Abstract

The invention discloses an image retrieval method based on semantic mapping space construction. The image retrieval method is characterized by comprising the steps of (1) learning semantic mapping space, (2) estimating a semantic concept of each image which is not labeled, (3) conducting ascending sorting on the images corresponding to the semantic concepts in the semantic space, (4) inputting text search terms to be retrieved, and returning the images corresponding to the semantic concepts. According to the image retrieval method, the image retrieval accuracy can be effectively improved.

Description

technical field

[0001] The invention belongs to the technical field of information retrieval, and mainly relates to an image retrieval method based on semantic mapping space construction. Background technique

[0002] The 21st century is the information age, with the further popularization and rapid development of computer and network technology, the multimedia data represented by images on the Internet is growing explosively. Therefore, image retrieval technology has received more and more attention from researchers in different fields. Researchers aim to provide users with better image browsing and retrieval services to improve user satisfaction in image retrieval.

[0003] The mainstream image retrieval methods can be divided into two categories: text-based image retrieval and content-based image retrieval.

[0004] Text-based image retrieval methods usually use text information to describe image content, and use short annotations or text labels to index images in databa...
