Provides ability to analyze the readability of an image to be displayed on a screen as a web page, etc., and appropriately modify the image. It includes a rendering section for generating an image by rendering an HTML document; an image processing section for performing image processing on the image generated by the rendering section to simulate and evaluate how the image is viewed under a certain visual characteristic; and a result presentation section for locating an HTML element that needs to be modified in the HTML document to be processed based on the evaluation result of the image processing section and for presenting the HTML element to a web page creator. The result presentation section also retrieves a modification method for the HTML element that needs to be modified from a symptom model storage section. A document modification processing section actually modifies the HTML document.

Digest screen display content deciding means selects display elements belonging to respective regions of a document based on display priorities of the display elements, which are obtained by digest screen display priority information creating means, and decides selected display elements as display content of a digest screen under a condition where a total display area does not exceed a required display area. A merging relationship among the regions is set based on layout information for the regions, created by digest screen region layout information creating means. Display content deciding means decides the display content of a detail screen based on the merging relationship among the regions, and creates a digest of the detail screen based on control information created by control information creating means. Moreover, digest screen display content changing means changes the display content of the digest screen in response to an operation of a user.

Information processing for creating a document digest

A head detecting apparatus, including a foreground extraction section for extracting a foreground region in which a person is captured from an input image; a first main axis computing section which includes a first moment computing section for computing a moment around a center of gravity of the foreground region and calculating a main axis of the foreground region based on the moment around the center of gravity of the foreground region; a head computing section for computing a head region included in the foreground region as a part thereof based on the main axis of the foreground region and a shape of the foreground region; and an ellipse determining section for determining an ellipse to be applied to a person's head based on a shape of the head region.

A method for extracting invisible information from an object in which visible information overlaps with at least part of invisible information formed in stealth ink. The method includes the steps of: irradiating the object with light for making the stealth ink luminous; receiving reflected light from the object; extracting image information from the received reflected light; splitting the image information into a plurality of pieces of color-channel information; obtaining a correlation function between the pixel values of at least two color-channel information selected from the plurality of pieces of color-channel information; reducing a visible information component of selected one of the plurality of pieces of color-channel information to thereby interpolate the color-channel information; and extracting invisible information from the interpolated one piece of color-channel information.

System, method, and program for extracting invisible information

Provides evaluating programs that enable problems to be identified in a manner that reflects actual conditions for an evaluation of contents of interest. In an example embodiment, there is provided a program for evaluating contents of interest that causes a computer to implement the functions of: performing a primary evaluation of contents of interest on the basis of one evaluation criterion; performing a primary evaluation of the contents of interest on the basis of another evaluation criterion; and performing a secondary evaluation of the contents of interest on the basis of a plurality of the first evaluations.

Computer evaluation of contents of interest

The present invention provides improvement of operations providing annotation and layout for an HTML page file. In an example embodiment, a page acquisition module obtains page files from a web server, and an HTML file analysis module extracts tags and characteristic values related to the layout. A page group detection module employs layout tags and their characteristic values to group page files that have the same or a similar layout. When an annotation addition module adds an annotation to an arbitrary page file in the obtained layout group, the annotation is applied for another page file in the layout group. When the layout group is divided or layout groups are unified, a correction module for the function of distance calculation corrects a calculation expression for a distance between pages or layout groups in order to reflect the division or unification results obtained by the user.

Display annotation and layout processing

An object of the present invention is to provide a description method for efficiently representing contents of motion picture with a small data volume. The organization of the present invention (1) represents a trajectory of how each object has moved over time by using reference plane representing position information of each object, (2) sets a description unit based on a type of action of each object by using changes in shape of each object, (3) has actions of each object represented as each behavioral section, and (4) comprises a description facility capable of reading and interpreting definition of an object dependent on video contents, definition of classes of actions, and definition of interpretation of a scene by interaction of plural objects.

Method and device for describing video contents

The present invention provides a means to display the contents of a document using a selected display condition, while preserving the layout of the document. It provides an information processing system comprising: a web browser for displaying a document having a predetermined layout; and a display controller for controlling a method used by the web browser to display the document. The display controller includes: a layout structure analyzer for analyzing the structure of the layout for the document; a region arrangement determiner for dividing a web page under a desired display condition, whereby the contents of the page are displayed in order to display the document in accordance with regions that are allocated and that reflect the structure of the document layout obtained by the layout structure analyzer; and an intra-region contents determiner for determining which contents of the document are to be displayed inside each of the allocated regions that are determined by the region arrangement determiner.

The invention provides a method for classifying the motion of an object such as a human being in a moving picture. A template is prepared in advance, which includes the Gabor wavelet expansion coefficients of an object image in a plurality of frames of a video image sequence representing each of a plurality of different reference motions of an object in a moving picture. Then, processing is performed to obtain the Gabor wavelet expansion coefficients of an object image in a plurality of frames of a video image sequence representing an unknown motion of the object. Matching factors are calculated based on the expansion coefficients for the unknown motion and the expansion coefficients for the reference motions in the template, and finally the unknown motion is classified based on the matching factors.

A method for embedding additional information into a video movie without substantially having an influence on the compression efficiency of the video movie and also without substantially causing degradation of the picture quality. Particularly, the method of the present invention involves specifying at least one embedding region in the frame of the video movie for embedding information, and determining a type of interframe prediction of the embedding region in correspondence with information to be embedded by referring to an embedding rule where a content of data to be embedded is caused to correspond to the type of interframe prediction of the embedding region. It is desirable that the frame in which the embedding region exists is a bidirectionally predictive-coded frame.
