摘要:
An apparatus receives a document image and digital-watermark information and determines an embedding capacity based on a number of the letters in the document image. The apparatus determines whether or not the entire digital-watermark information is capable of being embedded in the document image based on the determined embedding capacity and embeds the digital-watermark information in the document image based on a result of the determination of whether or not the entire digital-watermark information is capable of being embedded in the document image.

Distance d1 between the right edges of A1 and B2, and distance d2 between the right edges of A3 and B4 are calculated. If data to be embedded is 1, one or a combination of a process for increasing the size of B2 in the column direction or decreasing the size of B4 in the column and a process for moving the position of B2 toward B3 or moving the position of B4 toward B3 is executed to meet d1>d2. If data to be embedded is 0, one or a combination of a process for decreasing the size of B2 in the column direction or increasing the size of B4 in the column direction, and a process for moving the position of B2 toward B1 or moving the position of B4 toward B5 is executed to meet d1

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:
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.

摘要:
A document image undergoes document analysis to obtain circumscribing rectangles of characters (S601), and two distances between non-neighboring circumscribing rectangles from the head of the document are respectively calculated as d1 and d2 (S603). If information to be embedded is 1, one or a combination of a process for changing a parameter associated with the size of a circumscribing rectangle and a process for changing a parameter associated with the position of a circumscribing rectangle is executed to satisfy d1>d2 (S605). If information to be embedded is 0, one or a combination of the above two parameter change processes is executed to satisfy d1
摘要:
The invention generates moving image information obtained by compositing a moving image of a user and objects selected by the user, and provides the generated moving image information to the user. For instance, when the user has inserted a coin or coins into a device, a select menu of pre-stored stories is displayed, and the user selects one story from the menu. Then, the user selects a desired background scene and feature player in that story to determine pre-stored objects. After that, an image of the user is sensed, and is stored as a moving image object. The moving image object is then composited with the previously selected objects according to MPEG 4 to generate single stream information. The generated moving image information is then delivered to the user.
摘要:
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.
摘要:
The present invention provides a technique that allows for a valid modification that is authorized by the author of data, while assuring the originality of the data. An information processing apparatus for processing original data created by a predetermined author is provided. The information processing apparatus includes a modification-information storing unit for storing modification information regarding a modification onto a storage medium when the original data is modified, and a modification-assuring-information creating unit for creating modification assuring information for assuring that the modification information is true.
