    • An exemplary method for online character recognition of East Asian characters includes acquiring time sequential, online ink data for a handwritten East Asian character, conditioning the ink data to produce conditioned ink data where the conditioned ink data includes information as to writing sequence of the handwritten East Asian character and extracting features from the conditioned ink data where the features include a tangent feature, a curvature feature, a local length feature, a connection point feature and an imaginary stroke feature. Such a method may determine neighborhoods for ink data and extract features for each neighborhood. An exemplary Hidden Markov Model based character recognition system may use various exemplary methods for training and character recognition.
    • 用于东亚字符的在线字符识别的示例性方法包括获取用于手写东亚字符的时间顺序在线墨水数据,调节墨水数据以产生经调节的墨水数据,其中调节的墨水数据包括关于写入东方手写的顺序的信息 亚洲字符和从调节的墨水数据中提取特征,其中特征包括切线特征,曲率特征,局部长度特征,连接点特征和假想笔划特征。 这种方法可以确定墨水数据的邻域并提取每个邻域的特征。 基于示例性的基于隐马尔可夫模型的角色识别系统可以使用用于训练和角色识别的各种示例性方法。

    • Annotation engines are described for handling annotations added to a base document. The annotation engines automatically classify the type of annotations, including, but not limited to: a highlight annotation; a blob annotation (comprising an enclosing-type annotation); an underline annotation; a vertical bracket annotation; a call-out annotation; and a free-note annotation. The annotation engines accept input in the form of a hierarchical tree of document elements and generate an output in the form of a hierarchical tree of annotation elements. Among other uses, a reflow engine can use the output of the annotation engines to properly reposition annotations within a layout-modified base document.
    • 描述了注释引擎来处理添加到基本文档中的注释。 注释引擎自动对注释类型进行分类,包括但不限于:高亮注释; 一个blob注释(包含一个封闭类型的注释); 下划线注释; 垂直括号注释; 一个调用注释; 和一个免费注释注释。 注释引擎以文档元素的分层树的形式接受输入,并以注释元素的分层树的形式生成输出。 除了其他用途之外,回流引擎可以使用注释引擎的输出来在布局修改的基础文档中正确地重新定位注释。

    • At least one image captured from a printed document and at least one image captured from a display surface other than a printed document are processed. A surface-type-identification module accepts as input both types of images and identifies, for a particular image, the type of surface from which the image was captured. A display-surface-preprocessing module preprocesses the at least one embedded-interaction-code image captured from a display surface other than a printed document. A printed-document-preprocessing module preprocesses the at least one embedded-interaction-code images captured from a printed document. An embedded-interaction-code-processing module outputs location information for at least one of the at least one image captured from a printed document and the at least one image captured from a display surface other than a printed document.
    • 处理从打印文档捕获的至少一个图像和从打印文档以外的显示表面捕获的至少一个图像。 表面类型识别模块接受两种类型的图像作为输入,并且针对特定图像识别捕获图像的表面的类型。 显示表面预处理模块预处理从打印文档以外的显示表面捕获的至少一个嵌入式交互代码图像。 打印文档预处理模块预处理从打印文档捕获的至少一个嵌入式交互代码图像。 嵌入式交互代码处理模块输出从打印文档捕获的至少一个图像中的至少一个图像和从打印文档以外的显示表面捕获的至少一个图像的位置信息。
