A trademark pattern approximation query system and method

Abstract

The invention discloses a trademark pattern approximate query system and method. The trademark pattern approximate query system comprises a trademark pattern feature library generation subsystem, a convolutional neural network, a trademark pattern feature library and a trademark pattern query subsystem. The trademark pattern feature library generation subsystem provides an initial training set forthe convolutional neural network; the convolutional neural network is used for training a machine learning model for automatically processing trademark patterns; the trademark pattern features and the related index information are stored into a trademark pattern feature library; and when the query object trademark pattern is input, the trademark pattern feature library query subsystem performs feature matching on the query object trademark pattern and the trademark pattern stored in the trademark pattern feature library, and feeds back a matching result to the convolutional neural network tocomplete correction of the machine learning model. The trademark pattern serves as input, the intelligent algorithm based on the convolutional neural network is adopted to learn the features of the pattern in the feature library, manual marking is not needed, and the precision and efficiency of trademark pattern approximate query are improved.

Description

technical field [0001] The invention relates to a trademark pattern approximate query system and method. Background technique [0002] A trademark is a mark used by a company, product or service to distinguish an operator's brand or service from other operators' goods or services. It is integrated with the company's product quality, service quality, and management, and plays an important role in the industrial and commercial society The important role is an important attribute of the company and its products, and it is unique. In order for a trademark to be legally protected, it must be formally registered with the Trademark Office. With the development of my country's economy and the acceleration of globalization, the number of trademarks is increasing year by year. Preventing duplicate registration or registration of similar trademarks is the core issue of trademark management. In order to protect the legitimate rights and interests of registered trademarks and crack do...

Problems solved by technology

[0004] The present invention proposes a trademark pattern approximate query system and method, which solves the limitations of the existing technology in the recognition of trademark images with relatively complex images, the recognition rate is low, the retrieval efficiency is poor, and additional manual labeling is required. Labeling imprecise and unobjective problems
