This invention discloses an image retrieval apparatus. The image retrieval apparatus comprises an unlabelled image selector for selecting one or more unlabelled image(s) from an image database; and a main learner for training in each feedback round of the image retrieval, estimating relevance of images in the image database and a user's intention, and determining retrieval results, wherein the main learner makes use of the unlabelled image(s) selected by the unlabelled image selector in the estimation. In addition, the image retrieval apparatus may also include an active selector for selecting, in each feedback round and according to estimation results of the main learner, one or more unlabelled image(s) from the image database for the user to label.

Image retrieval apparatus

An image retrieval method includes reading from a first database a first image group mapped to an object as a retrieval target, and extracting an image feature quantity of a plurality of images of the first image group. A second image group mapped to an object as a search key is read from a second database and an image feature quantity of a plurality of images of the second image group is extracted. Similarity is determined between the first image group and the second image group, based on the image feature quantity of the plurality of images of the first image group and the image feature quantity of the plurality of images of the second image group. On an output device, as retrieval results, the plurality of images of the first image group are displayed in order of similarity of the object as the retrieval target based on determined similarity.

A computer readable recording medium stores an information attachment program for attaching meta-information to multimedia data executed by a computer. The program causes the computer to perform an acquisition step of acquiring a search word of a text search done at a search site; a monitoring step of monitoring whether or not a search frequency of the search word acquired in the acquisition step satisfies a predetermined criterion; a determination step of determining whether or not at least a portion of the search word matches a character recognition processing result of the multimedia data when the search frequency of the search word is determined to satisfy the predetermined criterion in the monitoring step; and a registration step of registering the search word as meta-information of the multimedia data when, as a determination result of the determination step, the search word matches the character recognition processing result.

A difference emphasizing apparatus aligns a first three-dimensional model and a second three-dimensional model in orientation and position in accordance with a predetermined rule, and gets data of respective apices of the first three-dimensional model and the second three-dimensional model. Based on the gotten data, the apparatus finds a corresponding point on the first three-dimensional model, which corresponds to the apex of the second three-dimensional model in a direction of a particular axis. When the corresponding point is detected, the apparatus calculates a difference between the first three-dimensional model and the second three-dimensional model in the direction of the particular axis based on the corresponding point and the apex of the second three-dimensional model. The apparatus enlarges the difference in the direction of the particular axis, and calculates a position of the apex of the second three-dimensional model after the enlargement.

A rule discovery program which enables discovery of a rule by automatically searching for a feature portion which is effective for generation of a rule in multimedia data. When sample data items are inputted, a search unit selects evaluation positions on a data array constituting each of the sample data items so as to generate a selection pattern. Next, an integration unit integrates the evaluation positions in the selection pattern so as to generate a predetermined number of evaluation regions, and a rule-candidate generation unit generates a rule candidate indicating a relationship common to the sample data items. A rule-candidate evaluation unit evaluates the generated rule candidate, and an output unit outputs, as a rule, the rule candidate when the rule candidate satisfies a predetermined criterion.

A television personal computer, when saving video databy recording a video content, extracts a section containing a predetermined type of scene from within the video content, and displays, when instructed to reproduce the video data, a picture framing area and a time line. The time line includes blocks specifying the section containing the predetermined type of scene together with this type of scene, and an indicator indicating a reproducing point is displayed on the time line.

The present invention relates to three-dimensional model retrieval apparatus and method. The three-dimensional model retrieval apparatus according to the present invention comprises a model normalizing unit for rotating and/or translating a three-dimensional model so that main axis directions of the three-dimensional model are consistent with coordinate axes of a system coordinate system, and barycenter of the three-dimensional model is consistent with origin of the system coordinate system; a two-dimensional image generating unit for projecting said three-dimensional model respectively in a positive direction and a negative direction of each coordinate axis of said system coordinate system to generate a plurality of two-dimensional images; a model describing unit for generating a model descriptor of the three-dimensional model from said two-dimensional images; and a retrieving unit for retrieving, based on said model descriptor, a three-dimensional model which most matches an input query from a model database.

A design support apparatus extracts feature data corresponding to design data to be searched upon receiving the design data to be searched. The apparatus checks the extracted feature data against the feature data associated with the feature associated information, ordering the design data associated with the feature associated information in descending order of similarity to the design data to be searched, retrieving one piece of the ordered design data. The apparatus generates a classification hierarchy consisting of pieces of classification data obtained by classifying a set of the retrieved design data based on a degree of feature similarity using the feature data associated with the feature associated information. The apparatus selects the design information closely associated with the classification data by fetching the design information corresponding to the design data contained in the classification data from the design associated information associating the design data and the design information.
