User trademark image retrieval-based method and system

Abstract

The invention provides a user trademark image retrieval-based method and system and relates to the technical field of trademark image retrieval. The user trademark image retrieval-based method comprises the following steps: S1, obtaining a target trademark file, extracting an original trademark image, and establishing an original image database; s2, decomposing the original image, constructing a fragment image set, and extracting feature values in the set; s3, continuously performing feature fusion on the extracted feature value set to generate key points of the fragment image; and S4, constructing a supervised learning model, and training the key points of the fragment image by using the supervised learning model. According to the invention, the original trademark image is decomposed. According to the trademark image retrieval method and system, the feature values of the fragment images are obtained, then the feature values of the fragment images are utilized to obtain the key pointsof the fragment images, and then the key points of the fragment images are trained, so that the whole retrieval system can quickly retrieve the trademark images, the trademark images are convenientlyclassified, and the retrieval accuracy is greatly improved.

Description

technical field [0001] The invention relates to the technical field of trademark image retrieval, in particular to a method and system for user-based trademark image retrieval.

Problems solved by technology

[0003] Traditional trademark retrieval is text-based retrieval, including category-based retrieval and keyword-based retrieval. As the number of registered trademarks increases, traditional trademark retrieval technology has certain defects, for example: 1) The retrieval system is based on manual Classification management, the management cost is too high; 2) When there are relatively abstract trademark images, it is not easy to describe the image in the form of text, and it is not easy to classify; 3) There is no consistent measurement standard for the similarity of images, and it cannot guarantee whether the trademark classification is correct or not. correct
