Abstract: A image processing apparatus extracts a plurality of feature points, comprising a local feature amount, from an inputted image, and a region information that relates to the feature point, identifies at least one of the plurality of feature points, associates the feature point thus identified with a feature point with a high relational degree between the feature point thus identified and a region that is denoted by the region information of the feature point thus identified, and registers the feature point thus identified and associated as an index of the inputted image.

Abstract: When retrieving an image from an archive of stored images that is similar to an inputted image, an image-processing apparatus (200) extracts more than one characteristic point from the inputted image (S504), computes a characteristic amount for the characteristic points thus extracted (S505), and evaluates the fluctuation in the characteristic amount when a prescribed alteration is applied to the inputted image (S506). The image-processing apparatus selects a characteristic point from among the characteristic points thus extracted from the inputted image, and retrieves (S508) a stored image that is similar to the inputted image, in accordance with the characteristic amount of the characteristic point thus selected.

Abstract: A plurality of feature points are extracted from an inputted image, and a feature amount is computed with regard to the feature point thus extracted. A prescribed plurality of alterations, i.e., a rotation, an enlargement, or a reduction, are applied to the inputted image, a plurality of altered feature amounts are estimated with regard to the feature point, and an image is retrieved from among stored images that are stored upon a storage apparatus and that is most similar to the inputted image, in accordance with the plurality of the estimated altered feature amounts.

Abstract: A search request input processing unit holds an input query word in a query word holding unit. An associative word unfolding processing unit acquires associative words in association with the query word held in the query word holding unit with reference to an associative word dictionary. An image content search processing unit using associative words makes a keyword search of image information on the basis of the obtained associative words and the query word. A sensory pattern unfolding processing unit obtains the query word and sensory patterns corresponding to associative words of the query word, and searches image information using feature amounts of the obtained sensory patterns. A search result integration processing unit integrates the search results obtained by the image content word search processing unit and sensory pattern search processing unit.

Abstract: An information input apparatus for inputting content information and obtaining attribute information for identifying the content information. By transmitting the obtained attribute information to other apparatuses when the content information is input, attribute information can be easily added to the content information. Then, the attribute information added to the content information can be distributed.

Abstract: Metadata corresponding to each segment is added to a content. Each metadata describes a metadata item such as the dominant color or person of the segment. Each metadata item describes metametadata for representing an editing content to the content that influences the effectiveness of the metadata item. When the content is edited, an information processing apparatus adds to the metametadata a description representing executed editing. From the metametadata, the information processing apparatus which processes the content can determine the effectiveness of each metadata item. As a result, the effectiveness of each metadata can be reliably determined.

Abstract: An information processing method according to the present invention for editing multimedia content including metadata includes a receiving step and a determining step. In the receiving step, operation information about an editing operation is received. In the determining step, it is determined whether or not the metadata is usable for the edited multimedia content in accordance with the operation information and a property of the metadata in which a change in the reliability of the metadata due to the editing operation is written.

Abstract: A search request input processing unit holds an input query word in a query word holding unit. An associative word unfolding processing unit acquires associative words in association with the query word held in the query word holding unit with reference to an associative word dictionary. An image content search processing unit using associative words makes a keyword search of image information on the basis of the obtained associative words and the query word. A sensory pattern unfolding processing unit obtains the query word and sensory patterns corresponding to associative words of the query word, and searches image information using feature amounts of the obtained sensory patterns. A search result integration processing unit integrates the search results obtained by the image content word search processing unit and sensory pattern search processing unit.

Abstract: According to this invention, upon managing a plurality of data by individually appending meta data used to search for the data, an input sheet that describes predetermined candidates of meta data is prepared, the user selects meta data from the candidates of meta data, and the selected meta data is saved in association with the data. Upon making a search, a data search is conducted using meta data, and after the data found by search are partially provided to the user, the user selects desired data. In this way, everyone can easily and efficiently append information for a search to data to be managed.
