Round seal authenticity identification method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention discloses a round seal authenticity identification method and device, electronic equipment and a storage medium. The method comprises: acquiring a picture containing a circular seal, wherein the number of the circular seal is at least one; identifying at least one circular seal image from the picture; performing multi-angle rotation processing on each circular seal image to obtain a plurality of candidate circular seal images corresponding to each circular seal image; and respectively calculating the similarity between each candidate circular seal image in the same circular seal image and at least one template seal image, and determining the authenticity judgment result of each circular seal image according to the similarity calculation result, so that the authenticity of the circular seal can be determined, and the identification accuracy of the circular seal can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of information processing, and in particular to a method, device, electronic device and storage medium for authenticity identification of a circular seal. Background technique [0002] With the progress of contemporary society and the diversified development of the economy, the functional departments of enterprises are becoming more and more detailed, and the types and application occasions of circular seals of various enterprises are also increasing. It is very important to identify the authenticity of circular seals Therefore, the requirements for the recognition accuracy of circular seals are getting higher and higher. [0003] Since the 1980s, many scholars at home and abroad have conducted a series of research on the authenticity identification of circular seals. The main processing process includes four parts: extraction, preprocessing, registration and analysis and judgment o...

[0003] Since the 1980s, many scholars at home and abroad have conducted a series of research on the authenticity identification of circular seals. The main processing process includes four parts: extraction, preprocessing, registration and analysis and judgment of circular seals. Each part is designed to improve the accuracy of circular stamp recognition. However, the extraction of circular stamps in the past uses traditional technical means, and the extraction of circular stamps is not accurate, and the recognition of circular stamps is accurate. low rate problem
