Trademark Image Retrieval System Based on SIFT Algorithm

Abstract

In this paper, the theory of bag of view words model and sift algorithm is introduced for image retrieval, Try to use this model and algorithm to achieve trademark image matching. and the most dissimilarity coefficient is used for vector comparison to improve the accuracy. Based on this image matching algorithm, an image retrieval system is constructed for trademark image. The system matches the pictures with the corresponding trademark from the gallery, Help people get trademark information to a certain extent.
