Multimedia target information visual analysis system

Abstract

The invention discloses a multimedia target information visual analysis system. A multimedia target information acquisition module acquires multimedia data, and stores the acquired multimedia data in a local database; a data preprocessing module performs semantic synthesis on the multimedia target information with a media-cross information integration technology; a multimedia target information retrieval module retrieves target information concerned by a user to form a multimedia file set; a visual graphical interface module performs visual output on the multimedia file set with a computer information visualization algorithm; and a target information interactive analysis module controls the extraction of data and the display of a picture through an interactive means, and performs intelligent screening and anomaly analysis of the multimedia target information in combination with statistics, clustering and linear regression analysis methods in order to ascertain the value of an analysis object. The multimedia target information visual analysis system has universality in multi-information display and a high flexibility degree in information primitive presentation, and can be used for providing feedback support to aid decision making.

Description

technical field [0001] The invention relates to target information analysis, which is used for computer aided intelligence analysis and decision support, in particular to a multimedia target information visualization analysis system. Background technique [0002] With the wide application of computer digital technology, the channels for people to obtain information are increasingly broadened. Information retrieval for any target of interest may result in massive amounts of data including text, images, video and audio. With the development of computer graphics and graphics technology, relying on the huge processing power of computers, various types of data can be converted into static or dynamic images and graphics presented in front of people through information computing and visualization technology, which can help people analyze and understand data, form concepts and Finding patterns provides a powerful tool. How to extract the information that can best reflect the needs ...
