Embodiment Construction

[0066] The implementation of the present application will be described in detail below with reference to the accompanying drawings and examples, so as to fully understand and implement the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects.

[0067] The embodiment of the present invention is mainly applied to image retrieval to retrieve retrieval images containing target objects in the query image from the image database. Since images contain more abundant and objective information than text, using images for retrieval can obtain more precise search results. The traditional image retrieval method usually obtains the features of the query image and the candidate image in the image library, and calculates the similarity between the query image and the candidate image based on the image features of the image. By comparing the similarity between the query image and the candidate image, it is confirme...

Abstract

The application discloses an image retrieval method and device. The image retrieval method comprises the following steps: extracting image features of querying images and image features of candidate images in an image database and calculating the similarity between the querying images and candidate images through the image features; obtaining a first pre-set number of matching images similar to the querying images according to the descending order of similarity; obtaining a feature point which best matches a feature point in a querying image as for each feature point in each matching image inorder to form a to-be-checked point pair; checking a to-be-checked point corresponding to each matching image geometrically by use of a geometric constraint model in order to obtain a matching point pair in the geometric constraint relationship corresponding to each matching image; sequencing all matching images according to the descending order of matching point pair numbers corresponding to eachmatching point in order to obtain a first retrieval result. The embodiment of the image retrieval method and device helps increase accuracy of image retrieval.

Description

technical field [0001] The present application belongs to the field of image technology, and in particular relates to an image retrieval method and device. Background technique [0002] With the rapid growth of the mobile Internet, compared with traditional text-based keyword search methods, image retrieval may become a new growth point in the Internet industry and has been widely used because images can contain richer and more objective information. . [0003] The current image retrieval method is based on feature matching, specifically by extracting the image features of the query image and the candidate images in the image library, based on the image features, calculating the similarity between the query image and the candidate image, usually using Euclidean distance or cosine Distance representation; then search for matching images similar to the image from the candidate images, and arrange them in descending order of similarity, and output them as retrieval results, an...
