Embodiment Construction

[0073] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0074] figure 1 is a method flow chart of a similarity graph search method shown according to an exemplary embodiment, such as figure 1 As shown, the similarity map search method can be applied to a search device that provides image search. The search device that provides image search mentioned here can be a terminal or a server. The similarity map search method includes the following...

Abstract

The disclosure discloses a similarity graph search method and device, belonging to the field of image matching. The similarity graph search method includes: when searching for a similar image for the first image, input the first image into the image classification model Alexnet, control Alexnet to output the predetermined dimension feature of the first image; obtain the second image from a predetermined gallery, Input the second image into Alexnet, control Alexnet to output the predetermined dimensional features of the second image; calculate the matching degree between the predetermined dimensional features of the first image and the predetermined dimensional features of the second image; when the calculated matching degree is less than the predetermined When the threshold is reached, it is determined that the second image is a similar image to the first image. It solves the problem that the smoother image cannot successfully extract local feature points, which leads to the inability to realize the search of similarity graphs; it achieves the effect of successfully extracting local feature points of smoother images and improving the search rate of similarity graphs.

Description

technical field [0001] The present disclosure relates to the field of image matching, in particular to a similarity graph search method and device. Background technique [0002] Because the similarity image search technology can automatically identify similar images from a large number of images, it makes many applications based on similar image search possible. [0003] In the related art, when searching for similar images, first, for an image that needs to be searched for a similar image, extract local feature points in the image, perform feature description on the extracted local feature points, obtain a feature description document, and store these feature description documents Form a document inverted index tree; then, obtain an image from the gallery, and obtain the document inverted index tree of the image based on a similar method. When matching whether two images are similar images, according to the document inverted index tree of the two images Arrange the index t...
