Abstract: PROBLEM TO BE SOLVED: To provide a data retrieval system, a data retrieval method, a program to make a computer execute data retrieval, a computer-readable storage medium which stores the program, and a graphical user interface to display a retrieved document. SOLUTION: The data retrieval system comprises: a database 12 to hold data as a digitalized vector based on a keyword; a means 24 which creates a residual vector from the data, calculates a covariance matrix and an eigenvector of the covariance matrix, creates a set of base vectors from a set of the calculated eigenvectors and lets it be stored; a means 22 which reads out the data and at least one of the eigenvectors from the memory, calculates a degree of contribution of the eigenvector to the data, and reduces or stretches the residual vector and lets it be stored; and a means 16 which selects a keyword to be used for labelling from a similarity of the stored base vector and the data, and a weight to the similarity, and lets it be stored in the memory.

Abstract: PROBLEM TO BE SOLVED: To provide a method for retrieving information from a large scale database (containing several millions of data) in real time, while controlling trade-off in precision of a retrieved result and a response time thereof to a user. SOLUTION: This method is applicable, for example, to the database including a content of a document modeled in a clearly defined distance capable of calculating a distance between any two points, wherein the pair of documents near in its distance is more similar than a pair of documents apart each other. The method is combined with similarity ranking and/or another method to enhance scalability in information retrieval, detection, raking and tracking. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To embed various information into a three-dimensional shape model and also to extract these embedded information. SOLUTION: This method changes the geometric parameters of a three- dimensional shape model to embed various information into the shape model in a visible or invisible state. The geometric parameters are equivalent to descriptions to define a geometric shape. The three-dimensional shape model usually consists of the polyhedrons, straight lines, a set of points or curved surfaces, i.e., its primitives (component elements), and each primitive is defined by a geometric parameter. Thereby, a three-dimensional shape model is defined by a set of many geometric parameters in regard to its entire geographic shape. The information is embedded in this system by changing the geometric parameters of plural primitives forming a three-dimensional shape model. Meanwhile, the geometric parameters are divided into numeric parameters and phases and varied for embedding the information. Then the varied geographic parameters are detected for extraction of the embedded information.

Abstract: PROBLEM TO BE SOLVED: To render a spot light with texture at a high speed. SOLUTION: At the time of rendering a three-dimensional space with the spot light source of a conical angle θ, the surface of an object within the three- dimensional space is meshed to be plural elements 310 at first. Then a radiosity from the spot light source is calculated with respect to each element included within the conical angle at the time of looking from the spot light source 320. After then, the luminance value of each vertex of each element is calculated from the radiosity calculated for each element 330. Then through the use of the luminance value of each vertex of each element, Gouraud shading is executed 380 to display the result on a display or the like.
