Abstract

The invention relates to the technical field of artificial intelligence, and particularly discloses a trademark similarity detection method and device, electronic equipment and a storage medium, and the trademark similarity detection method comprises the steps: carrying out data augmentation of a first trademark sample, and obtaining a second trademark sample; performing model training according to the second trademark sample to obtain a feature extraction model; inputting the to-be-detected first trademark image into a feature extraction model to obtain a first feature vector; inputting a to-be-detected second trademark image into the feature extraction model to obtain a second feature vector; determining the similarity between the first to-be-detected trademark image and the second to-be-detected trademark image according to the first feature vector and the second feature vector; and if the similarity is greater than a threshold value, determining that the first to-be-detected trademark image is similar to the second to-be-detected trademark image.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a trademark similarity detection method, device, electronic equipment and storage medium. Background technique [0002] A trademark, as a distinctive sign of the goods or services provided by an operator, represents the operator and its accumulated reputation in the field it operates to a certain extent, and symbolizes the reputation and reliability of the operator. An important part of the increasingly fierce market competition activities of enterprises. Moreover, due to the reputation of the operator represented by the trademark, the nature and quality of the product or service that the trademark can describe are consistent with the trademark. As such, consumers can be assisted in identifying and purchasing certain products or services. Based on this, a trademark can be said to be an intangible asset of an enterprise, and its importance is self-evident. There...
