Abstract: A novel and fast trademark retrieval system is proposed in this paper to deal with the rapid increase of trademarks. The proposed system uses chains of pre-image processing to provide a standardized contour image for feature extraction. The extracted features consist of outer shape feature and interior shape feature. A two-stage matching is used to retrieve similar trademarks. Outer shape feature matching is first used to retrieve trademarks with similar outer shape, the interior shape feature matching is then combined to refine the first stage retrieval results. Experimental results on a database of 300 trademarks were used to evaluate the performance of the proposed retrieval system. The experimental results show that the proposed two-stage retrieval method can successfully retrieve similar trademarks with identical shape features extracted from its contour image and its interior regions.
