhood is not smooth, replacing the corrupted data with image data determined by the linear prediction process. Various techniques can be used to evaluate the image data located in the surrounding neighborhood. For example, a filter selection step may be used based on prediction discrepancies.

摘要： The present disclosure relates to providing a user interface for the effective generation of differential gloss images. The user is instructed to indicate the base primary image data, and the desired gloss image data. This data may be displayed for verification and position adjustment by superimposition of the gloss image data upon the base image data. In an alternative, the placement information may be inferred from the position of originals upon the scanner or copier platen and the result may or may not be displayed. By selectively applying halftones with different anisotropic structure orientation characteristics to the base primary image data as directed by the desired gloss image data, a differential gloss image file or hardcopy may be provided.

摘要： A method of embedding digital watermarks such as logos, letters or other types of user information into printed documents using different halftone textures. By alternating different halftone methods, such as different halftone screens or different error diffusion algorithms during the halftoning process, digital watermarks can be embedded into the input images at run time. The actual watermark is created by changing—on a pixel basis—the halftoning algorithm that is used in rendering the input image. No modifications to the input image are needed and the image data is reproduced correctly, but with a visible seem between different halftoning techniques.

摘要： The present invention relates to the expedient supply of differential gloss or other correlation mark text into a document image via a font definition, particularly as when desired in the employ of rendering variable data. A font character is selected and sub-sampled. The sub-sampled result is then scaled up into a full size result. A first halftone cell having a first anisotropic structure orientation is selected and applied to the full size scaled font result while a second halftone cell having a second anisotropic structure orientation is applied to the surrounding background around the full size scaled font result to create a gloss font or other correlation mark character. This full gloss font character or correlation mark character is then stored as a font representation as callable by the digital front end of a printing apparatus.

摘要： Provided herein are teachings directed to using duplex printing on transparencies to create auto-stereoscopic enhancement to rendered images as viewed in a “see-through” manner. By choosing different halftone structures, differing by having different spatial frequencies for each of the two sides of a transparency, a moiré pattern resulting due to halftone overlapping can be observed. On one side of the transparency is provided a uniform halftone with a selected median spatial frequency as printed. On the other side, the image for enhanced rendering consisting of two partitions is printed: that partition which is to be perceived as the background is printed using a halftone with spatial frequency equal to the median plus some delta x, while the other image partition is printed using a halftone with a spatial frequency equal to the median minus the same delta x. The spatial frequency difference between the halftones on two sides creates a corresponding shift-magnification factor M. The moiré produced by the two partition print images as visually located appear in two separate spatial planes as separated by the transparency, with an amplified total depth of the shift-magnification factor M times the thickness of the transparency. This yields a moiré stereoscopic pattern for the desired image partition as clearly discernable to the human eye with out aid of lenses or other means.
摘要翻译：这里提供的是涉及在透明胶片上使用双面打印来创建对以“透视”方式观看的渲染图像的自动立体增强的教导。通过选择不同的半色调结构，通过对透明体的两侧的每一侧具有不同的空间频率而不同，可以观察到由于半色调重叠而导致的莫尔图案。在透明度的一面上提供具有所选中位数空间频率的均匀半色调。另一方面，打印由两个分区组成的增强渲染图像：使用空间频率等于中值加一些delta x的半色调打印要被感知为背景的分区，而另一个图像分区是使用具有等于中值减去相同δx的空间频率的半色调打印。两侧半色调之间的空间频率差产生相应的移位放大系数M.由视觉定位的两个分区打印图像产生的云纹出现在由透明度分开的两个单独的空间平面中，放大的总深度移位放大倍数M倍透明度的厚度。这样就可以通过透镜或其他方式帮助人眼清晰地识别所需图像分区的莫尔立体图案。

摘要： A method is provided for rendering a color image with a plurality of separations with a multi-level successive-filling halftoning process using a single screen for a plurality of separations. For a separation to be processed, first, from the possible multiple levels for the separation, the set of levels that would be used and the number of dots corresponding to the different levels are decided. These decisions are based on the input level for the separation and input levels for the prior process separations. The location of the dots to be printed for the different levels for the separation is then decided by using the halftone screen, while simultaneously taking into account the placement of printed dots for the prior separations. The selection is done so as to best disperse dots and minimize overlap.

摘要： The invention provides methods for using single-cell non-orthogonal cluster screens to satisfy the moiré-free conditions for four-color halftoning. The selection of these single-cell halftone screens is determined by identifying combinations of four of the halftone cells which satisfy moiré-free conditions provided in the respective frequency equations. Constraints may be applied and the combinations not meeting such constraints can be removed.

摘要： A method for automatically classifying a printed image, includes scanning the printed image; selecting an n by n block of pixels from the scanned image; calculating an array of DCT coefficients of the pixel block, wherein the array of calculated DCT coefficients are representative of spatial frequency and spatial orientation of the pixel block; comparing the DCT coefficients with an array of predetermined values, wherein the array of predetermined values are indicative of different image marking processes used to produce printed images; and determining an image marking process used to create the printed image based on the comparison of the DCT coefficients with the array of predetermined values. The array of DCT coefficients may be sampled into a feature set and the feature set provided to a neural network to output the determined image marking process.
