Multi-media searching method and device

Abstract

The invention provides a multi-media searching method, comprising the following steps: a search condition sent by a client side is received, and the search condition comprises feature extraction algorithm ID and eigenvalue extracted by the feature extraction algorithm, corresponding to the feature extraction algorithm ID; a member multi-media search engine, corresponding to the feature extractionalgorithm ID, is chosen according to the feature extraction algorithm ID; the feature extraction algorithm ID and a search query of the eigenvalue are sent to the member multi-media search engine to search. A meta-search server is in charge of interoperability information maintenance of the feature extraction algorithm, a standardized feature extraction algorithm is avoided, support capacity of feature extraction algorithm of all member multi-media search engines is integrated by the meta-search server, so as to ensure the consistence of the feature extraction algorithm of the client side andthe member multi-media search engine.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and device for multimedia search. Background technique [0002] For content-based multimedia search, due to the diversity and continuous development of feature extraction algorithms, few feature extraction algorithms are currently accepted by the industry, so it is difficult to standardize the algorithms. For example, although MPEG-7 also standardized some feature extraction algorithms, but because its standardized feature extraction algorithms are not accepted by the industry, almost no search engines use the feature extraction algorithms specified by MPEG-7. [0003] The threshold of multimedia feature extraction algorithms is high, and there are not many manufacturers who have mastered efficient multimedia retrieval technologies. At the same time, the algorithms of multimedia retrieval technology providers are core technologies and will not be fully disclosed. Ho...

Problems solved by technology

[0004] For the multimedia search framework based on meta-search, it is necessary to send the search request containing the feature value sent by the client to multiple search engines. Since different search engines use different feature extraction algorithms, the search engine may not be able to understand the search request sent by the client. Meaning of eigenvalues
