Problems solved by technology

However, the existing method of "searching images by image" does not consider the specific content in the image when using image features for comparison. Therefore, the use of image features lacks pertinence, and the efficiency and accuracy of confirming image similarity are relatively low

Abstract

An embodiment of the invention discloses an image similarity confirmation method. The image similarity confirmation method comprises the following steps of confirming the first image confidence coefficient which is corresponding to at least one category; extracting at least one first visual characteristic of a first image; extracting at least one second visual characteristic of a second image; confirming the similarity of the first image and the second image at least according to the first image confidence coefficient which is corresponding to at least one category, the at least one first visual characteristic and the at least one second visual characteristic. The invention also discloses an image similarity confirmation device. The image similarity confirmation method and device can avoid the problem that the characteristic extraction in the prior art is lack of pertinence and improves the image similarity confirmation efficiency and accuracy.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a method and device for determining image similarity. Background technique [0002] With the popularization and rapid development of computer and network technology, multimedia data represented by images on the Internet has shown explosive growth. In daily life, people are accustomed to using image search engines to search for visual images of objects of interest. However, how to quickly and efficiently retrieve the images desired by users from massive image data is a challenging problem. Therefore, image retrieval technology is attracting extensive attention from researchers in different fields in academia and industry. [0003] Existing image retrieval techniques can be mainly divided into two categories: text-based image retrieval methods and content-based image retrieval methods. [0004] Text-based image retrieval methods usually use text information to describe ...
