Retrieving system, retrieving method, and security inspection device based on contents of fluoroscopic images

摘要

Disclosed are a retrieving system and a retrieving method based on content of fluoroscopic images, the retrieving system (100) comprising: a pre-classifying module (101), configured to pre-classify fluoroscopic images; an image content feature extracting module (102), configured to perform feature extraction for contents of the fluoroscopic images; an image representing module (103), configured to construct an image representation vector; a retrieving module (104), configured to construct a result of preliminary candidates; a diversified filtering module (105), configured to filter the result of preliminary candidates, select an image subset capable of covering a plurality of article categories, and thereby construct a diversified retrieval result; a correlation feedback regulating module (106), configured to receive information feedback on the retrieval result from a user, and update the retrieval model; and an interacting module (107), configured to display the retrieval result, and collect feedback on user's satisfaction of the retrieval result.
