Abstract

The invention discloses an identifier identification method, device and system. The method comprises the steps: carrying out feature extraction on a commodity picture to be recognized, and obtaining an original feature layer reflecting the features of the commodity picture; according to the shortcut of the original feature layer, carrying out convolution operation and splicing operation on convolution kernels of different sizes and the original feature layer, and obtaining a fusion feature layer of the commodity picture; performing cross-layer connection on the fusion feature layer to obtain an identifier prediction feature layer of the commodity picture; and according to the identifier prediction feature layer, performing identifier identification on the commodity picture to determine whether the commodity corresponding to the commodity picture is a preset type of commodity. By adoption of the method provided by the invention, the problem of low identification accuracy for the identifier in the commodity picture in the prior art is solved.

Description

technical field [0001] The present application relates to the field of data mining, and in particular to a method, device and system for identification identification. Background technique [0002] E-commerce platforms provide consumers with a large number of commodities, which facilitates consumers' shopping needs. However, it is an urgent problem to quickly detect counterfeit goods from a large number of goods, so as to avoid the loss of consumers and the infringement of intellectual property rights. [0003] The prior art provides a method for identifying counterfeit commodities aimed at commodity logos in commodity pictures, and the method includes a retrieval method based on local features and a target detection method. The retrieval method based on local features has the advantage of convenient category expansion, but poor description of identification features; the target detection method is currently facing problems such as small targets, category expansion, and mod...
