Problems solved by technology

This retrieval method relies solely on the similarity between the image to be retrieved and the image in the gallery, so that some images in the gallery that are related to the image to be retrieved but have a low similarity cannot be retrieved, resulting in a decrease in the accuracy of the retrieval results
For example, suppose it is necessary to retrieve related pictures of object A in the gallery, use a front face picture of subject A as a comparison picture, and search for similar pictures in the image base library according to the above retrieval method, then the other pictures of subject A will usually be output first. Frontal face pictures, frontal face pictures of other people similar to subject A (such as subject B), and for the side face pictures of subject A in the image library, although the correlation is high, the calculated similarity will be low, resulting in Its ranking is low and cannot be output as a TOPK search result picture, resulting in the missing object A's side face picture in the search result picture

Embodiment 1

[0028] First, refer to figure 1 An example electronic device 100 for implementing the image retrieval and reordering method, device and electronic device according to the embodiments of the present invention will be described.

[0029] Such as figure 1 A schematic structural diagram of an electronic device is shown, and the electronic device 100 includes one or more processors 102 and one or more memories 104 . Optionally, the electronic device may further include an input device 106, an output device 108, and may additionally include one or more image acquisition devices 110, and these components are interconnected through a bus system 112 and / or other forms of connection mechanisms (not shown) . It should be noted that figure 1 The shown components and structure of the electronic device 100 are exemplary rather than limiting, and the electronic device may also have other components and structures as required.

[0030] The processor 102 can be a central processing unit (C...

Embodiment 2

[0037] This embodiment provides a method for image retrieval and reordering. The execution subject of the image retrieval and reordering method may be a server, specifically a local server or a cloud server, and the local server may be a computer, a tablet computer, or a smart phone. This is not specifically limited. In one of the application scenarios of this method, the results of image retrieval are sorted and displayed, that is, the images to be retrieved are given. presented to the user in the exact order. Moreover, the operation object of the method is each base library picture in the preliminary sorting result obtained by preliminary sorting the retrieval results, that is, each candidate picture. The operation action of the method is to reorder each candidate picture.

[0038] Such as figure 2 Shown is a schematic flow chart of an image retrieval and reordering method, which consists of figure 2 Visible, this method comprises the following steps:

[0039] Step S2...

Embodiment 3

[0054] exist figure 2 On the basis of the picture retrieval reordering method shown, this embodiment also provides another picture retrieval reordering method, which focuses on the description of the above step S204 (based on the pictures similar to the candidate picture in the picture base library and the candidate picture) Retrieve the similarity degree of the picture, and determine the specific implementation manner of the second similarity degree corresponding to the candidate picture.

[0055] see image 3 , which is a schematic flowchart of another image retrieval and reordering method, wherein the method includes the following steps:

[0056] Step S302: Obtain an initial retrieval result of the image to be retrieved; wherein, the initial retrieval result includes a plurality of candidate images, and a first similarity between each candidate image and the image to be retrieved.

[0057] Step S302 in this embodiment corresponds to step S202 in the above embodiment, and...

Abstract

The invention provides a picture retrieval reordering method, electronic equipment and a computer readable storage medium. The method comprises the following steps: acquiring an initial retrieval result of a to-be-retrieved picture; wherein the initial retrieval result comprises a plurality of candidate pictures and a first similarity between each candidate picture and the to-be-retrieved picture; for each candidate picture, determining a second similarity corresponding to the candidate picture based on a similarity degree between a picture similar to the candidate picture in a picture base library and the to-be-retrieved picture; and reordering the plurality of candidate pictures based on the first similarity and the second similarity. According to the picture retrieval reordering method provided by the embodiment of the invention, on the basis of the initial retrieval result, the similarity between the similar picture of the candidate pictures in the picture base library and the to-be-retrieved picture is further considered, so that the similarity corresponding to the candidate pictures in the initial retrieval result is adjusted according to the similarity; therefore, the candidate pictures with high correlation are ranked in the front, and the accuracy of a retrieval result is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method for image retrieval and reordering, electronic equipment and a computer-readable storage medium. Background technique [0002] Existing image retrieval methods usually extract the features of the image to be retrieved first to obtain the corresponding image features, and then perform similarity calculation based on the image features and the image features in the gallery, and perform similarity calculation on the images that meet the similarity requirements according to the similarity value. Sort, and then filter out TOPK pictures to get the search results. This retrieval method relies solely on the similarity between the image to be retrieved and the image in the gallery, so that some images in the gallery that are related to the image to be retrieved but have a low similarity cannot be retrieved, resulting in a decrease in the accuracy of the retrieval...
