摘要： A show-through reduction method is disclosed. The method is designed to deal with both light and severe show-through. The method focuses mostly on text documents, with characters possibly appearing in multiple gray levels, although the method can also be extended to color documents. As in the prior art, the front and back pages are processed in pairs. However, no perfect page alignment is assumed here, since we are dealing with real images. Instead, a front and back registration is performed as the first step before the pages are further analyzed. In this method, we are aligning the front page content with its show-through appearing in the back side, and the back page content with its show-through appearing in the front side. Once the two sides are aligned, masks are generated for both sides to differentiate severe show-through and light color content regions. Finally, different TRCs are applied to different regions. The show-through is reduced and the page contents are retained.
摘要翻译：公开了一种透视简化方法。该方法旨在处理轻型和重型展示。该方法主要集中在文本文档上，字符可能出现在多个灰度级，尽管该方法也可以扩展到彩色文档。如现有技术那样，前页和后页成对处理。然而，在这里假设没有完美的页面对齐，因为我们正在处理真实的图像。相反，在进一步分析页面之前，执行正面和背面注册作为第一步。在这种方法中，我们正在将首页内容与其后面的显示对齐，后端页面的内容与其显示出现在前面。一旦双方对齐，双方将产生掩模，以区分严重的透明和浅色内容区域。最后，不同的TRC应用于不同的地区。展示次数减少，页面内容保留。

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, and yet decipherable under infrared illumination when viewed by a suitable infrared sensitive device. This infrared mark entails in combination with at least one distraction pattern, a substrate reflective to infrared radiation, and a first colorant mixture and second colorant mixture printed as an image upon the substrate. The first 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 a second colorant mixture as printed in close spatial proximity to the first colorant mixture pattern, such that the resultant 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.
摘要翻译：本文提供的教导涉及嵌入在图像中的水印，其具有在正常光线下相对不可解译的性质，并且在由合适的红外敏感装置观看时在红外照明下可解码。该红外标记需要与至少一个分散图案，反射红外辐射的基底以及作为图像印刷在基底上的第一着色剂混合物和第二着色剂混合物组合。与基底相关的第一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第二着色剂混合物的低对比度的性质，其与第一着色剂混合物图案紧密相邻地印刷，使得适当地暴露于红外照明的所得到的图像渲染基板将产生作为适合的红外敏感装置的红外标记显而易见的可识别图像。

摘要： The tone reproduction curve is smoothed to eliminate or reduce artifacts due to abrupt changes in the final system tone reproduction curve. As the tone reproduction curve approaches an end point, it is modified, if necessary, so that the angle between a tangent to the tone reproduction curve at a point, and a line from that point to the end point is less than a threshold value. The end point is considered to be a corner of a box, the threshold value is a function of the distance from the point to the nearest of the walls of the corner, and the threshold value goes to zero as the distance to the wall goes to zero. Thus, the tone reproduction curve is guided to the end point in a smooth and monotonic fashion.

摘要： A color printer, responsive to printer signals to deposit printer colorants on a medium in accordance with printer signals received, is calibrated by operating the color printer with printer signals selected to cause the printer to print color samples on the medium; measuring the color samples to determine a first colorimetric response of the printer to the printer signals using the first measured colorimetric response to generate a first mapping of colorimetric values to printer signals; using the first measured colorimetric response or a subsequent measured colorimetric response to generate at least one additional mapping of colorimetric values to printer signals; storing the first and additional mappings in a color conversion memory producing printer signals as a function of the first and additional mappings stored in the color conversion memory to convert color definitions from a first color space to the printer signals suitable for producing a corresponding response at the color printer.

摘要： A method of calibrating the response of the printer to an image described in terms of colorimetric values, including the steps of: a) setting printer parameters; b) deriving a printer response characteristic by printing a calibration test from device dependent printer signals stored in a device memory, the calibration image including a plurality of color patches, some of which may be repeated at a plurality of locations on the test image at spatially disparate locations selected to keep local printer non-uniformities from affecting both locations; c) measuring printer response characteristics in device independent terms; d) generating a memory mapping of device independent colors to printer responses for subsequent use in printing images defined in device independent terms. The calibration target includes a large number of patches generated from combinations of printer colorants, and may repeat some of those patches either on the same sheet or on a plurality of sheets at positions on the sheet which are spatially distinct.

摘要： A fracturable manifold image is created in an imaging layer sandwiched between donor and receiver sheets by a conventional manifold imaging process using an imaging electrostatic field of a predetermined voltage. The fracturable manifold image is erased by uniformly applying in the dark a second electrostatic field of the same polarity as the first field but of sufficiently greater strength to cause substantially the entire imaging layer to preferentially adhere to one of the sheets. After the fracturable image has been created, but before erasure, the sandwich can be separated while still under the influence of the first field to provide a positive image on one sheet and a negative image on the other sheet and then reassembled substantially in registration. Subsequent such images can be made and erased provided that the imaging field for each subsequent image has at least the strength of the next previous erasure field.
