Abstract

The invention discloses an image retrieval method and an image retrieval system. The method includes for given query texts and/or query images, acquiring multiple similarity ordered lists of in-base images according to text relevance and image content relevance, and then returning a comprehensive ordered list by combining the acquired ordered lists and comprehensively considering the text similarity and the image content similarity. Through the multi-mode mixed retrieval mechanism, shortcomings of conventional single-mode retrieval mechanisms are overcome, respective advantages of a text retrieval method and an image content retrieval method are developed, and accuracy of image retrieval is greatly improved. Since only ordering results of single retrieval models are fused, the single retrieval models can be increased, decreased and replaced conveniently, text and image content feature retrieval models are configured flexibly, and performance of the image retrieval system is improved.

Description

technical field [0001] The invention relates to the technical field of information retrieval, in particular to an image retrieval method and system. Background technique [0002] Image retrieval has been a hot research topic in the multimedia field for nearly a decade. The image retrieval system is a type of professional search engine system that provides users with retrieval services for related graphic and image data on the Internet according to the descriptive text or visual characteristics of the image (ie, image content). For example, a series of search engines such as Google and Baidu can provide image search services. [0003] Traditional image retrieval relies on the descriptive text of pictures, and generally searches pictures in databases based on keywords. However, in many cases, text keywords cannot accurately describe the visual characteristics of images (such as a specific pattern), so retrieval technologies based on image content have emerged. At present, t...
