Abstract

The invention provides a method and a device for searching images by using images, which are used for solving the technical problems of low image searching speed and low efficiency in the prior art. The method for searching images by using images comprises the following steps: carrying out dimension reduction processing on each image in an image library to obtain a feature vector of each image; calculating an average value of the feature vectors of all the images in the image library, and determining at least one reference image from the image library according to the average value; calculating and storing the similarity between each image in the image library and each reference image in the at least one reference image; after a image searching instruction is received, calculating the similarity between the to-be-searched image and each reference image; and searching Q images meeting a preset condition from the image library according to the similarity between the image to be searchedand each reference image and the similarity between each image in the image library and each reference image.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for searching images by images. Background technique [0002] As the data information of images on the Internet is becoming larger and larger, the requirements of users for image search on the Internet are also constantly increasing. In order to improve the accuracy of image search, the "search image by image" technology came into being, allowing users to search for similar images by inputting images. [0003] The search process of "searching pictures by pictures" in the prior art is: extracting the feature vectors of the picture to be searched and all the pictures in the gallery, and then comparing the feature vectors of the picture to be searched with the feature vectors of each picture in the gallery for similarity Compare, determine the pictures whose similarity is within the preset range, and present them as target pictures to the user, thus completing...
