Graphic similarity judgment method and device and computer readable storage medium

Abstract

The invention relates to the technical field of image detection, and discloses a graph similarity judgment method, which comprises the following steps of performing semantic segmentation on a target picture needing similarity comparison to obtain a target content label corresponding to the target picture after semantic segmentation; searching a known content tag database corresponding to known image characteristics according to the obtained target content tag, and identifying whether a known content tag which is the same as the target content tag exists in the database or not; and if the knowncontent tag which is the same as the target content tag exists, obtaining a known picture corresponding to the known content tag, carrying out image texture similarity comparison on the target picture and the known picture, and determining whether the target picture is similar to the known picture or not according to a comparison result. The invention further provides a graph similarity judgmentdevice and a computer readable storage medium. According to the method, the recognition efficiency and accuracy of the graph similarity are improved, and the retrieval efficiency and reliability of graphs are improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device and computer-readable storage medium for judging graphic similarity. Background technique [0002] When judging whether a graphic trademark is infringing, it is necessary to perform a similarity search on the image corresponding to the target trademark. Most of the current image retrieval is realized by comparing the similarity between images. The commonly used methods are: comparing based on pixel points and comparing the basic features of statistical images. The method based on pixel point comparison is: directly compare all the pixels of the target image and the original image one by one in order, and then obtain the similarity between the target image and the original image by calculating the Euclidean distance. This method needs to compare the pixels in the image one by one, which takes a long time and has high algorithm complexity. The co...
