Embodiment 1

[0020] Embodiment 1: the retrieval system mainly includes three key technologies: feature extraction, content description and search engine, including: (1) content-based image retrieval CBIR; (2) multimedia content description interface MPEG-7; (3) database model and management;

[0021] Specifically, it includes: a feature extraction module, a retrieval module, an output module, and a query module.

[0022]Content-based image retrieval can be regarded as an information service system between users and image databases. When the user issues a query request, the system converts the query request into a description of the data content by analyzing and extracting features from the query data, searches with the help of these descriptions, and extracts the required information by matching with the information in the database. information data.

[0023] MPEG-7 is about content description, its connection with content-based image retrieval can be found in figure 1 . The dotted box...

Abstract

The invention discloses an MPEG-7-based image retrieving system, which mainly comprises three key techniques, namely, characteristic extraction, content description and searching engine. The MPEG-7-based image retrieving system comprises (1) content-based image retrieval CBIR, (2) a multimedia content description interface MPEG-7 and (3) a database model and management. Specifically, the MPEG-7-based image retrieving system comprises a characteristic extraction module, a retrieval module, an output module and a query module, and realizes network function-oriented image content-based query, so that a user can quickly and effectively retrieve image resources. A descriptor specified by an MPEG-7 standard is improved so as to obtain remarkable retrieval effect and perform combined query on different visual characteristics, such as colors, textures and shapes. The image retrieving system is developed for digital libraries, medical application and trademark retrieval application, and an algorithm is optimized according to the MPEG-7 standard, so that the MPEG-7-based image retrieving system reaches a leading domestic level in terms of algorithm study and application. The MPEG-7-based image retrieving system has the characteristics of clear technical direction, smooth development and relatively stronger maturity.

Description

technical field [0001] The invention uses color, texture and shape visual descriptors to describe image content information, and enables users to quickly and effectively retrieve image resources, especially an image retrieval system based on MPEG-7. Background technique [0002] With the rapid rise of my country's content culture industry based on digital technology and the rapid increase in the amount of video and audio information, TV and film archives need to save more and more video and audio materials, and a large number of video and audio materials are generated every day information; with the development of my country's e-government and public information digitization, agencies and institutions at all levels will generate a large amount of multimedia information; as more and more digital medical equipment is put into use in hospitals and health departments at all levels in our country, a large number of diagnostic Information is reflected in the form of images. It beco...
