Patent number: 7219089Abstract: A data retrieval system having a database storing data as a vector that has been digitized based on a keyword. The system has capability of generating a residual vector from the data to compute a covariance matrix and an eigenvector of the covariance matrix. The system further has the capability for generating and storing a set of basic vectors from the set of the computed eigenvectors, and for reading out the data and at least one of the eigenvectors from a memory. This is utilized to compute a contribution of the eigenvector to the data, and for contracting or enlarging a residual vector to store. The system selects a keyword to be used for labeling according to a similarity between the stored basic vector and the data, and a weight on the similarity so as to store the keyword in a memory.Type: GrantFiled: September 24, 2003Date of Patent: May 15, 2007Assignee: International Business Machines CorporationInventors: Mei Kobayashi, Masaki Aono

Patent number: 7216129Abstract: A method is provided for retrieving information from massive databases (i.e., databases with millions of documents) in real time, that allows users to control the trade-off between accuracy in retrieved results and response times. The method may be applied to databases with contents, i.e., documents which have been modeled with a clearly defined metric that enables computation of distances between any two documents, so that pairs of documents which are “closer” with respect to the metric are more similar than pairs of documents which are “further apart”. Our method can be applied to similarity ranking and/or can be combined together with other methods to increase the scalability of information retrieval, detection, ranking, and tracking.Type: GrantFiled: February 19, 2003Date of Patent: May 8, 2007Assignee: International Business Machines CorporationInventors: Masaki Aono, Michael Edward Houle, Mei Kobayashi

Patent number: 6314205Abstract: A data compression method for processing topological structures of various geometric models. A topological transformation is performed for a three-dimensional (3D) geometric model that is to be compressed, and a triangle mesh is generated. A conventional triangle mesh compression method is employed. Associated data required for the performance of a reverse operation for the topological transformation are prepared. As a result, topological data for the 3D geometric model is compressed. As needed, the data for the compressed triangle mesh and associated operation data are output. Furthermore, a necessary process (e.g., a compression process) is also performed for geometric data for the 3D geometric model, and the resultant data are either stored or output. For the decompression of compressed data, the compressed triangle mesh is decompressed using the method employed for compression, and a triangle mesh is generated.Type: GrantFiled: July 21, 1998Date of Patent: November 6, 2001Assignee: International Business Machines CorporationInventors: Hiroshi Masuda, Masaki Aono, Ryutarou Ohbuchi

Patent number: 6201881Abstract: Information is embedded in a three-dimensional geometric model in a visible or invisible state by changing geometric parameters of a three-dimensional geometric model. The three-dimensional geometric model comprises polyhedrons, lines, a set of points, or curved surfaces which are primitives (components) of the model. Each primitive is defined by a geometric parameter. The geometric shape of a three-dimensional geometric model is defined by a set of many geometric parameters. The information is embedded by changing the geometric parameters of a plurality of primitives constituting a three-dimensional geometric model.Type: GrantFiled: May 22, 1998Date of Patent: March 13, 2001Assignee: International Business Machines CorporationInventors: Hiroshi Masuda, Ryutarou Ohbuchi, Masaki Aono
