    • Systems and methods for generating graphical bar codes (i.e., images that contain inconspicuous graphical modulations that encode embedded information) by halftoning with embedded graphical encoding are described. In one aspect, a graphical bar code is generated by halftoning regions of an original image. The original image regions incorporate errors diffused among regions of the original image and computed based at least in part upon modulations in the graphical bar code corresponding to a graphical encoding of a message. In another aspect, a graphical bar code is decoded by generating a base image having halftone regions representative of an original image. Regions of the base image are compared probabilistically to a set of graphical code words to obtain a sequence of graphical code words corresponding to a graphical encoding of a message. The sequence of graphical code words is decoded to produce a decoded message.
    • 描述了通过利用嵌入式图形编码进行半色调来生成图形条形码(即,包含编码嵌入信息的不显眼图形调制的图像)的系统和方法。 在一个方面,通过对原始图像的区域进行半色调生成图形条形码。 原始图像区域包括在原始图像的区域之间扩散的错误,并且至少部分地基于对应于消息的图形编码的图形条形码的调制来计算。 在另一方面,通过产生具有表示原始图像的半色调区域的基本图像来对图形条形码进行解码。 将基本图像的区域概率地与一组图形代码字进行比较,以获得与消息的图形编码相对应的图形代码字的序列。 图形代码字的序列被解码以产生解码的消息。

    • Embodiments of the present invention are directed to automated methods and systems for generating mixed-content documents. In one embodiment, an automated method for generating a document layout includes receiving raw text, figures, references, and semantic information as input (901), and determining an allocation (1003) of text, figures, and references for each page of a document. The method also includes, for each page of the document, determining a template (1005) for displaying the allocation assigned to the page, and scaling template fields to exhibit the text, figures, and references assigned to the page. The method then renders (1007) the document with text, figures, and references allocated to each page within appropriate scaled template fields of the template selected for each page.

    • A method for tone mapping a digital image comprised of a plurality of high bit depth intensity values in linear space is disclosed. First, a plurality of liner intensity values are mapped from the linear space to a non-linear space (402). Then a left and a right boundary interval value are determined in the linear space for each of the plurality of high bit depth intensity value (404). A dither pattern is then overlaid onto the plurality of high bit depth intensity values in linear space (406). For each one of the plurality of high bit depth intensity values in linear space, one of the boundary interval values is selected, based on the current high bit depth intensity value, the left and right boundary interval values for the current pixel, and the dither pattern value overlaid onto the current pixel (408). Each of the selected boundary interval values are mapped into a lower bit depth non-linear space (410). And then the mapped selected boundary interval values are stored onto a computer readable medium.
