摘要： A watermark can be embedded in an image that has the property of being relatively indecipherable under normal light by including a distraction pattern, and yet remains decipherable under infrared illumination when viewed by a suitable infrared sensitive instrument. This infrared mark comprises, a substrate reflective to infrared radiation, a foreground colorant mixture printed as an image upon the substrate, a background colorant mixture and a distraction colorant mixture. A resultant collocated image rendered substrate suitably exposed to an infrared illumination, will yield a discernable image evident as a infrared mark to a suitable infrared sensitive device, but remain undecipherable under normal ambient light.

摘要： The teachings as provided herein relate to a watermark embedded in an image that has the property of being relatively indecipherable under normal light by including a distraction pattern, and yet remains decipherable under infrared illumination when viewed by a suitable infrared sensitive instrument. This infrared mark comprises, a substrate reflective to infrared radiation, a foreground colorant mixture printed as an image upon the substrate, a background colorant mixture and a distraction colorant mixture. The foreground colorant mixture layer in connection with the substrate has a property of strongly reflecting infrared illumination, as well as a property of low contrast under normal illumination against the background colorant mixture as printed in close spatial proximity to the foreground colorant mixture pattern. A distraction colorant mixture is selected to have a substantially negligent effect on the infrared response of the foreground and background color mixtures, but as having a substantially noticeable effect of the visual response of the foreground and background color mixtures when provided as a distraction pattern, such that a resultant collocated image rendered substrate suitably exposed to an infrared illumination, will yield a discernable image evident as a infrared mark to a suitable infrared sensitive device, but remain undecipherable under normal ambient light.
摘要翻译：本文提供的教导涉及嵌入图像中的水印，其具有通过包括分散图案在正常光线下相对不可解译的性质，并且当由合适的红外敏感仪器观看时仍然在红外照明下保持可解密。该红外标记包括反射红外辐射的基底，在基底上印刷为图像的前景着色剂混合物，背景着色剂混合物和牵引着色剂混合物。与衬底相关的前景着色剂混合物层具有强烈反射红外照明的性质，以及在正常照射下对背景着色剂混合物的低对比度的性质，其印刷在与前景着色剂混合物图案紧密相邻的空间附近。选择分散着色剂混合物对前景和背景颜色混合物的红外响应具有实质上的疏忽效应，但是当作为分散模式提供时具有对前景和背景颜色混合物的视觉响应的基本上显着的影响，例如使得适当地暴露于红外照明的所得并置图像渲染的衬底将产生可见的图像作为适合的红外敏感装置的红外标记，但在正常环境光下保持不可破译。

摘要： A variable data pantograph is formed by receiving a variable data string and retrieving at least one character representation from a vocabulary of character representations stored in memory. The retrieved at least one character representation corresponds to the variable data string. Each of the character representations in the vocabulary is associated with a foreground region including a character shape and a background region suitably sized and arranged for encompassing the foreground region. The background region incorporates a first pattern of elements and is controlled to render a target color using a first set of color separation control data and the foreground region incorporates a second pattern of elements and is controlled to render the target color using a second set of color separation control data. The retrieved at least one character representation is assembled to form a variable data pantograph, whereby when the variable data pantograph is rendered in an original document, the foreground and background regions are similar in tone, the foreground and background regions being substantially less similar in tone in a copy of the original document to render the character visible.

摘要： Systems and methods are described that facilitate identifying objects in a document (e.g., a PDF document) for automatic image enhancement (AIE). A PDF document is “chunked” or segmented into chunks, and boundaries between chunks are identified as real or imaginary. Chunks sharing imaginary boundaries are combined, while real boundaries are retained, to generate “de-chunked” objects. These objects are then classified, and an AIE application is executed on objects meeting pre-specified classification criteria. In this manner, objects of r which AIE is not desired are not subjected to the AIE application, thereby saving time and processing resources associated with enhancing the document.
摘要翻译：描述了便于识别用于自动图像增强（AIE）的文档中的对象（例如，PDF文档）的系统和方法。 PDF文档被“分块”或分割成块，并且块之间的边界被识别为实际或虚构。组合共享虚拟边界的块，而保留实际边界，以生成“去分块”对象。然后对这些对象进行分类，并在符合预先指定的分类标准的对象上执行AIE应用程序。以这种方式，不需要AIE的对象不进行AIE应用，从而节省与增强文档相关联的时间和处理资源。

摘要： As set forth herein, a computer-implemented method facilitates replacing text on cylindrical or curved surfaces in images. For instance, the user is first asked to perform a multi-click selection of a polygon to bound the text. A triangulation scheme is carried out to identify the pixels. Segmentation and erasing algorithms are then applied. The ellipses are estimated accurately through constrained least squares fitting. A 3D framework for rendering the text, including the central projection pinhole camera model and specification of the cylindrical object, is generated. These parameters are jointly estimated from the fitted ellipses as well as the two vertical edges of the cylinder. The personalized text is wrapped around the cylinder and subsequently rendered.
摘要翻译：如本文所述，计算机实现的方法有助于在图像中的圆柱形或弯曲表面上替换文本。例如，首先要求用户执行多边形的多点选择以绑定文本。进行三角测量方案来识别像素。然后应用分割和擦除算法。通过约束最小二乘拟合精确估计椭圆。生成用于呈现文本的3D框架，包括中心投影针孔相机模型和圆柱形对象的规格。这些参数是从安装的椭圆以及气缸的两个垂直边缘共同估计的。个性化文字包裹在圆柱体上并随后呈现。

摘要： A method and system convert an original digital image being represented by a first color space to a digital image being represented by a second color space by transforming the original image data represented by a first color space to second image data being represented by a second color space, the transformation causing the colors of the transformed image data to be substantially encodable in the second color space. The second image data represented by the second color space is transformed to third image data represented by the first color space, the transformation causing the colors of the transformed image data to be substantially encodable in the first color space. Distortions in the third image data represented by the first color space are corrected to form corrected image data represented by the first color space, and the corrected image data represented by the first color space is transformed to fourth image data represented by the second color space.

摘要： Identifying the substrate type of a target substrate before patterning by a marking engine produces an opportunity to adjust the marking engine. The adjustments can enable the marking engine to produce higher quality work. The target substrate's substrate type can be automatically identified by obtaining its characteristics and submitting them to a classifier. A spectrophotometer can measure a substrates reflectance spectrum, which is a good characteristic for use in classifying. Classifiers can be based on known distance or correlation measures.

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： An image characterized by an original image gamut is received in an imaging device characterized by a device gamut. The original image gamut is enhanced to a first set of modified color values that occupy a greater fraction of the device gamut than the original image gamut. The modified color values of each pixel are mapped to new color values within the device gamut.
