摘要

在屏幕小的设备上查看多页高分辨率文档是很困难的。作为一种解决方案,我们引入了一个多媒体缩略图表示,它可以被看作是一个多媒体剪辑,它提供了通过文档的自动导览。多媒体缩略图是通过将文档图像作为输入并首先对文档执行视觉和听觉信息分析以确定突出的文档元素来自动生成的。接下来,通过考虑显示和应用程序约束来计算每个文档元素的时间和信息属性。在给定时间限制的情况下,优化例程选择要包含在多媒体缩略图中的元素。最后,将选定的元素合成为动画图像和音频,以创建最终的多媒体表示

Computing a Multimedia Representation for Documents Given Time and Display Constraints
It is difficult to view multipage, high resolution documents on devices with small displays. As a solution, we introduce a multimedia thumbnail representation, which can be seen as a multimedia clip that provides an automated guided tour through a document. Multimedia thumbnails are automatically generated by taking a document image as input and first performing visual and audible information analysis on the document to determine salient document elements. Next, the time and information attributes for each document element are computed by taking into account the display and application constraints. An optimization routine, given a time constraint, selects elements to be included in the multimedia thumbnail. Last, the selected elements are synthesized into animated images and audio to create the final multimedia representation
