摘要： This invention generates a digital document by applying character recognition to character images in a document image, and rendering the character recognition result on the document image in a transparent color. This digital document allows to specify a part corresponding to a search keyword on the document image upon conducting a search. When this digital document is generated, it includes a description required to use glyph data (font data) of a simple character shape commonly to a plurality of character types as font data used upon rendering the character recognition result. Therefore, even when the digital document needs to save font data, an increase in file size can be minimized. Also, by rendering using a simple character shape, the data size of the font data itself can be reduced.
摘要翻译：本发明通过对文档图像中的字符图像应用字符识别并以文字图像将文字识别结果呈现为透明颜色来生成数字文档。该数字文档允许在进行搜索时在文档图像上指定与搜索关键词对应的部分。当生成该数字文档时，它包括将字符数据（字体数据）简单字符形状通常用作多个字符类型所需的描述，作为在呈现字符识别结果时使用的字体数据。因此，即使数字文档需要保存字体数据，文件大小也可以最小化。此外，通过使用简单的字符形状进行渲染，可以减少字体数据本身的数据大小。

摘要： A data processing apparatus produces electronic data from a document image in which a text part, a photograph part, etc. are mixed. This electronic data enables a user to display information in a required part. The apparatus extracts an object from an input image and integrates information on the extracted object and layout control information (script) for modifying a layout so as to generate integrated electronic data. A script program can be executed when the electronic data is used, which allows an object designated by a user to be magnified and rearranged so as to facilitate visualization of the object.

摘要： Forms such as business forms used in banks and post offices are automatically classified using a form search apparatus and method. The method of classifying forms comprises extracting features from the image data of the input form and comparing the extracted features with stored features of a set of template forms corresponding to a set of known classifications of forms. The comparing step compares extracted features which comprise attributes of tables contained in the template forms and the input form respectively. The attributes of tables may be the number of tables in the form, or the number of cells comprising the tables. An approximate matching step is used to reduce the number of candidate template forms.

摘要： An apparatus for embedding a digital watermark in a document image detects circumscribing outer shapes of characters in the document image and sets a plurality of reference lines that extend in the column direction and are spaced apart in the row direction by a basic pitch. The outer shapes include a first outer shape, a second outer shape that neighbors the first outer shape, and a third outer shape that neighbors the second outer shape, and the reference lines include a first reference line located between the first outer shape and the second outer shape, and a second reference line located between the second outer shape and the third outer shape. Control is performed for at least one of the second and third outer shapes so that a distance between the first reference line and an edge of the second outer shape is different from a distance between the second reference line and an edge of the third outer shape, in accordance with digital watermark information to be embedded.

摘要： There are provided an image processing apparatus and image processing method which can increase the processing efficiency upon obtaining data which allows re-use and re-editing of a document such as a paper document. While image data is input, and pieces of character information included in the input image data are sequentially recognized, the pieces of character information included in the input image data are subjected to outline conversion using vector data. At this time, the character type of the pieces of recognized character information and the vector data having undergone outline conversion are managed while being associated with each other. Upon recognizing the pieces of character information, it is determined whether the character type of the pieces of character information has undergone previous outline conversion. If it is determined that the character type has undergone the previous outline conversion, the management is controlled so as to use vector data used in the previous outline conversion.

摘要： A mobile terminal reads a read manuscript as image data. A character recognition block performs character recognition from the image data, which is read, on the basis of a threshold for judgement of unrecognizableness. A character recognition result is transmitted to a central control unit, or the threshold for judgement of unrecognizableness is received from the central control unit in a threshold receiver. On the other hand, the central control unit receives the result of character recognition from the mobile terminal, or transmits the threshold for judgement of unrecognizableness from a threshold transmitter to the mobile terminal. Furthermore, the central control unit controls the threshold for judgement of unrecognizableness with a threshold controller.
