The hierarchical structure of the retrieval strategy is analyzed to reach the real-time and retrieval accuracy requirement. A trademark image database system under hierarchical scheme is implemented: the string-matching method is first used to reduce the image search scope under man-machine interaction, then smallest enclosed rectangle and Hausdorff distance metric are used to measure the similarity between trademarks under image region normalization and transform invariance.
