Problems solved by technology

But when the number of pictures is small (for example, the number of pictures is about hundreds of thousands), the efficiency of determining similar pictures can meet the general needs, but as the amount of data increases (for example, to tens of millions or even billions), a single query may require It takes several minutes or even dozens of minutes, and the query efficiency is low, which obviously cannot meet our needs

Embodiment 1

[0027] figure 1 It is a schematic flow chart of a similar picture query method provided by Embodiment 1 of the present invention. This embodiment is applicable to the case where the coding information of the current picture is determined through the picture query model, and at least one of the current picture and the database server is determined according to the coding information. The similarity of a stored picture is used to determine the similarity of the current picture. This method can be executed by a similar picture query device, wherein the device can be implemented by software and / or hardware, and is generally integrated in the query server. For details, see figure 1 As shown, the method may include the following steps:

[0028] S110. Acquire the current picture, input the current picture into the pre-trained picture query model, and determine the encoding information of the current picture based on the feature information output by the picture query model.

Abstract

The embodiment of the invention discloses a similar picture query method, device, system and storage medium. By acquiring the current picture, input the current picture into the pre-trained picture query model, determine the coding information of the current picture based on the characteristic information output by the picture query model, and determine the current picture and the database server based on the coding information of the current picture The similarity of at least one stored picture is determined from the stored pictures according to the similarity calculation result to determine a similar picture of the current picture. Through the image query model, the coding information of the current image can be quickly determined, and it is beneficial to improve the calculation efficiency of the similarity between the current image and at least one stored image in the database server, so as to improve the query efficiency of similar images, and improve the efficiency of massive data. The speed of image search and image response.

Description

technical field [0001] Embodiments of the present invention relate to image search technology, and in particular to a similar image query method, device, system and storage medium. Background technique [0002] With the enrichment and development of Internet applications, we come into contact with more and more unstructured data, such as pictures and videos. Among them, similar image query is a basic but challenging task, so it has attracted much attention. [0003] The similar picture query in the prior art, as provided by major websites, is generally uploaded by the user in the query box, and the website performs image processing on the uploaded picture to obtain picture information, and calculates the gray value and hash value of the picture according to the picture information. Hash value, etc., and determine similar pictures of the picture according to the hash value. But when the number of pictures is small (for example, the number of pictures is about hundreds of th...
