Problems solved by technology

[0004] However, the inventor has found that at least the following problems exist in the prior art: when searching for image files, the search results often appear in the search results that are very close in content but not exactly the same. According to the method of the prior art, data codes are excluded The same search results cannot exclude those search results with similar content, which makes the search results still have a lot of repeated invalid information, wasting a lot of system resources

Embodiment Construction

[0020] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Apparently, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] Such as figure 1 As shown, the flow of the method for image deduplication provided by the embodiment of the present invention specifically includes the following steps:

[0022] Step 101, the server obtains feature values ​​of a target picture and at least one reference picture.

[0023] When the user enters a search keyword in the user terminal and clicks the start search button, the terminal sends the corresponding search keyword to the server, and the server performs a correspon...

Abstract

The present invention discloses a method and device for image weight ranking. The method includes: obtaining feature values ​​of a target picture and at least one reference picture; The feature value differences are greater than a preset threshold; if yes, then determine that the target picture is not repeated with the reference picture, and keep the target picture; otherwise, determine that the target picture is repeated with the reference picture, and discard The target image. By adopting the method provided by the invention, the utilization efficiency of system resources can be improved.

Description

technical field [0001] The invention relates to the field of network technology, in particular to an image weight sorting method and device. Background technique [0002] With the development of Internet technology, web search has become one of the most commonly used means for people to browse the web and obtain information, and web image search is a very important part of web search. [0003] When the user terminal performs image search, the server searches for relevant image files according to the user's search keywords, and provides the search results to the user terminal. However, there are often a large number of repetitive pictures in the search results. Image deduplication is to exclude duplicate images from image search results. The image deduplication method adopted in the prior art generally obtains the data codes of the image files first, and then compares them. For image files with the same data code, only one of the image files is retained, and the other image...
