Abstract

The embodiment of the invention provides a visual search method, a device and a device, wherein, the method comprises the following steps: acquiring a plurality of images to be retrieved; For each image to be retrieved, extracting the global feature information of the image to be retrieved. Calculating a complexity index corresponding to the image to be retrieved according to the global characteristic information of the image to be retrieved; Determining a code rate matching the complexity index; Based on the code rate, extracting and saving the image features of the image to be retrieved areextracted and saved, wherein The image features are used for visual search. The visual search method, the device and the device provided by the embodiment of the invention can reduce the waste of thestorage resources.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a visual search method, device and equipment. Background technique [0002] In order to meet the needs of users, the number of image and video transmissions has already occupied a large part of the network bandwidth. According to statistics, hundreds of millions of pictures are uploaded on the Internet every year. Under such a huge number, there is a hidden problem that needs to be solved. The problem is how to find the video or image that users need most in such a huge amount of data. [0003] In the visual search technology, by extracting the features of multiple images to be retrieved and saving the features of the images to be retrieved, when users need to search, they can query the features of the images and match them with the features of multiple images to be retrieved, and then search from multiple images to be retrieved. Search images to find images tha...
