摘要： A fluorescence-based correlation mark is included in a printed document by encoding the correlation mark as phase shifts in the yellow halftone image only of a printed color document. The correlation mark transparency key is likewise printed using only yellow colorant or can be printed in black or with another colorant or mixture of colorants that will appear dark or black when subjected to UV illumination. UV illumination of the document without use of the transparency key, and use of the transparency key without UV illumination of the document are insufficient to reveal the fluorescence-based correlation mark. UV illumination of the document while the transparency key is overlaid with the document will allow the correlation mark to be perceived.
摘要翻译：基于荧光的相关标记通过将相关标记编码为仅打印的彩色文档的黄色半色调图像中的相移而被包括在打印文档中。相关标记透明度键同样地仅使用黄色着色剂打印，或者可以以黑色印刷，或者与其它着色剂或着色剂混合物一起印刷，当经受紫外线照射时，其将显示为黑色或黑色。使用紫外线照射文件而不使用透明度键，并且使用透明度键不使用紫外线照射文件不足以揭示基于荧光的相关标记。当透明度键与文档重叠时，文档的UV照明将允许感知相关标记。

摘要： A method for encryption of a digital watermark by intelligent halftoning includes receiving image data that define at least a portion of a document to be printed in terms of at least three halftone images corresponding respectively to three printing colorants, each of the three halftone images comprising a plurality of halftone cells. The image data are modified by phase-shifting some of the halftone cells of at least one of the halftone images relative to the other halftone images to encode a watermark within the portion of the document such that the at least one phase-shifted halftone image includes a phase-shifted region and a non-phase-shifted region. The modified image data are used to print the portion of the document on a substrate that will fluoresce when subjected to UV illumination. The printed portion of the document includes a first printed pattern resulting from the phase-shifted region and a second printed pattern resulting from the non-phase-shifted region. The first and second patterns of the printed portion of the document appear substantially similar when the portion of the document is viewed in visible light, and appear dissimilar when the portion of the document is viewed in UV light such that the watermark encoded in the modified image data is perceptible when the portion of the document is viewed in UV light and is hidden when the portion of the document is viewed in visible light.
摘要翻译：通过智能半色调对数字水印进行加密的方法包括接收图像数据，该图像数据限定要分别对应于三个打印着色剂的至少三个半色调图像要打印的文档的至少一部分，三个半色调图像中的每一个包括一个多个半色调细胞。图像数据通过相对于其他半色调图像相移至少一个半色调图像的半色调单元来对文档的该部分内的水印进行相位改变，使得至少一个相移半色调图像包括相移区域和非相移区域。经修改的图像数据用于将文档的部分打印在经受UV照射时将发荧光的基底上。文档的打印部分包括由相移区域产生的第一印刷图案和由非相移区域产生的第二印刷图案。当文件的部分在可见光中观看时，文档的打印部分的第一和第二图案看起来基本相似，并且当在UV光中观看文档的部分时，显示不相似，使得编码在修改图像中的水印当文档的部分在紫外光下观看时，数据是可感知的，并且当在可见光中观看文档的部分时，数据被隐藏。

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.

摘要： A document printing method includes receiving a print job of electronic document data representing a document including a security character string with at least one character defined in the electronic document data in terms of a security mark creation font. The security mark creation font is a scalable outline based font, wherein the security character string is defined with a selected security effect, and wherein the security mark creation font provides an indication of the selected security effect without implementing the security effect. An SI Font is selected that corresponds to the security mark creation font of the at least one character of the security character string. The SI Font includes a bitmap representation of the at least one character of the security character string. The SI Font is suitable for printing the security character string with the selected security effect. The step of selecting an SI Font includes selecting the SI Font based upon a unique name of the SI Font that corresponds to a name of the security mark creation font, and also includes selecting the SI Font based upon at least one other attribute of the security mark creation font. A font substitution is performed in which the selected SI Font is used to define the security character string in the electronic document data in place of the security mark creation font. After the font substitution, a hard copy output of the document is printed as defined by the electronic document data including the substituted SI Font. A system is disclosed for performing the document printing method.

摘要： An improved technique for processing a color or gray scale pixel map representing a document is disclosed. The pixel map is decomposed into a three-plane representation, a reduced-resolution “upper” plane, a reduced-resolution “lower” plane, and a high-resolution binary selector plane. The “upper” and “lower” planes contain the color or gray scale for the page as well as the continuous tone pictures that are contained on the page. The selector plane stores information for selecting from either the foreground plane or background plane during decompression. Information contained in the selector plane is first used to pre-process the upper and lower planes to reduce the amount of data on each of the other two planes that will be subjected to further processing. Each of the pre-processed planes is compressed using a compression technique optimal for the type of data that resides upon it.

摘要： An image editing system and method provides a user with edit commands based on edit-related features for a raster image to be edited. The edit-related feature used to determine which edit commands are provided to the user can include DIR-type rendering hints, a compression ratio for the image or portion of the image, a compression scheme used to compress the image or portion of the image and other raster image features. The edit commands presented to a user can be user customized. Thus, an intelligent set of edit commands can be provided that is related to the raster image being edited.

摘要： A scanner generates a first set of M-bit signals representing an image in a document. A default table translates the M-bit signals into linearized N-bit signals where M>N. A color image processing module processes the N-bit signals to generate an image-dependent look-up table which, thereafter, is loaded into the scanner. The scanner then generates a second set of M-bit signals using a high resolution re-scan of the same image. The second set of M-bit signals are translated into N-bit signals using the image-dependent look-up table to generate an electronic representation with enhancement characteristics.

摘要： A method and apparatus for compressing a mixed raster content image that represents a color or gray scale a document is disclosed. The pixel map is decomposed into a three-plane representation—a reduced-resolution “upper” plane, a reduced-resolution “lower” plane, and a high-resolution binary selector plane. An iterative smoothing technique is then used to pre-process the upper and lower planes using the information contained in the selector plane, thereby reducing the amount of data that will be subjected to further processing.
