Character code data and vector drawing data are both listed and provided in a re-editable manner. Electronic data is generated in which information obtained by vectorizing character areas in an image and information obtained by recognizing characters in the image are stored in respective storage locations. As for the electronic data generated in this manner, because character code data and vector drawing data generated from the input image are both presented by a display and edit program, a user can immediately utilize the both data.

Image processing device, method and storage medium for storing and displaying an electronic document

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.

Image processing apparatus, image processing method, and computer program

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.

Data processing apparatus, data processing method, and computer program for generating electronic data from a paper document

This invention provides the following environment. That is, an original document file corresponding to a document to be copied is specified from image data of that document to be copied, and a print process is made based on the specified file so as to prevent deterioration of image quality. Also, when a document to be copied is not registered, a registration process is executed to suppress deterioration of image quality in an early stage. Furthermore, since the document is converted into vector data, re-use of such document is facilitated, and deterioration of image quality can be suppressed even when an image process such as enlargement or the like is made. To this end, when an original digital file cannot be specified, an apparatus of this embodiment executes a vectorization process (S), converts the obtained vector data into a data format that can be re-used by an application (S), and registers the converted file in a file server (S). With this registration process, since the location of the file is settled, that location information is composited on an image to be scanned using an identifier such as a two-dimensional barcode or the like (S), and the composite image can be printed (S). Even when the printed document is scanned again, a registered digital file can be easily specified.

Image processing method, system, program, program storage medium and information processing apparatus

A method for image processing comprising inputting and reading a combined image that includes a latent image unperceivable by the human eye, a patterned image in the background allowing the latent image to appear clearly on a recording medium when data recorded on a recording medium is copied onto another recording medium, and text and/or image data embedded with a digital watermark. The text and/or image data is extracted from the combined image and the digital watermark extracted from the text and/or image data. A permission code enabling copying of image data composed of a combination of a patterned image and the extracted text and/or image data onto a recording medium is input. The copying is regulated based on the extracted digital watermark and the permission code.

Image processor, method thereof, computer program, and computer readable storage medium

Retrieval accuracy is improved by causing a difference in layout from document to document to be reflected in retrieval at will. To achieve this, there is provided an information processing method for a case having a plurality of retrieval steps (S, S, S) of retrieving image data that is similar to an input document image, the method including a step (S) of inputting weighting information for weighting a degree of similarity calculated by each of the retrieval steps; a step of weighting the degree of similarity, which has been calculated by each of the retrieval steps, for every item of image data on the basis of the weighting information, and calculating overall degree of similarity; and a step (S) of displaying the similar image data based upon the overall degree of similarity calculated.

Calculating image similarity using extracted data

It is required to protect the copyrights and the like of partial images which form respective parts of an image obtained by reading an image, exchanged using a print as a medium, by an image scanner or the like. Input image data is divided into a plurality of image regions having different features, digital watermarks, which are embedded in the detected image regions by embedding methods corresponding to the features of the image regions, are extracted, and the availability of the input image is checked on the basis of the extracted digital watermarks.

Image processing apparatus and method

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.

Form search apparatus and method

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.

Communication system and control method thereof, and computer-readable memory

A method for embedding a digital watermark includes a step of inputting digital watermark information; a step of inputting an image; a step of dividing the image into a plurality of areas; a step of ordering the plurality of areas according to a predetermined ordering criterion; a step of embedding the digital watermark information over the plurality of areas that have been ordered; and a step of outputting an image with the digital watermark information embedded therein.

Method, apparatus, and computer program product for embedding digital watermark, and method, apparatus, and computer program product for extracting digital watermark

Stored digital data is searched for on the basis of an input image, difference information is extracted by comparing the retrieved digital data and the input image, and the difference information is composited to the digital data. Digital data generated by composition is stored. When no digital data is retrieved, the input image is converted into vector data, and the image that has been converted into the vector data is stored as digital data. Obtained region segmentation information and an input image are composited, the composite image is displayed on an operation screen of an MFP, and a rectangular block to be vectorized is designated as a specific region from the displayed region segmentation information. A user designates the specific region by designating rectangular blocks in an image using a pointing device.

Image processing method

This invention provides an image processing method which allows easy re-use of image information that is stored to minimize deterioration of image quality and the storage capacity. Storage means is searched for original digital data corresponding to each input image. If no original digital data is found, the input image is converted into vector data, and is stored as digital data in the storage means. A sheet including at least one of information associated with the found original digital data when the original digital data is found in the search step and information associated with digital data which is obtained by converting the image into the vector data in the vectorization step and is stored in the storage step when no original digital data is found in the search step is generated, thus providing a sheet that allows easy re-use.

Image processing method and image processing system

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.
