Abstract:

This paper proposes a method of trademark image retrieval based on multifeature extraction. Firstly, the proposed approach commences with the extraction of edges using the Canny edge detector. Secondly, extracts the Hu moment invariant, eccentricity and centroid distance. Thirdly, Euclidean distance is used to measure the similarity between the query and database images. At last the performance of the proposed algorithm is compared with other algorithms.

Key words: trademark image retrieval, shape feature extraction, shape feature matching
