Image similarity detection method and device and computer readable storage medium

Abstract

The application discloses an image similarity detection method and device and a computer readable storage medium. The method comprises the steps of: when a newly added image appears in any one image library, carrying out preprocessing on the newly added image, extracting a feature vector of the newly added image after preprocessing, carrying out dimensionality reduction processing on the extractedfeature vector, and storing the feature vector after dimensionality reduction processing to a feature library corresponding to the image library to which the newly added image belongs; and carrying out similarity index calculation on the newly added feature vector of each feature library and all the feature vectors of the feature libraries besides the feature library, and if a calculated similarity index is greater than a preset similarity index threshold, carrying out early warning prompt. According to the application, by extracting the feature vector of the newly added image and carrying out similarity index calculation on the newly added feature vector, a problem that a conventional identification method is fussy and low in efficiency is solved, and a function of automatically identifying a similar trademark image is achieved to a great degree, so that great convenience is brought to a user.

Description

Technical field [0001] The present invention relates to the technical field of image processing, in particular to an image similarity detection method and device, and a computer-readable storage medium. Background technique [0002] Trademarks are closely related to the company’s reputation and interests. If a company encounters a trademark infringement, not only will the company’s reputation be damaged, but also its interests will suffer significant damage. It will also cause a lot of trouble to the company’s future development. Most companies will pay close attention to whether other companies infringe their trademark rights on the market. One aspect is to check whether other companies use trademark images that are similar to the company's trademark. [0003] In response to this problem, most of the current methods used are: the traditional method of similarity retrieval based on trademark graphic coding or the method of manual inspection and discrimination. These methods requir...
