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： A method and system for creating guilloché base pattern with two-dimensional periodicity in a plurality of replicate patterns is shown wherein the creating can be assessed in real-time for pattern acceptability by a user. A base pattern is set on an imaging device in vector space relative to a set of predetermined pattern nodes. The base pattern is modulated via a user interface by adjusting positions of the pattern known for selectively controlling curve shapes of the pattern. A guilloché mark is illustrated by display on the imaging device of the adjusted base pattern and a compilation of associated replicate patterns for user assessment of the mark.

摘要： A method and system is provided providing a variable data guilloché pattern comprised of variable data differential line pattern fonts comprising decodable template symbols which are capable of being selectively assembled into a predetermined variable data code. The differential line pattern fonts are further spatially modulated for imposition of a second data channel on a printed document. The representation can be decoded with a digital scanner capable of identifying the embedded patterns and spatially modulated transform function and communicate it to a user for verifying a document containing the code.
