Abstract

The invention discloses an image retrieval method and apparatus. The method comprises the steps of establishing a first image database and a second image database; based on sparse code feature information in the first image database, establishing a first similarity measurement database, and according to color feature information in the second image database, establishing a second similarity measurement database; obtaining a target weight, wherein the target weight is a weight preconfigured for the second similarity measurement database, or a weight preconfigured for the first similarity measurement database; according to the target weight, calculating a weighted sum of the first similarity measurement database and the second similarity measurement database, and taking the weighted sum as atarget similarity measurement database; and according to the target similarity measurement database, retrieving a to-be-retrieved image in preset images. The technical problem of relatively low retrieval accuracy of image retrieval and poor generalization capability of a retrieval system in the prior art are solved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image retrieval method and device. Background technique [0002] With the increase of pictures on the Internet at a molar rate, a large number of images are produced. It is becoming more and more important and urgent to establish an accurate and efficient image retrieval system. [0003] Currently, there are two widely used image retrieval techniques: one is text-based retrieval; the other is content-based retrieval. Text-based retrieval systems perform retrieval by matching retrieval keywords with image tags, where retrieval keywords are annotated by experienced experts. The content-based retrieval system mainly analyzes the information contained in the image itself, extracts image features, and searches through feature matching. Common image features include: texture features, spatial relationship features, shape features, etc. [0004] However, there are also man...
