A method and apparatus for image retrieval

Abstract

The embodiment of the invention provides a method and apparatus for image retrieval. The image retrieval method comprises the following steps: acquiring a target image to be retrieved, and preprocessing the target image; extracting color features, texture features and image names of target images to generate target feature vectors; inputting the target feature vector into a pre-established image retrieval model, so that the image retrieval model calculates the similarity between the target feature vector and the feature vector of each candidate image in the preset image feature library, determines each candidate image corresponding to the feature vector that meets the similarity judging condition as a desired image, and outputs the determined desired image from the preset image database. When the method provided by the embodiment of the invention is used for image retrieval, the subjectivity problem similar to that of adding keywords in the traditional image retrieval mode by the manual identification mode is not involved, so that the error probability in feature matching can be avoided, and the accuracy of the image retrieval result is greatly improved.

Description

technical field [0001] The invention relates to the technical field of image retrieval, in particular to an image retrieval method and device. Background technique [0002] Now is the era of great information development, all kinds of information are constantly impacting people's eyeballs, the amount of information is increasing, and the types of information data are also increasing, such as multimedia information such as video, audio and images. How to retrieve the desired multimedia information such as images from the vast database has become a problem worthy of attention. [0003] Traditional image retrieval is a retrieval technology based on image text description. Specifically, before image retrieval, an image index library needs to be established in advance. First, a text description is added to each candidate image in the image database. The text description here is the image attributes of the candidate image, such as image format, image name, Image size, creation t...
